Dear All
I have 7200 router, it was runing 124-4.XD3 IOS, the CPU was working normal avarage around 15%, its use for L2TP users, it was have avarage 2000 concurrent L2TP connection, there was no CPU consuming.
Then for business plan we change the IOS to 12.2(33)SR and configured Broadband aggregation, after that the CPU become higher day after day even the PPPoE and L2TP session not more than 900 concurrent. the CPU reach 60%, even in non-peak hours it reach 50%

It is hard to identify root cause by the explanation given. It could be a memory leak, route flapping or process switching issue. I believe you need to open a TAC case to troubleshoot this further.

Hi There,
Just want to share a tip on ow to filter your CPU utilisation on your Cisco router. I find alias commands handy and use them all the time. From the config mode, you can type as below.
R(config)#alias exec cpu sho process cpu sorted | exc 0.00%__0.00%__0.00%
This will create an alias called cpu, from priviledge mode, you can then type cpu and it will filter all process' that are not consuming the CPU, this is done with the help of exc [exclude]. This excludes all process' with 0% utilisation.
Below is my example on one of my routers.
Thanks,
Faraimd
