Dell Force10 Z9000 - Mac Learning-Limit Learn-Limit-Violation

Version 6.5.1.0 Added support for MAC Learning-Limit on the LAG.
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 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 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.
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.
