MAC Addresses Window
This window appears when you choose Administration > MAC Addresses on
the menu bar. You can also click here
to launch it. Use it to:
When you finish with the window, click OK.
To change the aging time for addresses:
- Click the Dynamic Address tab of the MAC Addresses window.
- In the Aging Time field, enter a number from 10 to 1000000 (seconds;
about 11.5 days).
The aging interval applies to all switch VLANs. The default is 300 seconds.
Note: Setting too short an aging time can cause addresses
to be prematurely removed from the table. Then when the switch receives a
packet for an unknown destination, it floods the packet to all ports in the
same VLAN as the receiving port. This unnecessary flooding can impact performance.
Setting too long an aging time can cause the address table to be filled with
unused addresses; it can cause delays when a workstation is moved to a new
port.
- Click OK to put your changes in effect and to close the
MAC Addresses window.
To clear the table, click Clear All.

To add a static address:

Note: By default, an EtherChannel (EC) port group forwards
packets based on its source address. For the default source-based port groups,
configure the static address to forward to all ports in the port group to
avoid losing packets. For destination-based port groups, configure the address
to forward to only one port in the group to avoid transmitting duplicate packets.
To modify a static address:
