During snmpwalk on conductor, customers may see this SNMP message.
Reason: (genError) A general failure occured
Failed object: IF-MIB::ifNumber.0) on the conductor
During snmpwalk on conductor, you are seeing this SNMP message and the reason is as follows.
Interfaces on a conductor are non-forwarding interfaces. Conductor being a management platform, there will be no "forwarding" interfaces like WAN, MPLS, LAN etc on a conductor. Currently the 128T MIBs can only be used for monitoring "forwarding" interfaces. Only on routers there will be forwarding interfaces and we will not see these messages on Routers.
With the command "snmpwalk -v 2c -c <community> <IPaddress-of-conductor>" we are querying all the OIDs in the MIB and this includes OIDs for forwarding interfaces as well. Because there are no forwarding interfaces on conductor, we see the error during the query. In conductors there will be no forwarding interfaces (like WAN, MPLS, LAN etc)
