Description: The index used by this table.

What is ibmSystemPhysicalMemoryKeyIndex?

This object holds the unique key value used to index each row of the physical memory table, identifying one memory bank or module recognized by the operating system. Admins and monitoring tools use it internally to correlate the various per-module attributes, such as capacity, status, and serial number, back to a specific physical memory device. For example, a system with four DIMM slots might expose key index values like 'DIMM0', 'DIMM1', 'DIMM2', 'DIMM3' to distinguish each row.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.6.159.1.1.120.1.1.1
snmpwalk -v2c -c public <target> IBM-SYSTEM-MEMORY-MIB::ibmSystemPhysicalMemoryKeyIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.6.159.1.1.120.1.1.1.1
snmpget -v2c -c public <target> IBM-SYSTEM-MEMORY-MIB::ibmSystemPhysicalMemoryKeyIndex.1
