You can remove the following types of learned MAC address entries from the system MAC address table:
- All MAC address entries
- All MAC address entries for a specified Ethernet port
- All MAC address entries for a specified VLAN
- A specified MAC address entry in all VLANs
For example, to remove entries for the MAC address 00-00-00 in all VLANs, enter the following command at the privileged EXEC level of the CLI.
