If I snmpwalk a 7600 with dual sups with cpmCPUTotal5minRev I get:
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.1 = Gauge32: 1 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.2 = Gauge32: 2 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.3 = Gauge32: 0 percent
I'm assuming I have another cpu on one of the boards. Are they numbered in the order they are in the chassis? If so, it seems odd the redundant sup would have high cpu.
