Mac Limit; Mac Limit Configuration - Interlogix GE-DS Series User Manual

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.
