High CPU on Cisco2500 with Encrypt 512k.

By morshidi.m.saufi ·
My Cisco 2500 router(IOS 11.2) suffers high CPU utilisation (Encrytion process can shoot up to 99%)when using a 512K leased line.How do I configure the router so that it only has a bandwith of 128K which is the max the 2500 router can take when running Crypto?This means to say that my 384K is not use until it is replaced with a more powerful router.

You cannot do that on the router. It will use whatever bandwidth is there.

You MAY be able to acconplish what you want, however, by TELLING the Cisco that it's bandwidth on the leased line is only 128.

At the Interface prompt in config mode:
bandwidth 128

Bandwidth 128k is for IP routing only.Any ways to reduce encryption process since the the serial and ethernet interfaces utilization is very low.What makes the encryption process to occupy the cpu?
