Description: The registry slot of a mibmodule.
What is mrIndex?
This OID is the registry slot (an OID value) identifying one entry in the table of MIB modules the agent has loaded. An admin walking this table can see which sub-agent modules are compiled into a given net-snmp installation, alongside mrModuleName for the human-readable name.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.102.1.1 snmpwalk -v2c -c public <target> UCD-SNMP-MIB::mrIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.102.1.1.1 snmpget -v2c -c public <target> UCD-SNMP-MIB::mrIndex.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> mrIndex.1
