What is expExpressionInstance?

A read-only OBJECT IDENTIFIER recording which particular wildcarded value instance (the expValueInstance) was being computed when the last evaluation error occurred, useful when a wildcarded expression fails for only some of its instances.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.22.1.3.1.1.11
snmpwalk -v2c -c public <target> EXPRESSION-MIB::expExpressionInstance

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.22.1.3.1.1.11.1
snmpget -v2c -c public <target> EXPRESSION-MIB::expExpressionInstance.1
