The Catalyst 5000 series of switches uses an architecture based on Supervisor Engines I, II, and III. The
Supervisor Engine provides network management and uplink ports. The Supervisor Engine II uses a fixed
configuration, but it supports Fast EtherChannel technology on all uplink ports. The Supervisor Engine III
module can be deployed in any Catalyst chassis. In a Catalyst 5500, 5505, or 5509, the Supervisor Engine III
enables the 3.6Gbps crossbar fabric. The Supervisor Engine III also has modular uplinks, with Fast
EtherChannel and Gigabit Ethernet support.
NetFlow LAN Switching provides multilayer switching for the Catalyst 5000 series. It is supported through
the NetFlow feature card, an upgrade that is available for Supervisor Engine III. Table E.9 shows the key
features of the Catalyst 5000 family of switches.

The Catalyst 5000 series has many switching modules that have made it popular for high−density wiring
closets and data center connectivity. These switching modules provide the ability to have a high port density
for connectivity to the desktop, in addition to a high−speed uplink.
Catalyst 6000 Series
The Catalyst 6000 series has become the popular choice for those upgrading from the Catalyst 5000 series.
These switches are designed to address the needs for gigabit scalability, high availability, and multilayer
