Failure Scenarios
The following sections describe some of the common fault conditions that can happen in a switch stack
and how they are resolved.
Stack Member Fails
• Problem: A unit that is not the stack master fails in an operational stack.
• Resolution: If a stack member fails in a daisy chain topology, a split stack occurs. If a member unit
fails in a ring topology, traffic is re-routed over existing stack links.
The following syslog messages are generated when a member unit fails:
