Because of its flexibility, the 3000 series makes an excellent switch in small to midsize
campus environments and can be deployed as an access switch or a distribution switch.
The 3000 series can run either the IP Base image for Layer 2 switching or the IP Services
software image for Layer 2 and 3 switching. The IP Base image supports basic routing
such as RIP, static, and EIGRP stub routing.
Catalyst 4500 Series
The Catalyst 4500 series switch is a midline switch that can act as a high-port-density
access switch and distribution switch and a low-density core device. The 4500 series is
also a modular switch that offers both Layer 2 and Layer 3 services. This switch offers
Fast Ethernet, Gigabit Ethernet, and Ten Gigabit Ethernet connectivity. The Catalyst 4500
series offers a wide variety of supervisor engines—Supervisor II, IV, V, and VI. The
Supervisor IV, V, and VI for the 4500 series have an integrated Layer 3 switching capabili-
ty. These switches also perform Layer 2 trunking functions and provide support for
EtherChannel, QoS, and PoE.
The Catalyst 4500 also offers a fixed form factor switch, which is based on the chassis
Supervisor forwarding engine V and VI. The Catalyst 4948 is based on the Supervisor V,
and the Catalyst 4900M and is based on the Supervisor VI forwarding engine. The
