This looks to be an issue with the mib on the device. For example, in the interfaces mib, when trying to query the interfaces mib using MIB Tools, we get the following error:
"Query from interfaces failed. Unable to send SNMP Request
The reason for the error is following entries in the interfaces mib on the device:
126.96.36.199.188.8.131.52.1.23.1 , NULL , NULL
184.108.40.206.220.127.116.11.1.23.2 , NULL , NULL
18.104.22.168.22.214.171.124.1.23.3 , NULL , NULL
126.96.36.199.188.8.131.52.1.23.4 , NULL , NULL
184.108.40.206.220.127.116.11.1.23.5 , NULL , NULL
18.104.22.168.22.214.171.124.1.23.6 , NULL , NULL
126.96.36.199.188.8.131.52.1.23.7 , NULL , NULL
184.108.40.206.220.127.116.11.1.23.8 , NULL , NULL
As per RFC1213-MIB, the IF table with reference to '18.104.22.168.22.214.171.124.1.23' OID does NOT exist. Please refer to the below RFC mibs. http://www.oidview.com/mibs/0/RFC1213-MIB.html http://cric.grenoble.cnrs.fr/Administrateurs/Outils/MIBS/?module=RFC1213-MIB&fournisseur=ietf
If we remove these entries from the walk file and recreate the simulation without these entries, there are no issues.
There are several other places in the mib where we are seeing similar issues of mib oids that do not exist in the RFC and mib definitions according to the published mibs.
The NRM_CPUUtil and NRM_MEMUtil attributes may not be pointing to the correct OID. NRM_CPUUtilAttr needs to be set to 0x5b10088 - fgSysCpuUsageNRM_MEMUtilAttr needs to be set to 0x5b10089 - fgSysMemUsage
