Feature Benefit

 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 CWDM

physical-interface support through a field-replaceable SFP module provides unprecedented flexibility in

switch deployment.

 To help ensure that the switch can be quickly connected to the network and can pass traffic with minimal

user intervention, there is a default configuration stored in Flash memory.

 Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if

an incorrect cable type (cross-over or straight-through) is installed.

AVAILABILITY AND SCALABILITY

Superior Redundancy for

Fault Backup

 1:N master redundancy allows each stack member to serve as a master, providing the highest reliability for

forwarding.

 Cisco CrossStack UplinkFast (CSUF) technology provides increased redundancy and network resiliency

through fast spanning-tree convergence (less than 2 seconds) across a switch stack with Cisco StackWise

technology.

 Cross-Stack EtherChannel provides the ability to configure Cisco EtherChannel technology across different

members of the stack for high resiliency.

 IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree convergence independent

of spanning-tree timers and also offers the benefit of distributed processing.

 Stacked units behave as a single spanning-tree node.

 Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN

spanning-tree basis, without requiring the implementation of spanning-tree instances.

 Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, failsafe routing topologies.

 Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by

incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.

 Switch-port autorecovery (errdisable) automatically attempts to reenable a link that is disabled because of a

network error.

 Cisco RPS 675 Redundant Power System support provides superior power-source redundancy for up to 6

Cisco networking devices, resulting in improved fault tolerance and network uptime.

 Equal-cost routing for load balancing and redundancy.

 Bandwidth aggregation up to 16 Gbps through 10 Gigabit EtherChannel technology, 8 Gbps through Gigabit

EtherChannel technology, and up to 800 Mbps through Fast EtherChannel technology enhances fault

tolerance and offers higher-speed aggregated bandwidth between switches and to routers and individual

servers.

 Uplink bandwidth can be easily upgraded by adding a 10 Gigabit Ethernet version to a wiring-closet stack

and replacing the 1 Gigabit Ethernet uplinks with 10 Gigabit Ethernet without having to change fiber pairs.

High-Performance

IP Routing

 Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing.

 Basic IP unicast routing protocols (static, Routing Information Protocol Version 1 [RIPv1], and RIPv2) are

supported for small-network routing applications.

 IPv6 routing support in hardware for maximum performance in the future.

 Advanced IP unicast routing protocols (Open Shortest Path First [OSPF], Interior Gateway Routing Protocol

[IGRP], Enhanced IGRP [EIGRP], and Border Gateway Protocol Version 4 [BGPv4]) are supported for load

balancing and constructing scalable LANs. Enhanced Multilayer Software Image (EMI) is required.

 Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless of the routing

protocol configured. EMI is required.

 HSRP provides dynamic load balancing and failover for routed links, up to 32 HSRP links supported per unit

or stack.

 Inter-VLAN IP routing for full Layer 3 routing between 2 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. EMI is required.

 Distance Vector Multicast Routing Protocol (DVMRP) tunneling interconnects 2 multicast-enabled networks

across nonmulticast networks. EMI is required.

 Fallback bridging forwards non-IP traffic between 2 or more VLANs. EMI is required.
