Configuring a Static MAC AddressA static entry is one that is not subject to aging. Enter static entries manually.To create a static MAC address entry, use the following command.• Create a static MAC address entry in the MAC address table.CONFIGURATION modemac-address-table staticDisplaying the MAC Address TableTo display the MAC address table, use the following command.• Display the contents of the MAC address table.EXEC Privilege modeshow mac-address-table [address | aging-time [vlan vlan-id]| count | dynamic | interface |static | vlan]• address: displays the specified entry.• aging-time: displays the configured aging-time.• count: displays the number of dynamic and static entries for all VLANs, and the total number of entries.• dynamic: displays only dynamic entries.• interface: displays only entries for the specified interface.• static: displays only static entries.• vlan: displays only entries for the specified VLAN.MAC Learning LimitMAC address learning limit is a method of port security on Layer 2 port-channel and physical interfaces, and VLANs. It allows you to set anupper limit on the number of MAC addresses that learned on an interface/VLAN. After the limit is reached, the system drops all traffic froma device with an unlearned MAC address.This section describes the following:• Setting the MAC Learning Limit• mac learning-limit Dynamic• mac learning-limit mac-address-sticky• mac learning-limit station-move• Learning Limit Violation Actions• Setting Station Move Violation Actions• Recovering from Learning Limit and Station Move ViolationsDell Networking OS Behavior: When configuring the MAC learning limit on a port or VLAN, the configuration is accepted (becomes partof running-config and show mac learning-limit interface) before the system verifies that sufficient CAM space exists.
