Purpose
Configure the SSH control parameters:
Specify the time-out 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 switch uses
the default time-out 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
time-out value returns to the default of 10 minutes.
Specify the number of times that a client can re-authenticate to the
server. The default is 3; the range is 0 to 5.
Repeat this step when configuring both parameters.
(Optional) Configure the virtual terminal line settings.
Enter line configuration mode to configure the virtual terminal line
settings. For line_number and ending_line_number, specify a pair of
lines. The range is 0 to 15.
Specify that the switch prevent non-SSH Telnet connections. This
limits the router to only SSH connections.
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 switch.
(Optional) Save your entries in the configuration file.
