pfIfIndex

Module: OPENBSD-PF-MIB

OID (symbolic): OPENBSD-PF-MIB::pfIfIndex

OID (numeric): 1.3.6.1.4.1.30155.1.8.128.1.1

Node type: OBJECT-TYPE

Description: A unique value, greater than zero, for each interface. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization.

What is pfIfIndex?

A unique integer identifying each row of the pfIfTable, used as that table's SNMP index. It's a stable per-interface handle, not a meaningful metric on its own, but needed to correlate all the other pfIf* counters that belong to the same interface.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.30155.1.8.128.1.1
snmpwalk -v2c -c public <target> OPENBSD-PF-MIB::pfIfIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.30155.1.8.128.1.1.1
snmpget -v2c -c public <target> OPENBSD-PF-MIB::pfIfIndex.1
