As of LCOS 9.00 you have the option of changing the default port for the SNMP service from port 161.
Enter the respective port in LANmonitor, for example, when adding a new device. You also have the option of configuring new devices by entering IP addresses and the SNMP port when executing the program. To do this, start the LANmonitor with the syntax lanmon /add:[<IPv6-Address>]:<Port>, for example, lanmon /add:[fe80::2a0:57ff:fe1b:3302]:161.
