hi,
i have a 7206 g1 router in which we installed:
disk2:c7200-js-mz.124-13a.bin
since that time the cpu util is about 10-15 percent higher than before.
if i do a "sh proc cp sort" there is always "IP SLA Mon Event" one of the top.
i removed all SAA/SLA Pings - and responder - but even then i always see
"IP SLA Mon Event" on the top
CPU utilization for five seconds: 30%/27%; one minute: 34%; five minutes: 31%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
209 15756 69889523 0 0.49% 0.47% 0.49% 0 IP SLA Mon Event

Hi,
This could be a problem with CEF.
That is packects gets process swithced rather than CEF/Fast swithced.
Do you get any messages in you log ?
Try : c7200-js-mz.124-13b.bin 256/48

hi,
thanks for answer, but:
why do you mean its a problem with cef?
cef is enabled.
in my opinion it is strange that always "IP SLA" is on top - and i removed all config from that process!
i mean 35 to 45 % of cpu is not really bad, but it is very strange that it is in fact 10 to 15% higerh than before the upgrade to 12.4.
and the second thing is that i always have the "IP SLA" entry in the cpu list although i have no config of that.
the only log entry:
Jun 3 08:39:05.824: %FIB-4-FIBBADSNMPPREFIX: Invalid prefix passed to CEF SNMP walker (0.0.0.1/0). -Traceback= 0x60635014 0x6146AC74 0x60B80BF4 0x60B811D4 0x60F0E15C 0x60F11E0C 0x60F02FC4 0x60F2B948 0x607324E0 0x607324C4

Hi,
The reason why this could be CEF is that
there is some known bugs related to CEF ,
packets require more CPU if their not CEF switched. So try bug toolkit on CCO or create a TAC case.
