Configuring Secure Shell (SSH)
Configuring the Switch for SSH Operation
Option B: Configuring the Switch for Client Public-Key SSH
Authentication.
If configured with this option, the switch uses its public
key to authenticate itself to a client, but the client must also provide a client
public-key for the switch to authenticate. This option requires the additional
step of copying a client public-key file from a TFTP or SFTP server into the
switch. This means that before you can use this option, you must:
1. Create a key pair on an SSH client.
2. Copy the client’s public key into a public-key file (which can contain up
to ten client public-keys).
3. Copy the public-key file into a TFTP or SFTP server accessible to the
switch and download the file to the switch.
(For more on these topics, refer to “Further Information on SSH Client Public-
Key Authentication” on page 8-25.)
With steps 1 - 3, above, completed and SSH properly configured on the switch,
if an SSH client contacts the switch, login authentication automatically occurs
first, using the switch and client public-keys. After the client gains login
access, the switch controls client access to the manager level by requiring the
passwords configured earlier by the
aaa authentication ssh enable
command.
Syntax: copy tftp pub-key-file < ip-address > < filename >
Copies a public key file into the switch.
aaa authentication ssh login public-key
Configures the switch to authenticate a client public-key at
the login level with an optional secondary password method
(default:
none
).
