cntifSubIndex
Module: CNTAU-MIB
OID (symbolic): CNTAU-MIB::cntifSubIndex
OID (numeric): 1.3.6.1.4.1.333.1.2.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A value that uniquely indexes an interface in a multiply-interfaced device driver.
What is cntifSubIndex?
This read-only INTEGER is a value that uniquely indexes an interface within a device driver that manages multiple interfaces. An admin working with a driver that fans out to several sub-interfaces would use this sub-index, together with cntifIndex, to identify one specific interface among several handled by the same driver instance. For example, two interfaces sharing the same base driver but different cntifSubIndex values would be distinguished this way when reviewing per-interface statistics.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.1.2.1.1.4 snmpwalk -v2c -c public <target> CNTAU-MIB::cntifSubIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.333.1.2.1.1.4.1 snmpget -v2c -c public <target> CNTAU-MIB::cntifSubIndex.1
