• 8-MB DRAM and 4-MB Flash memory on board enable

the addition of a continuous stream of feature upgrades,

maximizing customer investments.

• Eight priority forwarding queues on each Gigabit Ethernet

port enable network trafﬁc prioritization and seamless

data, voice, and video integration (enabled through a

future software upgrade).

• Bandwidth aggregation through Gigabit EtherChannel

technology enhances fault tolerance and offers

higher-speed aggregated bandwidth between switches, to

routers and individual servers.

• A conﬁgurable network port supports unlimited MAC

addresses for backbone connectivity.

Flexible and Scalable Switch Clustering and Stacking

• GigaStack GBIC delivers a low-cost hardware-based,

independent stack bus with up to 1-Gbps forwarding

bandwidth in a daisy-chain conﬁguration with up to nine

Catalyst 3500 XL or gigabit-enabled Catalyst 2900 series

XL switches or 2-Gbps forwarding rate in a point-to-point

configuration.

• Cisco Switch Clustering technology allows the user to

manage up to 16 interconnected Catalyst 3500 XL,

2900 XL, and Catalyst 1900 switches through a single IP

address, without the limitation of being physically located

in the same wiring closet or building.

• GBIC-based Gigabit Ethernet ports give customers a

choice of 1000BaseSX, 1000BaseLX/LH or Cisco

GigaStack GBICs to ﬁt their connection needs.

Ease of Use and Ease of Deployment

• Cluster software upgrade feature allows the network

manager to quickly and easily upgrade the system software

on a group of Catalyst 3500 XL, and 2900 XL, and

Catalyst 1900 switches.

• IEEE 802.3z-compliant 1000BaseSX and 1000BaseLX/LH

physical-interface support through a ﬁeld-replaceable

GBICmodule provides customersunprecedented ﬂexibility

in switch deployment.

• Autoconﬁguration eases deployment of switches in the

network by automatically conﬁguring multiple switches

across a network via a boot server.

• Default conﬁguration stored in Flash ensures that the

switch can be quickly connected to the network and can

pass trafﬁc with minimal user intervention, preserving the

conﬁguration in case of a power outage.
