Several other commands can be used to configure the Supervisor Engine. The following list shows some of
them:
set boot config−register ignore−config enable—Sets the switch to ignore the contents of the
configuration on NVRAM at startup
•
set boot config−register 0xvalue [module number]—Sets the configuration register value•
set boot system flash device:[filename] [prepend] [module number]—Sets the system image to add
to the BOOT environment variable
•
clear boot system flash device:[filename] [module number]—Clears a specific image from the
BOOT environment variable
•
clear boot system all [module number]—Clears the entire BOOT environment variable•
show boot [module number]—Shows the current configuration register, BOOT environment
variable, and configuration file (CONFIG_FILE) environment variable settings

Changing the Management VLAN on a Supervisor Engine
By default, the switch places all of its ports into what Cisco refers to as a native management VLAN. The
native management VLAN is always configured for VLAN 1 on a Cisco switch. Cisco recommends adding
another layer of security by changing the default management VLAN from VLAN 1, which is the default of
all the ports on the module. To change the default VLAN from VLAN 1 to VLAN 3 on a Set/Clear
command−based IOS, you use the set interface sc0 <VLAN number> command. Let’s look at the command
and then examine the interface to see the changes:
Catalyst5002> (enable) set interface sc0 3
Interface sc0 vlan set.
Catalyst5002> (enable) show interfaces
sc0: flags=63<UP,BROADCAST,RUNNING>
vlan 3 inet 38.187.127.11 netmask 255.255.255.0 broadcast 38.187.127.255
Catalyst5002> (enable)
Viewing the Supervisor Engine Configuration
Using the show version command, you can see the software version installed on the Supervisor Engine:
