Cisco 877 High CPU

[abidu]

Hello all,

Whenever the clients behind the router and making traffic (downloading at max speed) the router's CPU goes to 99% all the time, note that behind the router is just one client. So far I ruled out the modem firmware and the IOS, also the IPS provides a bandwidth of 12mbps and due to the router's CPU issue more that 9mbps is not achieved.

IOS: c870-advipservicesk9-mz.150-1.M
Modem FW: 4.0


Any suggestions would be greatly appreciated.
Thanks

Hey Abidu,

Your packets are likely being 'process switched' instead of switched through fast switching or CEF. You definitely need to enable CEF with the following command:

ip cef

If that doesn't work or help to alleviate, post output from the following:

show proc cpu sorted
show cef not
show int switching

You can read more about CEF here if you are unfamiliar:

http://www.cisco.com/en/US/docs/ios/12_1/switch/configuration/guide/xcdcef.html

Good luck.

Your suggestion helped with the CPU but the download speed remains the same.

what does the output of sh dsl int atm0 show??

[imbadatthis]

I thought ip virtual-reassembly caused performance issues?

cisco's site says it does:

Restrictions for Virtual Fragmentation Reassembly

Performance Impact

VFR will cause a performance impact on the basis of functions such as packet copying, fragment validation, and fragment reorder. This performance impact will vary depending on the number of concurrent IP datagram that are being reassembled.

http://cisco.biz/en/US/docs/ios/12_3t/12_3t8/feature/guide/gt_vfrag.html

We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.

Things are much better now with ip cef enabled and Virtual Fragmentation Reassembly disables on all interfaces.

CPU is around ~50% when the traffic is at maximum.
The download speed has improver close to 12mbps.


Thank you for all the help and ideas.

Good to hear. I would also recommend removing the 'ip flow ingress' on the ATM interfaces if you do not use NetFlow. That will eat up process cycles, too.
