Dell S3100 EMC Command Line Reference Guide for the Series 9.14.2.5 - Page 860

Version 8.3.1.0 8.2.1.0 7.7.1.0 6.5.1.0 Description Added the vlan option on the E-Series. Introduced on the S-Series. Introduced on the C-Series. Added the station-move option. 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 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. 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. Related Commands • mac learning-limit mac-address-sticky - replace deprecated no-station-move parameter. • show mac learning-limit - display MAC learning-limit configuration. mac learning-limit learn-limit-violation Configure an action for a MAC address learning-limit violation. Syntax Parameters mac learning-limit learn-limit-violation {log | shutdown} To return to the default, use the no mac learning-limit learn-limit-violation {log | shutdown} command. log shutdown Enter the keyword log to generate a syslog message on a learning-limit violation. Enter the keyword shutdown to shut down the port on a learning-limit violation. Defaults None Command Modes INTERFACE (conf-if-interface-slot/port) Command History This guide is platform-specific.
