I am trying to add the Switch. But could not add and discover the switch. The router already adds with External IP address to the system. I want to add the switch to libreNMS. I can access Switch remotely with external IP with Port number. 126.96.36.199:3362.
The switch location is the other side of town.
So lets asume u added your router via SNMP:
188.8.131.52 on port 161 (SNMP)
u need = DNS *.yourclientdomain.net (A Record to 184.108.40.206)
Add your router as CR01.yourclientdomain.net port 161 ( SNMP )
now add your switch SW01.yourclientdomain.net port 1610 (example for SNMP)
U need to open port 1610 (in this example) to your internal switch to 161 ( or 1610) depens where SNMP listen to ( port open or port forward )
Now u got CR01… and SW01 … in your libre NMS ( I asume the hostname is difrent then the switch )
Be aware SNMPv2c = plain text / i sugest u move to SNMP v3 incl encription.
