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

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
