expNameHighestIndex
Module: EXPRESSION-MIB
OID (symbolic): EXPRESSION-MIB::expNameHighestIndex
OID (numeric): 1.3.6.1.4.1.9.10.22.1.2.2
Node type: OBJECT-TYPE
Type: ExpressionIndexOrZero
Access: read-only
Description: The highest value of ExpressionIndex ever assigned on this system. Preferrably this value is preserved across system reboots. A managed system that is unable to store expressions across reboots need not preserve this value across reboots.
If all expression-creating applications cooperate, they may use this to avoid reusing an ExpressionIndex. To do so, attempt creation of a new entry with this value + 1 as the value of expExpressionIndex.
Although reusing ExpressionIndexes could lead to an application receiving a misunderstood value, it is a matter of local management policy whether to reuse them.
What is expNameHighestIndex?
The highest ExpressionIndex ever assigned on this device; a management application can request this value plus one when creating a new expression to avoid accidentally reusing an old index.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.22.1.2.2 snmpwalk -v2c -c public <target> EXPRESSION-MIB::expNameHighestIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.22.1.2.2.1 snmpget -v2c -c public <target> EXPRESSION-MIB::expNameHighestIndex.1
