Monitoring the Stack
As shown in the previous sections, monitoring the current status and operation of all elements in a stack
can help users avoid unexpected stack conditions. The table below includes CLI commands that are useful
in monitoring stack conditions.
Visually Monitoring the Stack
Users can also monitor many stack operations by viewing the front panel LEDs on all elements in the
stack. Refer to
“Status LEDs” on page 2-53
for detailed information on LEDs and stack status.
