How to Configure Gigabit EtherSwitch EHWICs

Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

Use the clear mac-address-table dynamic command in privileged EXEC mode to remove all dynamic

entries.

Use the show mac-address-table dynamic command in privileged EXEC mode to verify configuration.

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 hw-address interface gi 0/slot/port vlan vlan-id

3. end

DETAILED STEPS

Use the no mac-address-table secure hw-address interface gi 0/slot/port vlan vlan-id command in

global configuration mode to remove a secure address.

To remove all secure addresses, use the clear mac-address-table secure command in privileged EXEC

mode.

Use the show mac-address-table secure command in priviledged EXEC mode to verify configuration.
