Stack Troubleshooting and Maintenance

Replacing a Failed Member Stack Unit in an Operational Stack

If a unit that is not the Stack Master fails in an operational stack, the Stack Master discovers that the unit
is no longer responding during the Master Discovery process. The Stack Master directs all other stack
members to route unit-to-unit traffic around the failed unit using the ring topology of the stacking
connections. Concurrently, the Stack Master notifies the system administrator of the failure by sending
SYSLOG messages and SNMP traps.
Because all traffic has been routed around the failed unit, when it is disconnected from the stack, the
stack continues to run as long as all other stacking connections are left intact.
