Static MAC Addresses

The switch has a static MAC address table that stores all the MAC
addresses that it learns from the network. The switch uses this table for
forwarding traffic to specific ports, so it does not broadcast traffic to every
port.
There are two ways to add addresses to the MAC address table:
• The switch can learn addresses from the network and add them
dynamically. Dynamic entries remain in the table only while the
associated node is active, and they are deleted if the node is inactive for
longer than a certain period of time (age-out time).
• You can manually add MAC addresses to the table. These are called
static addresses, because they remain in the table until you remove
them, even if the associated node is inactive or removed from the
network. Performance and security issues are two reasons for adding
static addresses.
To add a static MAC address to the address table
1 Click the Configure Device menu, then click Forwarding and Filtering.
2 Click Static MAC Addresses.
3 Click Add.
4 In the MAC address box, type the MAC address of a device on the
network. Do not include hyphens.
5 In the Port Number box, click a port number.
6 If port-based or tag-based (IEEE 802.1Q) VLANs are set up on the
switch, static MAC addresses are associated with specific VLANs.
Type the VLAN name (port-based VLANs) or VID (tag-based VLANs)
to associate with the MAC address.
7 Click Add.
