Reference Guide

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.

Usage
Information
This command and its options are supported on physical interfaces, static LAGs, LACP LAGs,
and VLANs.
If you do not specify the vlan option, the MAC address counters are 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 keyword 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.
NOTE: If you configure this command on an interface in a routed VLAN, and after the MAC
addresses learned reaches the limit set in the mac learning-limit command, IP
protocols are affected. For example, VRRP sets multiple VRRP Masters and OSPF may not
come up.
