Data Sheet

Feature Benefit

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.



IPv6 unicast routing capability (static, RIP, and OSPF protocols) forwards IPv6 traffic

through configured interfaces (requires the Advanced IP Services license).



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. The IP Services license is required.



Policy-Based Routing (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 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. 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



Per-port broadcast, multicast, and unicast storm control prevents faulty end stations

from degrading overall systems 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 extra

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.



VPN routing/forwarding (VRF)-Lite enables a service provider to support two or more

VPNs, with overlapping IP addresses.



Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private

VLAN Edge to minimize broadcasts and maximize available bandwidth.



VLAN1 minimization 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.



Internet Group Management Protocol v3 (IGMP) Snooping for IPv4 and IPv6 MLD v1

and v2 Snooping provide fast client joins and leaves of multicast streams and limits

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.

QoS and Control

Advanced QoS



Standard 802.1p CoS and DSCP field classification are provided, using marking and

reclassification on a per-packet basis by source and destination IP address, source

and destination MAC address, or Layer 4 TCP or UDP port number.



Cisco control- and data-plane QoS ACLs on all ports help ensure proper marking on

a per-packet basis.



Four egress queues per port enable differentiated management of up to four traffic

types across the stack.



SRR scheduling ensures differential prioritization of packet flows by intelligently

servicing the ingress and egress queues.



Weighted tail drop (WTD) provides congestion avoidance at the ingress and egress

queues before a disruption occurs.



Strict priority queuing guarantees that the highest-priority packets are serviced ahead

of all other traffic.



There is no performance penalty for highly granular QoS functions.

Granular Rate Limiting



The Cisco Committed Information Rate (CIR) function guarantees bandwidth in

increments as low as 8 kbps.



Rate limiting is provided based on source and destination IP address, source and

destination MAC address, Layer 4 TCP and UDP information, or any combination

of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy

maps.



Asynchronous data flows upstream and downstream from the end station or

on the uplink are easily managed using ingress policing and egress shaping.
