Usage Guidelines Catalyst 4500 series switches can be configured with two supe rvisor engines to provid e redundancy.
When the switch is powered, one of the supervisor engines becomes active and remains active until a
switchover occurs. The other superv isor engine remain s in standby mode.
Each supervisor engine has its own co nsole port. Access to the standby supervisor engi ne is possible
only through the console port of the sta ndby supervisor engine . Therefore, you must connect to the
standby console to access, monit or or debug the standby supervi sor.
The virtual console for t he standby su pervisor e ngine enab les you to a ccess the st andby con sole from the
active supervisor engine w ithout req uiring a phys ical conn ection to th e standby co nsole. It use s IPC over
EOBC to communicate with the standby supervisor engine and emulates the standby conso le on the
active supervisor engine. Only one active standby console session is active at any time.
The virtual console for the standby supe rvisor engine allow s users who are logged onto the active
supervisor engine to remotely execute show commands on the standby supervisor engine a nd 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 .
