Self-signed certificates
Administrators may prefer to not set up a Certificate Authority and implement a certificate trust model in the network, but still want to use
the privacy features provided by the Transport Layer Security (TLS) protocol. In this case, self-signed certificates can be used.
A self-signed certificate is not signed by a CA. The switch presents itself as a trusted device in its certificate. Connecting clients may
prompt their users to trust the certificate — for example, when a web browser warns that a site is unsafe — or to reject the certificate,
depending on the configuration. A self-signed certificate does not provide protection against man-in-the-middle attacks.
To generate and install a self-signed certificate:
1. Create a self-signed certificate and key in a local directory or USB flash drive.
2. Install the self-signed certificate.
Generate a self-signed certificate
• Create a self-signed certificate in EXEC mode. Store the device.key file in a secure, persistent location, such as NVRAM.
