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.
MAC Limit Configuration
The Layer 2 MAC Limit function can be per-port configured for security
management purposes. When the port is in MAC Limit mode, the port will be
"locked" without permission of address learning. Only the incoming packets with
Source MAC already existing in the address table can be forwarded normally.
User can disable the port from learning any new MAC addresses.
