Aging Time

You can configure the aging time for MAC addresses, to realize the dynamic address aging function. The MAC addresses that do not appear again in the transport network in the duration of the aging time are regarded as having no route requirements. The MAC addresses are deleted from the MAC address table, so that the MAC address table can contain more MAC addresses. In this user interface, you can set the life cycle for filtering dynamic records in the database and the aging time for the MAC address.

Navigation Path

In the NE Explorer, click the board and select Configuration > Layer-2 Switching Management > Aging Time from the Function Tree.

Guideline

If the aging time is too long, the MAC address table may save many outdated MAC address items. This may use up the resources of the MAC address table. As a result, the MAC address table may not be updated according to the change in the network.
If the aging time is too short, the effective MAC address items may be deleted. As a result, packets that are broadcasted cannot find the destination MAC address and the performance of the network is affected.
