Cisco MIB for physical memory

Question

router#show ver

4194304K bytes of physical memory.

Does anyone know the mib for physical memory of a cisco router? Lots of examples of memory used etc.

Edit:

Nothing is easy in cisco land

-sh-4.1$ snmpwalk -v2c -c r2 router 1.3.6.1.4.1.9.9.195.1.1.1.1
SNMPv2-SMI::enterprises.9.9.195.1.1.1.1.7000 = Gauge32: 1845398136

-sh-4.1$ snmpwalk -v2c -c r2 router 1.3.6.1.4.1.9.3.6.6
SNMPv2-SMI::enterprises.9.3.6.6.0 = INTEGER: 790666272

Router# sh ver
4194304K bytes of physical memory.

Both appear to be different?

Answer 1

OLD-CISCO-CHASSIS-MIB::processorRam But that MIB has been deprecated since IOS 12.0.

CISCO-ENTITY-EXT-MIB::ceExtProcessorRam is where they moved it. (7 years later.)

From my 2851:

Cisco 2851 (revision 1.0) with 1032192K/16384K bytes of memory.
CISCO-ENTITY-EXT-MIB::ceExtProcessorRam.3 = Gauge32: 1073741824 bytes
OLD-CISCO-CHASSIS-MIB::processorRam.0 = INTEGER: 1056964608

The entity mib is processor + io memory (all physical ram), and the old chassis mib is showing just the processor memory (as the name suggests)

If the service-engine is configured, then physical memory is partitioned, and it may not be reflected in SNMP.
