Parameter
Description
Aging Time
Synopsis:
15 to 800
Default:
300 s
This parameter configures the time that a learned MAC address is held before being
aged out.
Age Upon Link Loss
Synopsis:
15 to 800
Default:
300 s
When a 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.

Section 5.4.3
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 5.4.3.1, “Viewing a List of Static MAC Addresses”
•
Section 5.4.3.2, “Adding a Static MAC Address”
