Beginning in privileged EXEC mode, follow these steps to remove a dynamic
address entry:
Purpose
Enter global configuration mode.
Enter the MAC address to be removed from dynamic MAC
address table.
Return to privileged EXEC mode.
Verify your entry.
You can remove all dynamic entries by using the clear mac-address-table
dynamic command in privileged EXEC mode.
The secure address table contains secure MAC addresses and their associated
ports and VLANs. A secure address is a manually entered unicast address that is
forwarded to only one port per VLAN. If you enter an address that is already
assigned to another port, the switch reassigns the secure address to the new port.
You can enter a secure port address even when the port does not yet belong to a
VLAN. When the port is later assigned to a VLAN, packets destined for that
address are forwarded to the port.
Beginning in privileged EXEC mode, follow these steps to add a secure address:
Purpose
Enter global configuration mode.
Enter the MAC address, its associated port, and the VLAN
ID.
Return to privileged EXEC mode.
