Setup Guide

mac learning-limit
Limit the maximum number of MAC addresses (static + dynamic) learned on a selected interface.
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 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.
