Description
First Heard
The device learns the address of the device attached to the port and
makes it the authorized MAC address. If a different device is later
attached to the port, the new address is registered as an "intruder
address"; a security violation has occurred and the port is
automatically disabled.
Assigned
Enter the address of the device that is authorized to be attached to
the port. If a different device is attached to the port, the new address
is registered as an "intruder address"; a security violation has
occurred and the port is disabled.
To set the Address Selection:
1.
Click on the Set Security Policy for Selected Ports button.
2.
Select a setting from the Address Selection drop down list.
3.
Click on Apply Settings.
Authorized Address
The Authorized Address field contains the MAC address of the device that is
authorized to be attached to the port.
Eavesdrop Prevention
Eavesdrop Prevention is a feature of several HP devices that stops a
computer or other device from seeing network traffic that is not intended for
that port. When Eavesdrop Prevention is configured on a port, the port's
authorized MAC address is compared with the destination address of any
outbound packets.
Set the Eavesdrop Prevention parameter for a port or group of ports by
clicking on the Set Security Policy for Selected Ports button and selecting
"yes" from the Prevent Eavesdropping drop down list.
Send Alarm
If you set the Send Alarm parameter to "yes", a trap will be sent to the
management station when an unrecognized address is received. Set the Send
Alarm parameter for a port or group of ports by clicking on the Set Security
Policy for Selected Ports button and selecting "yes" from the Send Alarm
drop down list.
