None: Do not allow more than Limit MAC addresses on the port, but take no further
action.
Trap: If Limit + 1 MAC addresses is seen on the port, send an SNMP trap. If Aging is
disabled, only one SNMP trap is sent, but with Aging enabled, new SNMP traps are
sent every time the limit gets exceeded.
Shutdown: If Limit + 1 MAC addresses is seen on the port, shut down the port. This
implies that all secured MAC addresses are removed from the port, and no new
address are learned. Even if the link is physically disconnected and reconnected on
the port (by disconnecting the cable), the port remains shut down.
There are three ways to re-open the port:
1. Reboot the switch,
2. Disable and re-enable Limit Control on the port or the MP1204-XT,
3. Click the Reopen button.
Trap & Shutdown: If Limit + 1 MAC addresses is seen on the port, both the Trap and
the Shutdown actions described above are taken.
Disabled: Limit Control is either globally disabled or disabled on the port.
Ready: The limit is not yet reached. This can be shown for all actions.
Limit Reached: Indicates that the limit is reached on this port. This state can only be
shown if the Action is set to None or Trap.
Shutdown: Indicates that the port is shut down by the Limit Control module. This
state can only be shown if Action is set to Shutdown or Trap & Shutdown.
