Chapter 6 Configuring Switch-Based Authentication Configuring the Switch for Secure Shell Configuring the SSH Server Beginning in privileged EXEC mode, follow these steps to configure the SSH server: Step 1 Step 2 Command configure terminal ip ssh version [1 | 2] Step 3 ip ssh {timeout seconds | authentication-retries number} Step 4 Step 5 Step 6 end show ip ssh or show ssh copy running-config startup-config Purpose Enter global configuration mode. (Optional) Configure the switch to run SSH Version 1 or SSH Version 2. • 1-Configure the switch to run SSH Version 1. • 2-Configure the switch to run SSH Version 2. 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. 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. 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. 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 6-3: Table 6-3 Commands for Displaying the SSH Server Configuration and Status Command show ip ssh show ssh Purpose Shows the version and configuration information for the SSH server. Shows the status of the SSH server. OL-8915-01 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide 6-41
