Dear Community,
I would want to ask you if you had similar problem - I configured for monitoring via SNMP two switches - FS. Expect the checks, we would want to receive also SNMP Traps. Here the problem comes - I configured the host, added the community / password into EC’s settings (v2c) and uploaded the MIB files which are related with the version of the switches. There were 2 folders - for standard mibs and ‘private’ which are exactly for the FS switches. First I uploaded the ‘private’ zip file, but a lot of dependencies were missing. I found them into ‘standard’ folder and uploaded also them. The information which was presented into the view which I prepared was not translated by EC and it was shown as OIDs, but I also noticed that other Cisco hosts were ‘broken’ - in place of translated information, OIDs were presented. I deleted one by one the FS mib files and some from the standard which I uploaded earlier, but the problem still exist and the following errors appear inside the log file of EC.
Do you know how can I resolve those problems?
