We have a VPN accelerator module in a CAT 6500/Sup2. A tunnel is configured on this switch and use this module to accelerate IPsec encryption. Now, the CPU usage of this switch is a bit of high, once in a while. I suspect it is something to do with the encryption. I am just wondering, is there any way that I know it?
for instance, is there any tunnel related traffic or processing is directed to RP, in stead of staying in the accelerate module? how efficent the module is beng used? is the module overload?
