show stack neighbors

Enter the

 show stack neighbors

 command at the device level. This command displays neighboring

units for each stack port. . In case when a unit turns bad this output is useful to debug the neighboring
units are detected or not.

show stack connections

Enter the 

show stack connection

 command at the device level. This command displays total

stacking links on the topology along with stack port 1(P0) and stack port 2(P1) for each stacking link. It
also displays CPU to CPU packets are fine between the units. If the stack ports link goes down, this
output helps debug if the neighboring links are detected or not.
