Stack Management for the Series 3400cl and 6400cl Switches
Configuring Stack Management
â– Stacking uses only the primary VLAN on each switch in a stack.
â– The primary VLAN can be tagged or untagged as needed in the
stacking path from switch to switch.
â– The same VLAN ID (VID) must be assigned to the primary VLAN in
each stacked switch.
Status Messages
Stacking screens and listings display these status messages:

join set to Candidate, Auto Join set to Yes (the
default), and no Manager password.

apply:
• Candidate has
Auto Join set to No.

Commander Member has lost connectivity to its Commander.
Down
Commander Up The Member has stacking connectivity with the
Commander.

date is trying to join a stack. If the Candidate does
not join, then stack configuration is inconsistent.

A possible cause is an interruption to the link
between the Member and the Commander.

Member.
