Cisco Catalyst 2950 Series

Fast Ethernet Desktop Switches

Overview

The Cisco Catalyst

2950 Series of ﬁxed

conﬁguration, wire-speed Fast Ethernet desktop

switches delivers premium performance and

functionality for local-area networks (LANs). These

standalone, 10/100 autosensing switches provide

enhanced quality of service (QoS) and multicast

management features—managed with the

easy-to-use, Web-based Cisco Cluster Management

Suite (CMS) and integrated Cisco IOS

Software.

The Catalyst 2950 Gigabit-over-copper version with

10/100/1000BaseT uplinks offers medium-sized

businesses and enterprise branch ofﬁces with an ideal

solution to migrate from Fast Ethernet to a

higher-performance Gigabit Ethernet backbone using

existing Category 5 copper cabling.

The Catalyst 2950 Series consists of the Catalyst

2950T-24, 2950-24, 2950-12, and 2950C-24 switches.

The Catalyst 2950-24 Switch provides 24 10/100

ports; the 2950-12 has 12 10/100 ports; the 2950T-24

has 24 10/100 ports with 2 ﬁxed 10/100/1000BaseT

uplink ports; and the 2950C-24 has 24 10/100 ports

with 2 ﬁxed 100BaseFX uplink ports. Each switch has

a one rack-unit (RU) form factor, making them very

ﬂexible to deploy, either on a desktop or mounted in a

wiring closet (Figure 1).

Wire-Speed Performance in Connecting

End-Stations to the LAN

With a switching fabric of 8.8 Gigabits per second

(Gbps) and a maximum forwarding bandwidth of 4.4

Gbps, the Catalyst 2950 switches deliver wire-speed

performance on all ports in connecting end-stations

and users to the company LAN.

Catalyst 2950 switches support performance boosting

features such as Fast EtherChannel

and Gigabit

EtherChannel technology, offering up to 4-Gbps of

high-performance bandwidth between Catalyst

switches, routers, and servers.

Migrate to Gigabit Speeds in the LAN Multicast Management via IGMP Snooping Midmarket customers who have existing copper (Category 5, UTP) wiring infrastructure in their buildings now have a truly compelling solution to migrate to Gigabit speeds in their LANs. The Catalyst 2950T-24 delivers two fixed 10/100/1000BaseT (Gigabit-Ethernet-over-copper) uplink ports in addition to 24 10/100 ports for desktop connectivity.

Catalyst 2950 switches can be configured either as command or member switches in a Cisco switch cluster. The command switch serves as the single-IP address management point and disburses all management instructions dictated by the network administrator. Command switches can cluster up to 15 additional interconnected member switches regardless of interconnection media.
