3. Configure the following parameter(s) as required:
Parameter Description
MAC Aging Time (sec) Default: 300
The time a learned MAC address is held before being aged out.
MAC Age on Loss Default: true
When link failure (and potentially a topology change) occurs, the switch may have some
MAC addresses previously learned on the failed port. As long as those addresses are
not aged-out, the switch will still be forwarding traffic to that port, thus preventing that
traffic from reaching its destination via the new network topology. This parameter allows
the aging-out of all MAC addresses learned on a failed port immediately upon link failure
detection.
4. Click Commit to save the changes or click Revert All to abort. A confirmation dialog box appears. Click OK
to proceed.
5. Click Exit Transaction or continue making changes.
Section 5.33.4
Managing Static MAC Addresses
Static MAC addresses must be configured when the device is only able to receive frames, not transmit them.
They may also need to be configured if port security (if supported) must be enforced.
Prioritized MAC addresses are configured when traffic to or from a specific device on a LAN segment is to be
assigned a higher CoS priority than other devices on that LAN segment.
The following sections describe how to configure and manage static MAC addresses:
• Section 5.33.4.1, “Viewing a List of Static MAC Addresses”
• Section 5.33.4.2, “Adding a Static MAC Address”
• Section 5.33.4.3, “Deleting a Static MAC Address”
