To display the PE ports that are shut down due to loop detection, enter the show mac
learning-limit violate-action command.
Dell# show mac learning-limit violate-action

To display the reason why the line protocol is down on a PE port or port channel, enter
the show interface command.
Dell(conf-if-po-1)#do show interface port-channel 1
Port-channel 1 is up, line protocol is down(Pe Loop Detection)
When a PE interface is shut down due to a PE loop violation, you must manually reset it.
To reset the interface, shut it down by entering the shutdown command and then re-
enable it by entering the no shutdown command.

learned on the interface. The range is from 1 to 1000000.
E-Series only: Enter the keyword then the VLAN ID. The range is
from 1 to 4094.
(OPTIONAL) Enter the keyword dynamic to allow aging of MACs
even though a learning limit is configured.
(OPTIONAL) Enter the keywords station-move to allow a
station move on learned MAC addresses.
• On S-Series, the default behavior is dynamic.
NOTE: "Static" means manually entered addresses, which do not age.
