9.2 Configuring MAC Address Learning Options

Figure 144: MAC Address Learning Options Form

Aging Time

Synopsis: 15 to 800

Default: 300 s

This parameter configures the time a learned MAC address is held before being aged out.

Age Upon Link Loss

Synopsis: { No, Yes }

Default: Yes

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 to age-out all MAC addresses learned on a failed port immediately upon link failure detection.

9.3 Configuring Static MAC Address Table

Static MAC addresses are usually configured when the user wishes to enforce port security (if supported).

Static MAC addresses are also configured when a device can receive but cannot transmit frames.

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.
