Important Considerations About Using Clear Config in a Stack

When using the clear config command (as described in the SecureStack A2 Configuration Guide)

to clear configuration parameters in a stack, it is important to remember the following:

• Use clear config to clear config parameters without clearing stack switch IDs. This command

WILL NOT clear stack parameters and avoids the process of re-numbering the stack.

• Use clear config all when it is necessary to clear all config parameters, including stack switch

IDs and switch priority values.
