Module: CMC-MIB

OID (symbolic): CMC-MIB::ipxSysInstance

OID (numeric): 1.3.6.1.4.1.44.2.1.5.1.1.1.1.1

Node type: OBJECT-TYPE

What is ipxSysInstance?

This INTEGER uniquely identifies an instance of the IPX protocol running on the system, and is only writable when creating a new table entry. An admin sets this when a device supports multiple IPX instances and needs to distinguish between them. For example, an operator configuring a router that runs IPX on more than one logical network would assign each instance a distinct ipxSysInstance value when creating its table entry.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.44.2.1.5.1.1.1.1.1
snmpwalk -v2c -c public <target> CMC-MIB::ipxSysInstance

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.44.2.1.5.1.1.1.1.1.1
snmpget -v2c -c public <target> CMC-MIB::ipxSysInstance.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.44.2.1.5.1.1.1.1.1.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ipxSysInstance.1
