Stack Management for the Series 3400cl and 6400cl Switches
Configuring Stack Management
■ Stacking uses only the primary VLAN on each switch in a stack.
■ The primary VLAN can be tagged or untagged as needed in the
stacking path from switch to switch.
■ The same VLAN ID (VID) must be assigned to the primary VLAN in
each stacked switch.

Stacking screens and listings display these status messages:
