Removing Front End Port Stacking
To remove the configuration on the front end ports used for stacking, use the following commands.
1. Remove the stack group configuration that is configured.

2. Save the stacking configuration on the ports.
EXEC Privilege mode

After the units are reloaded, the system reboots. The units come up as standalone units after the reboot completes.
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 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.
