7206 High input Flushes, Output errors and High CPU
I am stumped. On all of our Serial Interfaces we are getting High rate of input Flushes and out put drops. What would cause the high rate of flushes. It seems to happen in spurts during our peak utilization periods severaltimes a day, over 1 million flushes a day on our ATM and 3 million flushes on our Ethernet. However our ATM bandwidth is not even 50% utilized during these peaks.Also our CPU useage seems to Idle at a rate of 13% and gets up to 20+%, with IP input only accounting for 2-5%. Is that a normal CPU Utilization. It seems high to me, If we unplug the ATM the CPU drops to about 1%

Re: 7206 High input Flushes, Output errors and High CPU
I am very interested in your post. I to had a very similar problem a while back. I did end up with a usable solution that hasn't bitten me yet but I was never happy with it. What I did was first switch the router card with a newer model that happened to have 12.2. (I was running 12.1 at the time) I also had multiple 4mb PVCs terminating on one single DS3 card so I installed 2 more DS3 cards and separated the incoming PVC evenly over the cards 3 cards.
My reasoning for these changes were 1 I was confused because I had plenty of CPU but it was acting like I had a lag. And 2 I had tried everything possible as far as buffer size and PVC size.
Hopefully someone else has had this issue and can give you a better solution.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
