The switch will learn Mac addresses to an ARL table automatically. And follow

the table to do packet store-and-forward operation. If Mac addresses are not

received for some time, those Mac addresses will be removed from the table.

This operation is called aging.

The aging operation could be disable here. And all the learned Mac addresses

will not be removed from the ARL table.

And the time for aging operation could be modified here. It is 300 seconds by

default.
