I am trying use SNMP to get MemoryUsed and MemoryFree from SUP720-3B SP. Is there a particular OID that can be used to get this information? 



I've OIDs which work for RP but the OIDs for SP seem to be different for each 6509-E chassis. 



For example, I walked three 6509-Es with Sup720-3B, installed in slot 5 and resulting OID is different on each chassis. 



Sup720-3B in slot 5, running 12.2(33)SXI 

snmpwalk -v1 -c irishspring test -dist-01 1.3.6.1.4.1.9.9.221.1.1.1.1.7 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.5001.1 = Gauge32: 127996892 (SP Processor Mem) 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.5001.2 = Gauge32: 2082350 4 (SP IO Mem) 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.5017.1 = Gauge32: 121830752 (RP Processor Mem) 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.5017.2 = Gauge32: 21605592 (R P IO Mem) 




Sup720-3B in slot 5, running 12.2(18)SXF10 
snmpwalk -v1 -c irishspring test -dist-02 1.3.6.1.4.1.9.9.221.1.1.1.1.7

snmpwalk -v1 -c irishspring test -dist-03 1.3.6.1.4.1.9.9.221.1.1.1.1.7 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.6001.1 = Gauge32: 128474820 (SP Processor Mem) 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.6001.2 = Gauge32: 20823504 (SP IO Mem) 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.6017.1 = Gauge32: 141062428 (RP Processor Mem) 
CISCO-ENHANCED-MEMPOOL-MIB::cempMemPoolUsed.6017.2 = Gauge32: 21605592 (RP IO Mem) 



Above OIDs also change upon reboot. Is there an easier method or different OID to get memory information on SP? 



Thanks in advance.
