My border router which is in the LAN, of late has started giving erratic ping(1000ms) and timeout yet it is just in the LAN after a reset it come to normal (ping response becomes an average 5ms)but when the traffic goes thro it ping response degrades.We use static ip routes, AL and NATing(sorry but am not allow to post the configs) any ideas why it is so. i have checked loop back configs but none. Any help will be appreciated
Thanks medan for the lead for sure when the ping become erratic the cpu utilization is around 98-100% which it has never attained before.The processes which takes most of the CPU time is IP Input, and TurboACL.
If this is happening consistently, I would configure netflow on the router to see if you can determine what traffic is going through the router. You can then block that traffic to see if it helps your throughput.
Thanks John but i have all kinds of traffic( from clients) flowing thro the router i just need to pin which IP, AL, or config is causing the mess.From the records the issue happens like thrice in a day each time i do a reset things are normal.
Thanks i will try netflow tho i have never configured it, give me time i try my hands on a demo router then on the BR because its critical each reset causes an uproar. The issue happens depending on traffic flow. The higher the traffic the faster it times out. Will get back to you once am done.
