OVERVIEW

Catalyst

2900 Series XL

The Cisco Catalyst

®

2900 Series XL is a full line

of 10/100 autosensing Fast Ethernet switches

from the leader in networking that combines

outstanding performance, ease of use, and

integratedCiscoIOS

®

software.TheCatalyst2900

Series XL includes six models, each with different

port densities, conﬁguration options, and pricing

to meet a broad range of network design

requirements.

The 24-port Catalyst 2924M XL switch is an

excellent aggregation device,as well as the perfect

solutionforprovidingdedicated10-or100-Mbps

bandwidth to individual users. The 12-port

Catalyst 2912MF XL switch is ideal for

aggregating small and mid-sized campus

networks over 100BaseFX ﬁber connections. The

two versatile module slots of the Catalyst

2912MF XL and Catalyst 2924M XL provide

expansion capabilities, higher-speed connectivity,

andsupportforfeaturemodules,allowing youthe

ﬂexibility to upgrade your network and preserve

your initial investment. The 12-port Catalyst

2912 XL, 24-port Catalyst 2924 XL and Catalyst

2924C XL switches are ideal for delivering

low-cost, high-performance, and 10- or 100-Mbps

bandwidth to individual users and servers. A

specialversion of theCatalyst2900 Series XL,the

Catalyst2924M DCforcentralofﬁce networks,is

designed especially for Telcos and other service

providers that require 48-volt DC Power.

Flexible Stacking with the

GigaStack GBIC

Gigabit Ethernet-enabled Catalyst 2900 SeriesXL

switches and Catalyst 3500 Series XL and can be

stacked using the low-cost two-port Cisco

GigaStack GBIC, which offers a range of highly

flexible stacking and performance options.

Customerscan deploy a1-Gbpsindependentstack

backplane in a cascade configuration, or scale up

to 5-Gbps of bandwidth in a star configuration

using the Catalyst 3508G Gigabit Ethernet

aggregation switch. Network managers may use

one or both of the available GBIC ports on a

Gigabit Ethernet-enabled Catalyst 2900 SeriesXL

switch to createhigh-speed uplinks to the network

core, using standard Gigabit Ethernet or Gigabit

EtherChannel technology. High resiliency canalso

be implemented by deploying dual Gigabit

Ethernetuplinks,aredundantGigaStackloopback

cable,CiscoUplinkFast technologyforhigh-speed

uplink failover, and PVST+ (Per VLAN Spanning

Tree) for uplink load balancing.

Cisco Switch Clustering

Breakthrough Cisco Switch Clustering technology

enablesupto16interconnected Catalyst3500XL,

2900 XL, and Catalyst 1900 switches, regardless

of geographic proximity, to form a single IP

management domain. Switch Clustering supports

a broad range of standards-based connectivity

options and configurations to deliver levels of

performance that are scalable to meet customer

requirements. Switch Clustering connectivity
