Using client public-key authentication

Procedure
  1. Generate a public/private key pair for each client you want to have SSH access to the switch. This can be a separate key for each client or the same key copied to several clients.
  2. Copy the public key for each client into a client public-key text file.
  3. Use copy tftp to copy the client public-key file into the switch. Note that the switch can hold 100 keys. The new key is appended to the client public-key file
  4. Use the aaa authentication ssh command to enable client public-key authentication.
