How to Configure EtherSwitch HWICs
100
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.
Follow these steps to add a secure address.
