Catalyst 4000 Switch Integration
The AGM is a physically integrated but functionally independent Cisco IOS router inside the switch. It
is connected to the switch by a Gigabit Ethernet 802.1Q trunk on the backplane that supports multiple
VLANs. It can be used with the Catalyst operating system on the Supervisor II or with Cisco IOS on
Supervisor III and IV, but it must be configured separately from the Supervisor Engine.
The AGM can be configured and monitored from the following locations:
• the console port on the AGM
• the management port (10/100 ethernet) on the AGM
• the console or management port on the Supervisor Engine (with the session or attach module
command)
