Switch administration tasks
Multiple switch configurations
The Nortel Ethernet Routing Switch 4500 Series supports the storage
of two switch configurations in flash memory. The switch can use either
configuration and must be reset for the configuration change to take effect.
A regular reset of the switch synchronizes configuration changes to the
active configuration, whereas a reset to defaults sets configuration to factory
defaults. The inactive block is not affected.
In stack configurations, all units in the stack must use the same active
configuration. If a unit joins a stack, a check is performed between the unit
active configuration and the stack active configuration. If the two differ, the
new stack unit resets and loads the stack active configuration.
Use the following CLI commands to configure and use multiple switch
configuration:
•
"show nvram block command" (page 170)
•
"copy config nvram block command" (page 170)
•
"copy nvram config block command" (page 171)
