User Guidelines
The key string is the public key of the specified type (RSA or DSA) generated
by the administrator. The administrator will need access to both the public
and private key on the host to log in without authenticating via password.
DSA is considered less secure than RSA. Use of RSA is recommended.
Use the key-string row command to enter the key-string one row at a time.
The row may be enclosed in quotes. This command may be used to enter the
key one line at a time should the key-string be greater than 234 characters in
length.
Use the key-string command without the row parameter to enter the entire
key at once if the key-string does not exceed 234 characters.
The switch accepts keys up to 2048 bits in length.
Command History
Modified in version 6.5 firmware.
