Trap
: If Limit + 1 MAC addresses is seen on the port, send an SNMP trap. If
Aging is disabled, only one SNMP trap will be sent, but with Aging enabled,
new SNMP traps will be sent everytime 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 will be removed from the
port, and no new will be learned. Even if the link is physically disconnected
and reconnected on the port (by disconnecting the cable), the port will
remain shut down. There are three ways to
re-open
the port:
1) Boot the stack or elect a new masterthe switch,
2) Disable and re-enable Limit Control on the port or the switch,
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 will be taken.
State
This column shows the current state of the port as seen from the Limit Control's
point of view. The state takes one of four values:
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 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
.
Re-open Button
If a port is shutdown by this module, you may reopen it by clicking this button,
which will only be enabled if this is the case. For other methods, refer to
Shutdown
in the Action section.
Note, that clicking the reopen button causes the Page to be refreshed, so
non-committed changes will be lost.
