Upgrading IOS XR is pretty simple – add packages, activate them, commit new version and upgrade FPD on line cards if necessary. It seems so not all components were upgraded during this process. Everything went smooth but one component were left on every line card – rommonA

With IOS 15.1(3)T for ISR G2 comes quite a change when in comes how communication between SM, ISM and SM-ES modules occurs. Without Multi Gigabit Fabric (MGF) all communication between devices within a router involves the CPU. With MGF modules can communicate with each other without involving the router CPU.

SNMP on IOS XR is not documented at all right now in my opinion. Of course IOS XR supports standard base of MIB’s but if you want to monitor something platform specific it’s hard to guess which MIB you should use. SNMP Object Navigator on cisco.com does not know yet, there is such think as IOS XR or NX-OS.
I got this information from Cisco representative and I’m putting it here so you can use this too. I had to implement CPU usage monitoring on IOS XR for my customer, but unfortunately standard MIB’s were not working. On IOS XR you have to use cpmCPUTotalTable defined in CISCO-PROCESS-MIB
cpmCPUTotalIndex .1.3.6.1.4.1.9.9.109.1.1.1.1.1 cpmCPUTotalPhysicalIndex .1.3.6.1.4.1.9.9.109.1.1.1.1.2 cpmCPUTotal1minRev .1.3.6.1.4.1.9.9.109.1.1.1.1.7 cpmCPUTotal5minRev .1.3.6.1.4.1.9.9.109.1.1.1.1.8
cpmCPUTotalIndex is a unique value to identify each CPU but this is not fixed value. Then you need to check an entity with cpmCPUTotalPhysicalIndex as entPhysicalIndex.
Update: Same MIBs can be used to monitor supervisor usage on Nexus 7000
