6.8 MAC limit
MAC limit allows users to set a maximum number of MAC addresses to be stored in the MAC address table. The MAC
addresses chosen to be stored in MAC address table is the result of first-come-first-save policy. Once a MAC address is stored
in the MAC address table, it stays in until it is aged out. When an “opening” is available, the switch stored the first new MAC
address it sees in that opening. All packets from MAC addresses not in the MAC address table should be blocked.
User can configure the MAC limit setting and fill in the new value.
