No IPv4 data from WS-C3850-12S

Tags: #<Tag:0x00007fe223710590>


Hi, loving LibreNMS but having trouble with one particular device - a Cisco WS-C3850-12S. All my other Cisco switches report their IPv4 traffic stats back to LibreNMS except for this one. I spent some time looking at MIB but that doesn’t seem to be the right direction to go based on warnings and whatnot.

Any recommendations are greatly appreciated.

Hey, I’m wondering if your issue may already be resolved by my PR:

The "" between ‘udp:HOSTNAME:161’ and the first OID in the SNMPGET command in your poller debug is very similar. It looks like you’re on stable releases so even though this was merged you probably won’t get it until the end of the month unless you manually apply or switch to the dev releases.


Cool, thanks for the info. I’ll hang out until I see the next patch become available and give it a try. Will report back later. Thanks!
