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 8-45 and “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.
