Problem with adding switches to CNA

[Muhammad Bayat]

Hi

I configured my switches with line vty password and enable secret and I enabled services password-encryption on my switches. I try to add switches to CNA with enable secret without any username but I couldn't. CNA dosn't accept my enable secret. What is my problem and with what credentials I can add switches to CNA?

Have you enabled http(s) server? That's required.
