Wired Network Monitoring
Wired Network Monitoring is used to monitor the wired network devices in your Extreme AirDefense
monitored system. Use this screen to generate generate alarms for your wired network by selecting any
of the following conditions:
• New device detected on the wired network - This option is enabled by default. When selected, an
alarm is generated when a new device is detected on the wired side of your Extreme AirDefense
managed network.
Using the Known Vendors button, you can select the wired equipment vendors of devices that are
commonly used in your network. When a device of a vendor found in the list is added to the wired
network, the system will generate an alarm of lower severity than that is normally generated.
• Sanctioned wired device detected at dierent location in tree hierarchy than when originally
discovered - Select this option to generate an alarm when a device has moved to a dierent location
in your Extreme AirDefense tree hierarchy from where it was originally discovered when it was first
added to the system.
• Sanction device no longer observed. - Select this option to generate an alarm when a sanctioned
device is not observed in your wired network. You must specify a minimum time for the device to
have not been seen on your network for this alarm to be generated. Use the Minimum not seen time
control and its associated spinner control to set the time duration.
To detect new devices on your network, existing devices must be classified as sanctioned. Use the Mass
Wired Network Device Classification button to open a dialog where you can sanction all or a selection
of devices at one time. It is recommended that this process should be done when you initially configure
policies or after major network changes.
