Port Intrusions.
Occurs when a MAC address detected from an incoming
packet on a port does not match the authorized MAC address for the port. Port
intrusions are controlled by the entries you make in the Port Security dialog
box in ASA or the Browser Interface. Port intrusions are shown at the bottom
of the Hub Console Interface screen in tabular form. Port intrusions are
differentiated from manager intrusions in the Browser Interface in two ways.
•
the number of the port to which the unauthorized manager attempted
to connect is displayed in the Port column.
•
a MAC address is displayed in the Intruder Address column.
Note that you cannot clear the log of entries. The Intruder Log can display up
to 20 entries. Entries are displayed in the log for the life of the hub until more
than 20 are recorded. When new entries are received after 20 have been
recorded, existing entries are removed to maintain a maximum entry count of
20. Entries are removed on the basis of age, the oldest entry being removed
first, the second oldest entry removed next, and so on.
The information shown in the Intruder Log is as follows.
Violation Time
(Console only). Indicates the amount of time that has
elapsed since the hub was powered on in the format DD, HH:MM:SS.
Port.
The port number that is reporting attempted access by an unautho-
rized device. Settings can be:
•
Port number for a port intrusion
•
SNMP Agent
for a manager intrusion
Intruder Address
(
Violator’s Address
in Console). The address of the
unauthorized device.
•
IP Address for a manager intrusion
•
MAC address for a port intrusion
Time
(Violation Time in Console). The date and time in the format
DD:MM:YY HH:MM:SS. The console also contains the violation time in the
number of days. This value is the system up time when an intruder was
detected.
Clear Intrusion Log Fault LED.
(Browser Interface only). Stops LEDs
of ports reporting port intrusions from flashing.
