14.3.14 ICMP Connectivity Checking
The Barracuda NG Access Monitor supports the usage of ICMP to check if the configured Access
Control Server is available. The use of this option highly recommended because it avoids long
timeouts, thus is enabled by default.
14.3.15 Resetting the 802.1X Authentication process
If, for which reason whatsoever, it is required to restart the 802.1X authentication process, the
Barracuda NG Access Monitor provides the necessary functionality. In order to perform this you should
follow these steps:
• Enter the Port Security section in the Barracuda NG Access Monitor
• Selected the network interface to reset
• Choose "Reset" from the tasks menu on the left or through the context menu
of the network interface
Once done, the session password will be reset and the 802.1X authentication process starts over.
This value may also be changed by using the Advanced Settings screen within the Barracuda NG Access Monitor.
The value configured on the Access Control Server overwrites the value configured on the client computer.
