expExpressionPrefix
Module: EXPRESSION-MIB
OID (symbolic): EXPRESSION-MIB::expExpressionPrefix
OID (numeric): 1.3.6.1.4.1.9.10.22.1.3.1.1.6
Node type: OBJECT-TYPE
Type: OBJECT IDENTIFIER
Access: read-only
Description: An object prefix to assist an application in determining the instance indexing to use in expValueTable, relieving the application of the need to scan the expObjectTable to determine such a prefix.
See expObjectTable for information on wildcarded objects.
If the expValueInstance portion of the value OID may be treated as a scalar (that is, normally, 0) the value of expExpressionPrefix is zero length, that is, no OID at all.
Otherwise expExpressionPrefix is the value of any wildcarded instance of expObjectID for the expression. This is sufficient as the remainder, that is, the instance fragment relevant to instancing the values must be the same for all wildcarded objects in the expression.
What is expExpressionPrefix?
A read-only OBJECT IDENTIFIER giving an application a shortcut OID prefix for interpreting the instance portion of rows in expValueTable, sparing it from having to scan expObjectTable to work out the wildcard indexing.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.22.1.3.1.1.6 snmpwalk -v2c -c public <target> EXPRESSION-MIB::expExpressionPrefix
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.22.1.3.1.1.6.1 snmpget -v2c -c public <target> EXPRESSION-MIB::expExpressionPrefix.1
