The Catalyst 5000 Family offers a variety of choices of Gigabit

Ethernet products, from high-density Gigabit Ethernet switching

modules for powerful Gigabit switching in high-performance

backbones to uplink modules that aggregate traffic from

high-density 10-/100-Mbps wiring closets. The complete range of

Gigabit Ethernet switching and uplink modules from Cisco

extend the Catalyst 5000 Family to more than 50 Gbps and

throughput of tens of millions of packets per second (pps). By

making use of multiple modules in the Catalyst 5500 Family, port

densities of up to 38 ports of Gigabit Ethernet per Catalyst 5509

chassis are possible. In addition, Gigabit Ethernet port

aggregation is supported via Gigabit EtherChannel

®

, providing up

to 8 Gbps of throughput on a single logical link between devices.

A Flexible Choice of Gigabit Switching Solutions (top to bottom:

Supervisor Engine III with two-port Gigabit Ethernet uplinks, three-port
Gigabit Ethernet switching module, nine-port Gigabit EtherChannel module)

Supervisor Engine III A, Supervisor Engine II G, and Supervisor

Engine III G can all be deployed in the Catalyst 5000, 5502, 5505,

5509, or 5500 chassis. Supervisor Engine III G provides dual

GBIC based Gigabit Ethernet uplinks, allowing customers the

flexibility of multiple distance configurations.

In addition to Fast Ethernet and Fast EtherChannel uplink

modules, Supervisor Engine III A and Supervisor Engine II G

offer two-port Gigabit Ethernet uplink modules to provide

the performance, scalability, flexibility, and redundancy required

for building large, switched intranets. The latest two-port GBIC

uplink module delivers QoS capabilities to the uplinks, allowing

customers to build end-to-end QoS networks. These uplink

modules can be used or upgraded interchangeably as network

needs grow to accommodate Gigabit speeds. This flexible

solution helps maintain your current network infrastructure

design.

The nine-port Gigabit EtherChannel switching module offers up

to nine ports of switched Gigabit Ethernet per module. With

integrated nonblocking wire-speed local switching, up to 24 Gbps

of bandwidth of switching capacity are provided on each module.

Data between two ports on the module is switched onboard at wire

rates, without crossing the chassis central crossbar fabric. Even if
