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: FTOS#May 31 01:46:17: %STKUNIT3-M:CP %IPC-2-STATUS: target stack unit 4 not responding May 31 01:46:17: %STKUNIT3-M:CP %CHMGR-2-STACKUNIT_DOWN: Major alarm: Stack unit 4 down - IPC timeout FTOS#May 31 01:46:17: %STKUNIT3-M:CP %IFMGR-1-DEL_PORT: Removed port: Te 4/1-32,41-48, Fo 4/ 49,53 FTOS#May 31 01:46:18: %STKUNIT5-S:CP %IFMGR-1-DEL_PORT: Removed port: Te 4/1-32,41-48, Fo 4/ 49,53 Unplugged Stacking Cable Problem: A stacking cable is unplugged from a member switch. The stack loses half of its bandwidth from the disconnected switch. Resolution: Intra-stack traffic is re-routed on a another link using the redundant stacking port on the switch. A recalculation of control plane and data plane connections is performed. Stacking | 215
