Enhancements in Release F.04.08
Configuring Secure Shell (SSH)
To Generate or Erase the Switch’s Public/Private RSA Host Key Pair.
Because the host key
pair is stored in flash instead of the running-config file, it is not necessary to use
write memory to save
the key pair. Erasing the key pair automatically disables SSH.
Syntax:
crypto key generate [rsa]
Generates a public/private key pair for
the switch. If a switch key pair already exists, replaces
it with a new key pair. (See the Note, above.)

crypto key zeroize [rsa]

"Zeroizing" the switch’s key automatically disables SSH (sets
IP SSH to No). Thus, if you zeroize the
key and then generate a new key, you must also re-enable SSH with the
ip ssh command before the
switch can resume SSH operation.
