Multiple switch configurations

The Avaya 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.
The following considerations apply to NVRAM commands:
• The Nvram block that is not active is not reset to default after downgrade.
• You can save the switch binary configuration to the non-default NVRAM block.
• When you perform an agent code downgrade on the switch, only the configuration from
the default block resets to default.
Use the following ACLI commands to configure and use multiple switch configuration:
• show nvram block command
• copy config nvram block command
• copy nvram config block command
show nvram block command
This command shows the configurations currently stored on the switch. The syntax for this
command is
show nvram block
Example
show nvram block
