Issue adding Router - SNMP output

Post by cdavidson »

Here is the output of my SNMP of my Router. I keep getting an error that ...

Bandwidth and Port Status
No ports were detected on the switch. Possible reasons for this include:

The switch is currently down
The switch does not exist at the address you specified
SNMP support on the switch is disabled


None of these are true. I have setup the SNMP on the device just like others on the same subnet.

Can you run this from the CLI on you XI server and get output?

Code: Select all

snmpwalk -v2c -c 'MTR' 172.16.100.1 IF-MIB::ifName

I get ...

Timeout: No Response from 172.16.100.1

I can ping this IP address. Maybe I need to contact my vendor.

Sounds like it, a timeout usually indicates the switch either isn't listening for SNMP traffic or you have an incorrect community string

I got it. The VPN tunnel wasn't allowing SNMP traffic. So I checked the box and now it is working. This is weird because I have another switch over the VPN that was allowing SNMP and I got it before the update.
