ProCurve Stack Management

Operation

■If multiple VLANs are configured, stacking uses only the primary VLAN on any switch. In the factory-default configuration, the DEFAULT_VLAN is the primary VLAN. (See “Stacking Operation with Multiple VLANs Configured” on page 8-45and “The Primary VLAN” on page 2-7.)

■Stacking allows intermediate devices that do not support stacking. This enables you to include switches that are distant from the Commander.

Passwords optional. If the Candidate becomes a stack Member, it assumes the Commander’s Manager and Operator passwords.

If a candidate has a password, it cannot be automatically added to a stack. In this case, if you want the Candidate in a stack, you must manually add it to the stack.

Uses standard SNMP community operation if the Candidate has its own IP addressing.
