    Description

      Hi! I need to change the SNMP community string on many of my devices. The new string is one of the ones that obs knows about, and is tried during discovery of new devices.

      I changed the string on the device, and then left obs running a discover -h all.

      When I came back to it, the device was "down (snmp)". I tried a manual discover -h <devicename> but it said said I specified a device that did not exist.

      Going into the web UI and changing the saved SNMP community allows manual rediscovery again - but it is not wierd that auto-discovery didn't pick up the new community string?

      Many thanks!
