Re: Un Known configuration at my switch

Kranthi

The crypto certificate is included in the config by the operating system code. It is to support machine authentication. Traditionally we have done most authentication with pre-shared keys and passwords. Authenticating with certificates is another alternative for machine authentication. The crypto certificate is here to support that if your implementation chooses to use it.

It will not hurt anything to leave it in the config. And if you are not planning to do certificate based authentication it will not hurt anything if you remove it.

Re: Un Known configuration at my switch

I believe a 3750, if you have a crypto image, will create its own certificate to support SSH access to the switch.
