High-Performance IP Routing

• Distributed CEF based routing architecture performed

in hardware to deliver extremely high performance

IP routing

• Support for all commonly deployed and industry

standard IP routing protocols including RIPv1, RIPv2,

OSPF, IGRP, EIGRP

• Fallback bridging support for non routable and

non IP protocols

• Multicast Routing Protocols supported is Protocol

Independent Multicast (PIM) (Sparse, Dense,

and Sparse-Dense modes)

• Support for Distance Vector Multicast Routing

Protocol (DVMRP) tunneling

• Support for Cisco Hot Standby Router Protocol

(HSRP) to create redundant failsafe routing topologies

Ease-of-Use and Ease-of-Deployment

• Cisco CMS allows the network administrator to

manage up to 16 inter-connected Catalyst 3550-12T,

Catalyst 2950, Catalyst 3500 XL, Catalyst 2900 XL,

and Catalyst 1900 switches through a single IP address

without the limitation of being physically located in

the same wiring closet

• Full backward compatibility ensures that any

Catalyst 2950, Catalyst 3500 XL, Catalyst 2900 XL,

or Catalyst 1900 switch can be managed with a

Catalyst 3550-12T using the Cisco Cluster

Management Suite

• Cisco Cluster Management Suite has been extended to

include multilayer feature conﬁgurations such as

Routing Protocol Conﬁguration, ACLs, and Quality

of Service parameters

• New Conﬁguration Template/Wizard to aid in switch

conﬁguration of a network that streams video

• New Guide Mode in the CMS assists users in

conﬁguration of high end features

• Enhanced online help in CMS for context-sensitive

assistance

• Autoconﬁguration eases deployment of switches in the

network by automatically conﬁguring multiple

switches across a network via a boot server

• Cluster software upgrade feature allows the user to

automatically upgrade the system software on a

group of Catalyst 3550-12T, Catalyst 2950,

Catalyst 3500 XL and Catalyst 2900 XL switches

• IEEE 802.3z compliant 1000BaseSX, 1000BaseLX/LH,

1000BaseZX, and 1000BaseT physical interface

support through a ﬁeld replaceable GBIC module

which provides customers unprecedented ﬂexibility

in switch deployment

• Auto-sensing on each port detects the speed of the

attached device and automatically conﬁgures the port

for 10, 100, or 1000 Mbps operation, easing the

deployment of the switch in mixed 10, 100, and

1000BaseT environments

• Auto-negotiating on all ports automatically selects

half- or full-duplex transmission mode to optimize

bandwidth

• Default conﬁguration stored in Flash ensures that the

switch can be quickly connected to the network and

can pass trafﬁc with minimal user intervention

Exceptional Performance

• 24 Gbps switching fabric and 12 Gbps forwarding rate

ensures maximum throughput even for the most

performance sensitive applications

• 10 10BaseT/100BaseTX/1000BaseT auto-sensing

ports and 2 GBIC-based Gigabit Ethernet ports

delivers up to 12 Gbps aggregated forwarding

bandwidth to small server farms or high performance

end stations

• 2 MB shared memory architecture ensures the highest

possible throughput with a design that eliminates

head-of-line blocking, minimizes packet loss, and

delivers better overall performance in environments

with extensive multicast and broadcast trafﬁc

• 32 MB DRAM and 8 MB Flash on-board enable the

addition of future feature upgrades, maximizing

customer investments

• Bandwidth aggregation up to 16 Gbps through

Gigabit EtherChannel enhances fault tolerance and

offers higher-speed aggregated bandwidth between

switches, to routers and individual servers

• Superior multicast management via support for IGMP

snooping in hardware
