If you do not enter this command or do not specify a keyword, the SSH
server selects the latest SSH version supported by the SSH client. For
example, if the SSH client supports SSHv1 and SSHv2, the SSH server
selects SSHv2.
Specify the timeout value in seconds; the default is 120 seconds. The
range is 0 to 120 seconds. This parameter applies to the SSH negotiation
phase. After the connection is established, the ML-Series card uses the
default timeout values of the CLI-based sessions.
By default, up to five simultaneous, encrypted SSH connections for
multiple CLI-based sessions over the network are available (session 0 to
session 4). After the execution shell starts, the CLI-based session timeout
value returns to the default of 10 minutes.
Specify the number of times that a client can reauthenticate to the server.
The default is 3; the range is 0 to 5.
Return to privileged EXEC mode.
Show the version and configuration information for your SSH server.
Show the status of the SSH server connections on the ML-Series card.
