What is ipfInIndex?

This integer is the reference index that uniquely identifies each incoming IP filter rule in the ipfInTable, and also serves as the row's index. Administrators use it to correlate a specific inbound filter rule with its matching hit counter and rule text when reviewing firewall activity via SNMP. For example, index 3 would identify the third configured incoming IP filter rule on the device.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.13.2.1.1.1
snmpwalk -v2c -c public <target> UCD-IPFILTER-MIB::ipfInIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.13.2.1.1.1.1
snmpget -v2c -c public <target> UCD-IPFILTER-MIB::ipfInIndex.1
