Cisco how to check interface index using snmp
Try command
$ snmpwalk -v2c -c community-string HOST 1.3.6.1.2.1.31.1.1.1.1
Outcome will be:
IF-MIB::ifName.1 = STRING: Fa0
IF-MIB::ifName.2 = STRING: Fa1
This -^- is the interface-number
so when using for example nagios plugin check_itraffic use this number as interface parameter
