What is ipxCircSysInstance?

This is the unique identifier of the IPX protocol instance that a given row in the circuit table belongs to, and it can only be set when the row is first created. It lets a device running multiple IPX instances associate each circuit with the correct instance. For example, on a router running two separate IPX instances, this value distinguishes which instance owns a particular circuit entry.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.44.2.1.5.1.2.1.1.1
snmpwalk -v2c -c public <target> CMC-MIB::ipxCircSysInstance

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.44.2.1.5.1.2.1.1.1.1
snmpget -v2c -c public <target> CMC-MIB::ipxCircSysInstance.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.44.2.1.5.1.2.1.1.1.1 i <value>
