Command Modes INTERFACE Command History Usage Information Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module This command and its options are supported on physical interfaces, static LAGs, LACP LAGs, and VLANs. If the vlan option is not specified, the MAC address counters is not VLAN-based. That is, the sum of the addresses learned on all VLANs (not having any learning limit configuration) is counted against the MAC learning limit. MAC learning limit violation logs and actions are not available on a per-VLAN basis. With the no-station-move option, MAC addresses learned through this feature on the selected interface persist on a per-VLAN basis, even if received on another interface. Enabling or disabling this option has no effect on already learned MAC addresses. After the MAC address learning limit is reached, the MAC addresses do not age out unless you add the dynamic option. To clear statistics on MAC address learning, use the clear counters command with the learning-limit parameter. When a channel member is added to a port-channel and there is not enough ACL CAM space, the MAC limit functionality on that port-channel is undefined. When this occurs, un-configure the existing configuration first and then reapply the limit with a lower value.

INTERFACE
Command
History
Usage
Information
This command and its options are supported on physical interfaces, static LAGs, LACP LAGs, and
VLANs.
If the
vlan
option is not specified, the MAC address counters is not VLAN-based. That is, the sum of
the addresses learned on all VLANs (not having any learning limit configuration) is counted against
the MAC learning limit.
MAC learning limit violation logs and actions are not available on a per-VLAN basis.
With
the
no-station-move
option,
MAC addresses learned through this feature on the selected interface
persist
o
n a per-VLAN basis, even if received on another interface. Enabling or disabling this option
has no effect on already learned MAC addresses.
After the MAC address learning limit is reached, the MAC addresses do not age out unless you add the
dynamic
option. To clear statistics on MAC address learning, use the
clear counters
command with the
learning-limit parameter.
When a channel member is added to a port-channel and there is not enough ACL CAM space, the
MAC limit functionality on that port-channel is undefined. When this occurs, un-configure the existing
configuration first and then reapply the limit with a lower value.
