MAC Address Table Management 307
Figure 76 The Switch Forwards Packets with MAC Address Table
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.
