What platform is the device? Are the primary and standby devices the
same - platform, SW, config, traffic?
During the spike, is the CPU consumed at interrupt or process level?
Grab and send over sh proc cpu, sh align, sh int stat, sh log (if
device is too unresponsive during failover, have onsite personnel pull
out traffic-laden cables one by one until device is responsive, grab
captures before reinserting cable/s).

PS. Disable console logging

Hi All,
Just wondering if I can get some advice. We have two routers in a
HSRP active/standby pair. If ones reloads then the CPU on the other
hits 100% and crashes. The only way we can recover this is for a
field engineer to pull all the Ethernet cables out and then, when
system is calm, repatch them. We access the device via VTY so
struggling to actually get any commands in to troubleshoot as per
the Cisco 'Troubleshooting High CPU Utilization' doc as the CPU
spikes .
Any advice on best way to progress this?
Regards, David
