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.
mac learning-limit
Limit the maximum number of MAC addresses (static + dynamic) learned on a selected interface.
C9000 Series
Syntax
mac learning-limit address_limit [vlan vlan-id] [station-move-violation
[dynamic]] [dynamic [no-station-move| station-move]]
Parameters
address_limit Enter the maximum number of MAC addresses that can be learned on the interface. The
range is from 1 to 1000000.
vlan vlan-id E-Series only: Enter the keyword then the VLAN ID. The range is from 1 to 4094.
dynamic (OPTIONAL) Enter the keyword dynamic to allow aging of MACs even though a
learning limit is configured.
station-move-
violation
(OPTIONAL) Enter the keywords station-move to allow a station move on learned
MAC addresses.
Defaults
• On S-Series, the default behavior is dynamic.
NOTE: “Static” means manually entered addresses, which do not age.
