The Switch also provides the function of MAC address aging. If the Switch receives no
packet for a period of time, it will delete the related entry from the MAC address
table. However, this function takes no effect on the static MAC addresses.
You can configure (add or modify) the MAC address entries manually according to the
actual networking environment. The entries can be static ones or dynamic ones.
MAC address table management includes:
