Feature Benefit

• 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 unprecedented flexibility in switch deployment.

• The default configuration stored in Flash memory ensures that the switch can be quickly connected to the

network and can pass traffic with minimal 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.

AVAILABILITY AND SCALABILITY

Superior Redundancy for

Fault Backup

• 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.

• Per-VLAN Rapid Spanning Tree Plus (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, fail-safe routing topologies.

• 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 675 support provides superior internal power-source redundancy for up to six Cisco networking

devices, resulting in improved fault tolerance and network uptime.

• Equal cost routing (ECR) provides load balancing and redundancy.

• Bandwidth aggregation 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 Express Forwarding hardware routing architecture delivers extremely high-performance IP routing.

• Basic IP unicast routing protocols (static, RIPv1, and RIPv2) 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 constructing scalable

LANs. EMI is required.

• Policy-Based Routing (PBR) allows superior control by enabl flow redirection regardless of the routing

protocol configured. EMI is required.

• Inter-VLAN IP routing provides for 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. EMI is required.
