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.
