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 aps ve times within
10 seconds.
Dell Networking OS displays console messages for the local and remote members of a apping link, and on the primary (master) and
standby management units as KERN-2-INT messages if the apping port belongs to either of these units.
In the following example, a stack-port on the master aps. 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 oending unit.
