4.7.6.2 Static MAC Address
When you add a static MAC address, it remains in the switch's address table, regardless of whether the
device is physically connected to the switch. This saves the switch from having to re-learn a device's
MAC address when the disconnected or powered-off device is active on the network again.
1. MAC Address: enter the MAC address to and from which the port should permanently
forward traffic, regardless of the device network activity.
2. Port Number: select a port number.
3. VLAN ID: If tag-based (IEEE 802.1Q) VLANs are set up on the switch, static addresses are
associated with individual VLANs. Type the VID (tag-based VLANs) to associate with the
MAC address.
4. Click Add button.
5. Use Delete button to delete unwanted MAC address.
