this field. The ingressing frames originated by the intruder will be
blocked and the
Security Status
field will display “Intruder”.
If
Enable Alert
is
checked
, the intrusion event is treated as an alarm
(“Intruder” is displayed on red background, ALARM LED is flashing)
and reported to NMS. When the intruder MAC disappears, the alarm
will remain latched for 20 sec. By right-clicking on the intruder MAC
address and selecting
Acknowledge
, the user clears the displayed
intruder MAC address.
If
Enable Alert
is
unchecked
, the intrusion event is not treated as an
alarm (“Intruder” is displayed in black letters on grey background) and
therefore not reported to NMS. When the intruder MAC disappears,
the Intruder message will be displayed for another 20 sec. By right-
clicking on the intruder MAC address and selecting
Acknowledge
, the
user clears the displayed intruder MAC address.
Note:
This field is functional only if the MAC Security field is set to
“Secured” and the „Intrusion Detect‟ checkbox is checked.
Note:
If there are multiple intruder MACs detected, only the one
detected last will be displayed.
Note:
The ingressing frames originated by the intruder are blocked.
Any egressing frames destined for the intruder would not be blocked.

applies to all MAC entries learned from this port.
Note:
The MAC address table entries associated with
a port in „No Blocking‟ mode may include both
dynamic (learned) and static MAC addresses (see
„Static MAC Table Setup‟ in the MAC tab). The „Limit‟
and „MAC Aging Time‟ settings do not apply to static
entries.
Secured
MAC address learning for the port is disabled. Any
ingressing frames originated by the devices whose
MAC addresses have been neither previously learned
