NOTE:
Each unit in the stack has a stack number that is either assigned by you or Dell EMC Networking OS. To manually
renumber stack members, use the stack-unit old-unit-number renumber new-unit-number command.
Renumbering stack members causes the entire stack to reload.
Troubleshoot a Stack
To troubleshoot a stack, use the following recovery tasks.
• Recover from Stack Link Flaps
• Recover from a Card Problem State on a Stack
Recover from Stack Link Flaps
Stack link integrity monitoring enables units to monitor their own stack ports and disable any stack port that flaps five times within 10
seconds.
Dell EMC Networking OS displays console messages for the local and remote members of a flapping link, and on the primary (master) and
standby management units as KERN-2-INT messages if the flapping port belongs to either of these units.
In the following example, a stack-port on the master flaps. The remote member, Member 2, displays a console message, and the master
and standby display KERN-2-INT messages.
To re-enable the downed stack-port, power cycle the offending unit.
