The Cisco Catalyst 3750V2-24TS consumes less power than its predecessors and is the ideal access layer for enterprise, retail, and branch-office environments, as it increases productivity and investment protection by enabling a unified network for data, voice, and video. Cisco Catalyst 3750 v2 Series Overview: The Cisco Catalyst 3750 v2 Series Switches are next-generation energy-efficient Layer 3 Fast Ethernet stackable switches. This new series of switches supports Cisco EnergyWise technology, which enables companies to measure and manage power consumption of network infrastructure and network-attached devices, thereby reducing their energy costs and their carbon footprints. The Cisco Catalyst 3750 v2 Series consumes less power than its predecessors and is the ideal access layer for enterprise, retail, and branch-office environments, as it increases productivity and investment protection by enabling a unified network for data, voice, and video. Catalyst 3750 v2 Series Highlights Lower power consumption than its predecessors Backward compatible with Cisco Catalyst 3750 and 3750-E Series Switches EnergyWise support to monitor energy consumption of network infrastructure and implement energy saving programs to reduce energy costs Open Shortest path First (OSPF) routing with IP Base feature set Compatible with Cisco Redundant Power System (RPS) 2300 Uniform depth of 11.9 inches on all units for better cable management IPv6 routing included in the IP Services feature set   Cisco Catalyst 3750 v2 Series Software The Cisco Catalyst 3750 v2 Series can be purchased with the IP Base or IP Services license preinstalled. The IP Base license offers advanced quality of service (QoS), rate limiting, access control lists (ACLs), and basic static and Routing Information Protocol (RIP) and OSPF routing functions. The IP Services license provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and IP multicast routing as well as policy-based routing (PBR). The Advanced IP Services license, which includes IPv6 routing and IPv6 ACL support, is now included in the IP Services license. Upgrade licenses are available to upgrade a switch from the IP Base license to the IP Services license. Configurable Cisco IOS Software The Cisco Catalyst 3750 v2 Series can be preconfigured with a specific Cisco IOS Software release at the time of ordering. This option eliminates the need to reload a specific Cisco IOS Software release during deployment, thereby reducing deployment time and cost. The Cisco IOS Software release to be preloaded can be selected from a list of supported Cisco IOS Software releases, including the crypto version.   Power over Ethernet The Cisco Catalyst 3750 v2 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP Phones, Cisco Aironet® wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE eliminates the need for wall power outlets for each PoE-enabled device and significantly reduces the cost for additional electrical cabling that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst 3750 v2 24-port PoE switch can support Class 3 PoE or 15.4 watts (W) of PoE power on all 24 ports. Taking advantage of Cisco Catalyst Intelligent Power Management, the Cisco Catalyst 3750 v2 48-port PoE configurations can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. Maximum power availability for a converged voice and data network is attainable when a Cisco Catalyst 3750 v2 Series Switch is combined with the Cisco RPS 2300 for protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.   Cisco EnergyWise The Cisco Catalyst 3750 v2 Series supports Cisco EnergyWise, which is a technology that enables monitoring, reporting, and management of energy consumption by end devices that are EnergyWise enabled. This technology enables companies to reduce their energy costs and carbon footprints. EnergyWise features enable you to: Discover all Cisco EnergyWise enabled devices on the network Monitor and report power consumption by these devices Implement business rules to control power to these end devices   Redundant Power System The Cisco Catalyst 3750 v2 Series access switches support the new generation of Cisco RPS 2300, which increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3750 v2 Series Switches at the same time. The Cisco Catalyst 3750 v2 Series Switches are capable of reverting to their internal power supply without any service interruption. In addition, the Cisco RPS 2300 can be managed by a Cisco Catalyst 3750 v2 Series Switch that is connected to it.   Primary Features and Benefits The Cisco Catalyst 3750 v2 Series offers several ease-of-use features, which enable fast and easy configuration of advanced Cisco Catalyst capabilities. These features include: Cisco SmartPorts simplify the configuration of advanced Cisco Catalyst capabilities, encapsulating years of Cisco networking expertise. Cisco SmartPort macros offer a set of verified, pretested, recommended switch port configurations or templates per connection type that are easy to apply, enabling users to consistently and reliably configure essential security, IP telephony, availability, QoS, and manageability features with little effort and expertise. Cisco Auto-SmartPorts automatically execute SmartPort macros based on the end-device type, such as IP phones, desktop computers, and WLAN access points. Cisco Express Setup simplifies initial configuration with a web browser, eliminating the need for more complex terminal emulation programs and command-line interface (CLI) knowledge. IEEE 802.3af and Cisco prestandard PoE support comes with automatic discovery to detect a Cisco prestandard or IEEE 802.3af endpoint and provide the necessary power without any user configuration. Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment. DHCP AutoInstall simplifies the deployment of a large number of switches by automatically downloading a specified Cisco IOS Software image and a configuration file from a Trivial File Transfer Protocol (TFTP) server. This feature can be used to implement an automated, or zero-touch, deployment. DHCP Port-Based Allocation allows you to allocate the same IP address for a specified port. The feature allows persistent allocation of IP addresses to specified network devices. Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible tool for management and automation. This feature can be used to monitor network events and program automatic actions based on these network events. Policies can be defined through the CLI or through Tool Command Language (TCL) scripts and can be used in a variety of scenarios, such as automatic backup of a configuration file at a specified time or the triggering of an alert when traffic congestion crosses a specified threshold. Cisco IOS EEM requires the IP Services license. Configuration Replace and Rollback simplifies configuration management by allowing you to roll back configuration changes. This feature allows you to replace a configuration file with a saved configuration file without a switch reload; up to 14 configuration files can be saved. Automatic QoS (Auto-QoS) simplifies QoS configuration in voice-over-IP (VoIP) networks by sending interface and global switch commands to detect Cisco IP Phones, classify traffic, and enable egress queue configuration. Autosensing on each 10/100 port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing switch deployment in mixed 10- and 100-Mbps environments. Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth. Dynamic Trunking Protocol (DTP) helps enable dynamic trunk configuration across all switch ports. Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit EtherChannel groups to link to another switch, router, or server. Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP. DHCP Server enables a convenient deployment option for the assignment of IP addresses in networks that do not have a dedicated DHCP server. DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server. IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and coarse wavelength-division multiplexing (CWDM) physical interface support through a field-replaceable SFP module provides exceptional flexibility in switch deployment. The default configuration stored in flash memory helps ensure that the switch can be quickly connected to the network and can pass traffic with little user intervention. Automatic medium-dependent interface crossover (Auto-MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight through) is installed on a 10/100 port. Enhanced Security With the wide range of security features, such as ACLs, authentication, port-level security, and identity-based network services (IBNS) with IEEE 802.1x and extensions that the Cisco Catalyst 3750 v2 Series offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. These security features include the following: IEEE 802.1x allows dynamic, port-based security, providing user authentication. IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected. IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN regardless of the authorized or unauthorized state of the port. IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including those of the client. IEEE 802.1x with an ACL assignment allows specific identity-based security policies regardless of where the user is connected. IEEE 802.1x with guest VLAN allows guests without IEEE 802.1x clients to have limited network access on the guest VLAN. IEEE 802.1x supplicant on the switches can be used to authenticate switches on the network, thereby preventing unauthorized network devices from being used to expand the network. IEEE 802.1x readiness check eases IEEE 802.1x deployment in an enterprise. This feature determines whether the client has an IEEE 802.1x supplicant by initiating an IEEE 802.1x ping. Open IEEE 802.1x allows network communication to take place before IEEE 802.1x authentication. This feature is useful for preexecution environments (PXEs) and other applications in which network connectivity is required prior to IEEE 802.1x authentication. An ACL is used to allow traffic prior to authentication. Flexible authentication (FlexAuth) can be used to determine the order of authentication methods on the network. For example, if the order is set to IEEE 802.1x, MAC authentication bypass (MAB), and WebAuth, the network will first try to authenticate through IEEE 802.1x, then MAB, and then WebAuth. Multi-authentication (MultiAuth) enables up to eight users to authenticate through the same switch port. This feature includes support for multiple authentication methods, such as IEEE 802.1x, MAB, and WebAuth, and per-user ACLs. Web authentication for non-IEEE 802.1x clients allows non-IEEE 802.1x clients to use an SSL-based browser for authentication. Local web authentication allows non-IEEE 802.1x users to authenticate through a login webpage. The user enters the authentication information, such as a user ID and password, and is authenticated through an authentication, authorization, and accounting (AAA) server. The local web authentication banner allows users to customize the authentication webpage. Multidomain authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate voice and data VLANs. MAB for voice allows third-party IP phones without an IEEE 802.1x supplicant to be authenticated using the MAC address. Cisco security VLAN ACLs (VACLs) on all VLANs prevent unauthorized data flows from being bridged within VLANs. Cisco standard and extended IP security router ACLs (RACLs) define security policies on routed interfaces for control- and data-plane traffic. Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server (VMPS) client functions to provide flexibility in assigning ports to VLANs. Dynamic VLAN helps enable fast assignment of IP addresses. Cisco Network Assistant software security wizards ease the deployment of security features for restricting user access to a server as well as to a portion of or the entire network. Two thousand access control entries are supported. Availability and Scalability The Cisco Catalyst 3750 v2 Series is equipped with a robust set of features that allow network scalability and higher availability through IP routing as well as a complete suite of Spanning Tree Protocol enhancements that help increase availability in a Layer 2 network. Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), Uplink Fast, and PortFast, increase network uptime. PVST+ allows Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design. Uplink Fast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second Spanning Tree Protocol convergence time. Loop guard and BPDU guard provide Spanning Tree Protocol loop avoidance. Superior redundancy features include the following: Cisco Uplink Fast and BackboneFast technologies help ensure quick failover recovery, enhancing overall network stability and reliability. IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree convergence independent of spanning-tree timers and the benefit of distributed processing. PVRST+ allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring implementation of spanning-tree instances. Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, fail-safe routing topologies. FlexLink enables fast failover for redundant links in a Layer 2 network. FlexLink offers a faster convergence than Spanning Tree Protocol and eliminates the need for Spanning Tree Protocol. FlexLink load balancing allows both the primary and the backup links to carry traffic for different sets of VLANs. If an interface fails, the peer interface will carry all the traffic for all VLANs. Command-switch redundancy enabled in Cisco Network Assistant software allows designation of a backup command switch that takes over cluster-management functions if the primary command switch fails. Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links to be detected and disabled to avoid problems such as spanning-tree loops. Switch port autorecovery (errdisable) automatically attempts to reenable a link that is disabled because of a network error. Cisco RPS 2300 support provides superior internal power-source redundancy, resulting in improved fault tolerance and network uptime. Equal-cost routing (ECR) provides load balancing and redundancy. Bandwidth aggregation of up to 8 Gbps through Cisco Gigabit EtherChannel technology and up to 800 Mbps through Cisco Fast EtherChannel technology enhances fault tolerance and offers higher-speed aggregated bandwidth between switches and to routers and individual servers. High-Performance IP Routing Cisco Catalyst 3750 v2 Series Switches deliver high-performance, hardware-based IP routing. The Cisco Express Forwarding CEF/dCEF) routing architecture enables outstanding scalability and performance. Implementation of routed uplinks to the core improves network availability by enabling faster failover protection and simplifying the Spanning Tree Protocol algorithm by terminating all Spanning Tree Protocol instances at the aggregator switch. If one of the uplinks fails, quicker failover to the redundant uplink can be achieved with a scalable routing protocol such as Open Shortest Path First (OSPF) or Enhanced Interior Gateway Routing Protocol (EIGRP) rather than relying on standard Spanning Tree Protocol convergence. Redirection of a packet after a link failure using a routing protocol results in faster failover than a solution that uses Layer 2 spanning-tree enhancements. Additionally, routed uplinks allow better bandwidth use by implementing ECR on the uplinks to perform load balancing. Routed uplinks optimize the utility of uplinks out of the LAN by eliminating unnecessary broadcast data flows into the network backbone. Other high-performance routing features include the following: Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing. Basic IP unicast routing protocols (static, RIPv1, RIPv2, EIGRP-Stub and OSPF) are supported for small-network routing applications. Advanced IP unicast routing protocols (OSPF, Interior Gateway Routing Protocol [IGRP], EIGRP, and Border Gateway Protocol Version 4 [BGPv4]) are supported for load balancing and construction of scalable LANs. The IP Services license is required. IPv6 unicast routing capability (static, RIP, OSPF, and EIGRP) forwards IPv6 traffic through configured interfaces (the IP Services license is required). PBR allows superior control by enabling flow redirection regardless of the routing protocol configured. The IP Services license is required. Inter-VLAN IP routing provides full Layer 3 routing between two or more VLANs. Protocol Independent Multicast (PIM) for IP multicast routing is supported, including PIM sparse mode (PIM-SM), PIM dense mode (PIM-DM), and PIM sparse-dense mode. The IP Services license is required. Distance Vector Multicast Routing Protocol (DVMRP) tunneling interconnects two multicast-enabled networks across nonmulticast networks. The IP Services license is required. Fallback bridging forwards non-IP traffic between two or more VLANs. The IP Services license is required. Integrated Cisco IOS Software Features for Bandwidth Optimization The Cisco Catalyst 3750 v2 Series offers several advanced features for bandwidth optimization: Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall system performance. IEEE 802.1d Spanning Tree Protocol support for redundant backbone connections and loop-free networks simplifies network configuration and improves fault tolerance. PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design. IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allows a spanning-tree instance per VLAN, enabling Layer 2 load sharing on redundant links. ECR provides load balancing and redundancy. Virtual Route Forwarding (VRF) Lite enables a service provider to support two or more VPNs with overlapping IP addresses. VRF-aware IP services enable the use of functions such as TFTP, FTP, syslog, SNMP, traceroute, ping, HSRP, ARP, and IP service-level agreements (SLAs) within a VRF instance. Local Proxy ARP works in conjunction with Private VLAN Edge to reduce broadcasts and increase available bandwidth. VLAN1 reduction allows VLAN1 to be disabled on any individual VLAN trunk link. VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by flooding broadcast traffic only on trunk links required to reach the destination devices. IGMPv3 snooping for IPv4 and IPv6 Multicast Listener Discovery Versions 1 and 2 (MLDv1 and v2) snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requestors. IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port. Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons. Source-Specific Multicast (SSM) simplifies multicast deployment and optimizes bandwidth for one-to-many applications, such as a corporate video broadcast. Multicast VRF-Lite enables multicast virtualization and separation of VRF traffic. EIGRP stub and PIM stub enable multicast and routing on the uplinks, within the IP Base feature set. The Cisco MAC Notification MIB enables you to monitor MAC table use and to track end-device movement across the network. This feature also allows you to set threshold limits for notification of MAC changes.

DHCP AutoInstall simplifies the deployment of a large number of switches by automatically downloading a specified Cisco IOS Software image and a configuration file from a Trivial File Transfer Protocol (TFTP) server. This feature can be used to implement an automated, or zero-touch, deployment. DHCP Port-Based Allocation allows you to allocate the same IP address for a specified port. The feature allows persistent allocation of IP addresses to specified network devices. Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible tool for management and automation. This feature can be used to monitor network events and program automatic actions based on these network events. Policies can be defined through the CLI or through Tool Command Language (TCL) scripts and can be used in a variety of scenarios, such as automatic backup of a configuration file at a specified time or the triggering of an alert when traffic congestion crosses a specified threshold. Cisco IOS EEM requires the IP Services license. Configuration Replace and Rollback simplifies configuration management by allowing you to roll back configuration changes. This feature allows you to replace a configuration file with a saved configuration file without a switch reload; up to 14 configuration files can be saved. Automatic QoS (Auto-QoS) simplifies QoS configuration in voice-over-IP (VoIP) networks by sending interface and global switch commands to detect Cisco IP Phones, classify traffic, and enable egress queue configuration. Autosensing on each 10/100 port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing switch deployment in mixed 10- and 100-Mbps environments. Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth. Dynamic Trunking Protocol (DTP) helps enable dynamic trunk configuration across all switch ports. Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit EtherChannel groups to link to another switch, router, or server. Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP. DHCP Server enables a convenient deployment option for the assignment of IP addresses in networks that do not have a dedicated DHCP server. DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server. IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and coarse wavelength-division multiplexing (CWDM) physical interface support through a field-replaceable SFP module provides exceptional flexibility in switch deployment. The default configuration stored in flash memory helps ensure that the switch can be quickly connected to the network and can pass traffic with little user intervention. Automatic medium-dependent interface crossover (Auto-MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight through) is installed on a 10/100 port. Enhanced Security With the wide range of security features, such as ACLs, authentication, port-level security, and identity-based network services (IBNS) with IEEE 802.1x and extensions that the Cisco Catalyst 3750 v2 Series offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. These security features include the following: IEEE 802.1x allows dynamic, port-based security, providing user authentication. IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected. IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN regardless of the authorized or unauthorized state of the port. IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including those of the client. IEEE 802.1x with an ACL assignment allows specific identity-based security policies regardless of where the user is connected. IEEE 802.1x with guest VLAN allows guests without IEEE 802.1x clients to have limited network access on the guest VLAN. IEEE 802.1x supplicant on the switches can be used to authenticate switches on the network, thereby preventing unauthorized network devices from being used to expand the network. IEEE 802.1x readiness check eases IEEE 802.1x deployment in an enterprise. This feature determines whether the client has an IEEE 802.1x supplicant by initiating an IEEE 802.1x ping. Open IEEE 802.1x allows network communication to take place before IEEE 802.1x authentication. This feature is useful for preexecution environments (PXEs) and other applications in which network connectivity is required prior to IEEE 802.1x authentication. An ACL is used to allow traffic prior to authentication. Flexible authentication (FlexAuth) can be used to determine the order of authentication methods on the network. For example, if the order is set to IEEE 802.1x, MAC authentication bypass (MAB), and WebAuth, the network will first try to authenticate through IEEE 802.1x, then MAB, and then WebAuth. Multi-authentication (MultiAuth) enables up to eight users to authenticate through the same switch port. This feature includes support for multiple authentication methods, such as IEEE 802.1x, MAB, and WebAuth, and per-user ACLs. Web authentication for non-IEEE 802.1x clients allows non-IEEE 802.1x clients to use an SSL-based browser for authentication. Local web authentication allows non-IEEE 802.1x users to authenticate through a login webpage. The user enters the authentication information, such as a user ID and password, and is authenticated through an authentication, authorization, and accounting (AAA) server. The local web authentication banner allows users to customize the authentication webpage. Multidomain authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate voice and data VLANs. MAB for voice allows third-party IP phones without an IEEE 802.1x supplicant to be authenticated using the MAC address. Cisco security VLAN ACLs (VACLs) on all VLANs prevent unauthorized data flows from being bridged within VLANs. Cisco standard and extended IP security router ACLs (RACLs) define security policies on routed interfaces for control- and data-plane traffic. Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server (VMPS) client functions to provide flexibility in assigning ports to VLANs. Dynamic VLAN helps enable fast assignment of IP addresses. Cisco Network Assistant software security wizards ease the deployment of security features for restricting user access to a server as well as to a portion of or the entire network. Two thousand access control entries are supported. Availability and Scalability The Cisco Catalyst 3750 v2 Series is equipped with a robust set of features that allow network scalability and higher availability through IP routing as well as a complete suite of Spanning Tree Protocol enhancements that help increase availability in a Layer 2 network. Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), Uplink Fast, and PortFast, increase network uptime. PVST+ allows Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design. Uplink Fast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second Spanning Tree Protocol convergence time. Loop guard and BPDU guard provide Spanning Tree Protocol loop avoidance. Superior redundancy features include the following: Cisco Uplink Fast and BackboneFast technologies help ensure quick failover recovery, enhancing overall network stability and reliability. IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree convergence independent of spanning-tree timers and the benefit of distributed processing. PVRST+ allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring implementation of spanning-tree instances. Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, fail-safe routing topologies. FlexLink enables fast failover for redundant links in a Layer 2 network. FlexLink offers a faster convergence than Spanning Tree Protocol and eliminates the need for Spanning Tree Protocol. FlexLink load balancing allows both the primary and the backup links to carry traffic for different sets of VLANs. If an interface fails, the peer interface will carry all the traffic for all VLANs. Command-switch redundancy enabled in Cisco Network Assistant software allows designation of a backup command switch that takes over cluster-management functions if the primary command switch fails. Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links to be detected and disabled to avoid problems such as spanning-tree loops. Switch port autorecovery (errdisable) automatically attempts to reenable a link that is disabled because of a network error. Cisco RPS 2300 support provides superior internal power-source redundancy, resulting in improved fault tolerance and network uptime. Equal-cost routing (ECR) provides load balancing and redundancy. Bandwidth aggregation of up to 8 Gbps through Cisco Gigabit EtherChannel technology and up to 800 Mbps through Cisco Fast EtherChannel technology enhances fault tolerance and offers higher-speed aggregated bandwidth between switches and to routers and individual servers. High-Performance IP Routing Cisco Catalyst 3750 v2 Series Switches deliver high-performance, hardware-based IP routing. The Cisco Express Forwarding CEF/dCEF) routing architecture enables outstanding scalability and performance. Implementation of routed uplinks to the core improves network availability by enabling faster failover protection and simplifying the Spanning Tree Protocol algorithm by terminating all Spanning Tree Protocol instances at the aggregator switch. If one of the uplinks fails, quicker failover to the redundant uplink can be achieved with a scalable routing protocol such as Open Shortest Path First (OSPF) or Enhanced Interior Gateway Routing Protocol (EIGRP) rather than relying on standard Spanning Tree Protocol convergence. Redirection of a packet after a link failure using a routing protocol results in faster failover than a solution that uses Layer 2 spanning-tree enhancements. Additionally, routed uplinks allow better bandwidth use by implementing ECR on the uplinks to perform load balancing. Routed uplinks optimize the utility of uplinks out of the LAN by eliminating unnecessary broadcast data flows into the network backbone. Other high-performance routing features include the following: Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing. Basic IP unicast routing protocols (static, RIPv1, RIPv2, EIGRP-Stub and OSPF) are supported for small-network routing applications. Advanced IP unicast routing protocols (OSPF, Interior Gateway Routing Protocol [IGRP], EIGRP, and Border Gateway Protocol Version 4 [BGPv4]) are supported for load balancing and construction of scalable LANs. The IP Services license is required. IPv6 unicast routing capability (static, RIP, OSPF, and EIGRP) forwards IPv6 traffic through configured interfaces (the IP Services license is required). PBR allows superior control by enabling flow redirection regardless of the routing protocol configured. The IP Services license is required. Inter-VLAN IP routing provides full Layer 3 routing between two or more VLANs. Protocol Independent Multicast (PIM) for IP multicast routing is supported, including PIM sparse mode (PIM-SM), PIM dense mode (PIM-DM), and PIM sparse-dense mode. The IP Services license is required. Distance Vector Multicast Routing Protocol (DVMRP) tunneling interconnects two multicast-enabled networks across nonmulticast networks. The IP Services license is required. Fallback bridging forwards non-IP traffic between two or more VLANs. The IP Services license is required. Integrated Cisco IOS Software Features for Bandwidth Optimization The Cisco Catalyst 3750 v2 Series offers several advanced features for bandwidth optimization: Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall system performance. IEEE 802.1d Spanning Tree Protocol support for redundant backbone connections and loop-free networks simplifies network configuration and improves fault tolerance. PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design. IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allows a spanning-tree instance per VLAN, enabling Layer 2 load sharing on redundant links. ECR provides load balancing and redundancy. Virtual Route Forwarding (VRF) Lite enables a service provider to support two or more VPNs with overlapping IP addresses. VRF-aware IP services enable the use of functions such as TFTP, FTP, syslog, SNMP, traceroute, ping, HSRP, ARP, and IP service-level agreements (SLAs) within a VRF instance. Local Proxy ARP works in conjunction with Private VLAN Edge to reduce broadcasts and increase available bandwidth. VLAN1 reduction allows VLAN1 to be disabled on any individual VLAN trunk link. VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by flooding broadcast traffic only on trunk links required to reach the destination devices. IGMPv3 snooping for IPv4 and IPv6 Multicast Listener Discovery Versions 1 and 2 (MLDv1 and v2) snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requestors. IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port. Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons. Source-Specific Multicast (SSM) simplifies multicast deployment and optimizes bandwidth for one-to-many applications, such as a corporate video broadcast. Multicast VRF-Lite enables multicast virtualization and separation of VRF traffic. EIGRP stub and PIM stub enable multicast and routing on the uplinks, within the IP Base feature set. The Cisco MAC Notification MIB enables you to monitor MAC table use and to track end-device movement across the network. This feature also allows you to set threshold limits for notification of MAC changes.
