show ssl certificates 

Description

Display information about the Secure Sockets Layer (SSL) certificates installed on the switch. When you configure PEAP as the authentication protocol for MAC RADIUS authentication, you must load the server-side Secure Sockets Layer (SSL) certificate on the switch. PEAP requires an SSL certificate to create a secure TLS tunnel to protect user authentication, and uses server-side public key certificates to authenticate the server. It then creates an encrypted TLS tunnel between the client and the authentication server. The key for this encryption are transported using the server's public key. The ensuing exchange of authentication information inside the tunnel to authenticate the client is then encrypted and user credentials are safe from eavesdropping.

Options

`detail`	Display information about SSL certificates for the specified level of output.
