Scalar MIBs represent a single object instance whereas tabular MIBs define multiple related object instances grouped together in MIB tables. If you're using the same MIBS over and over again, this gets annoying. To run the SNMP walk we need to add a new SNMP polling service check or to edit an existing one. But unlike most of the other command-line tools, it can only work with a single starting OID. Place the FCMGMT-MIB file in that directory Inside that directory, create a file called snmp.conf which contains the following lines: mibdirs +$HOME/.snmp mibs +FCMGMT-MIB Of course you can specify multiple mibdirs and/or multiple mibs. interface-set snmp index.

When manager (me) issues either snmpwalk or snmpget requests regarding to SV_Network.mib the agent returns all values expected but when I request an OID from SV_Service.mib I get problems (both SV_Network.mib and SV_Service.mib are stored in the same directory). This article explains how to run both utilities. Moreover, SnmpWalk allows you to use a simple version of SNMPv1/SNMPv2c and also supports a safe version of SNMPv3.
