When you configure the settings for a LAN Enforcer you specify the following listening ports:
The listing port that is used for communication between the VLAN switch and the LAN Enforcer.
The VLAN switch sends the RADIUS packet to the UDP port.
The listening port that is used for communication between the LAN Enforcer and a RADIUS server.
You specify this port when you specify a RADIUS server.
If the RADIUS server is installed on the management server, it should not be configured to use port 1812. The RADIUS servers are configured to use port 1812 as the default setting. Because the management server also uses port 1812 to communicate with the LAN Enforcer, there is a conflict.
To specify a listening port that is used for communication between a VLAN switch and a LAN Enforcer
In the Symantec Endpoint Protection Manager Console, click Admin.
Under Servers, select the Enforcer group.
Under Tasks, click Edit Group Properties.
In the LAN Enforcer Settings dialog box, on the General tab, type the number of the UDP port that you want to assign in the Listen port field.
The default setting for the port is 1812. The range extends from 1 through 65535.
