Removing Dynamic Addresses

Beginning in privileged EXEC mode, follow these steps to remove a dynamic address entry.

SUMMARY STEPS

1. configure terminal

2. no mac-address-table dynamic

hw-addr

3. end

DETAILED STEPS

You can remove all dynamic entries by using the clear mac-address-table dynamic command in

privileged EXEC mode.

Verifying Dynamic Addresses

Use the show mac-address-table dynamic command to verify configuration:

Router# show mac-address-table dynamic

Adding Secure Addresses

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.

SUMMARY STEPS

1. configure terminal

2. mac-address-table secure address

hw-addr
