Command History
Usage Guidelines Catalyst 4500 series switches can be configured with two supervisor engines to provide redundancy.
When the switch is powered, one of the supervisor engines becomes active and remains active until a
switchover occurs. The other supervisor engine remains in standby mode.
Each supervisor engine has its own console port. Access to the standby supervisor engine is possible
only through the console port of the standby supervisor engine. Therefore, you must connect to the
standby console to access, monitor or debug the standby supervisor.
The virtual console for the standby supervisor engine enables you to access the standby console from the
active supervisor engine without requiring a physical connection to the standby console. It uses IPC over
EOBC to communicate with the standby supervisor engine and emulates the standby console on the
active supervisor engine. Only one active standby console session is active at any time.
The virtual console for the standby supervisor engine allows users who are logged onto the active
supervisor engine to remotely execute show commands on the standby supervisor engine and view the
results on the active supervisor engine. Virtual console is available only from the active supervisor
engine.
You can access the standby virtual console from the active supervisor engine with the attach module,
session module, or remote login commands on the active supervisor engine. You must be in privilege
EXEC mode (level 15) to run these commands to access the standby console.
Note The session module command is identical to the attach module mod and the remote login module mod
commands.
