hello guyes
I have a problem about C-7513 Slave RSP high CPU utilization
I've configured for redundancy RSP configuration(SSO, RPR+ )
Router operated correctly.
But I can find HIgh CPU utiliztion on slave RSP(Standby) by 'IPC Slave CBus Process'
Active RSP CPU utilization is normal(0%).
So I want to fix this problem. but i can't find any solution.
somebody help me.
here is what i tried
1) changied IOS version,
- current IOS Version is RSP-K91PV-M Version 12.2(25)S15,
and I tried 12.4.23 (SP/VIP), 12.3.26(SP/VIP)
2) changeed redundancy mode
- RPR+, SSO(SSO mode supports only 12.2(25)S15 release
current RPR+ mode.
3) swaped RSP module
- swaped slot 6 with slot 7 (both are RSP 8)
here is slave RSP output.

Hello ChangShik,
first of all verify that you have only VIP linecards in the chassis and no old cpuless Interface processors
see
RPR+ operates only in a system with VIPs as the line cards. Systems with legacy IPs default to RPR mode. Up to two legacy IPs can be supported by RPR+ if the service single-slot-reload-enable command is configured.
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gt_rpr2.html#wp1057189
Legacy IPs default to RPR. To allow RPR+ for VIPs when up to two legacy IPs exist in the router, you must configure the service single-slot-reload-enable command. If you do not enable the service single-slot-reload-enable command or if you have more than two legacy IPs, all the line cards are reloaded.
Hope to help
Giuseppe
