Chapter 5 Configuring Switch-Based Authentication
Configuring the Switch for Secure Shell
To return to the default SSH control parameters, use the no ip ssh {timeout | authentication-retries}
global configuration command.
Displaying the SSH Configuration and Status
To display the SSH server configuration and status, use one or more of the privileged EXEC commands
in Table 5-2:
For more information about these commands, see the “Secure Shell Commands” section in the “Other
Security Features” chapter of the Cisco IOS Security Command Reference, Cisco IOS Release 12.2, at
this URL:

srfssh.htm.
Step 3
ip ssh {timeout seconds |
authentication-retries number}
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.
Step 4
end Return to privileged EXEC mode.
Step 5
show ip ssh
or
show ssh
Display the version and configuration information for your SSH server.
Display the status of the SSH server connections on the switch.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
