3660 Encryption AIM

Hello, I have suspiction (low performance), that my encryption aim is not running. If i type "show crypto engine accelerator brief" the output contains:

"

crypto engine name: unknown

crypto engine type: ISA/ISM

...

crypto engine name: unknown

crypto engine type: software

...

crypto engine state: installed

crypto engine in slot: N/A

"

I am concerned about that "software" type.

When I try crypto engine accelerator command, the output is, that encryption is already enabled. Software is c3660-ik2o3s-mz.121-3a.XI5(have to be OK). Is any way to definitely recognize if the AIM is running? Thanks for any ideas. Steve

Hi Steve,

you can type " sh cry eng acceler stat" to see if your encryption card is processing the packets ( i.e, encrypting or decrypting the packets )

Hope that helps

Re: 3660 Encryption AIM

Thanx, I know this command, but i'm not sure about the output. From the first part (Encryption AIM in aim slot:) i should derive that it is ok, but from the part (EncryptionAIM0/13:) i have derived, that the AIM is not running. What do You think?

sh crypto eng accel stat

Re: 3660 Encryption AIM

Can you please run:

SV3-9#sh cry engine config

crypto engine name: Virtual Private Network (VPN) Module

crypto engine type: hardware

if it is in software you will see the following:

SV3-9#sh cry engine config

crypto engine name: Virtual Private Network (VPN) Module

crypto engine type: software

Let me know if you have any problems running this command.

Re: 3660 Encryption AIM

Hello Catherine,

I have tried this before:

sh crypto engine config

crypto engine name: unknown

crypto engine type: ISA/ISM

From this output I suppose, that it stands for hardware encryption.

However, other diagnostic commands outputs are not clear enough. I give it up and believe in hardware encryption.

Thanks a lot.

Steve
