CH A P T E R 1 Using the Command-Line Interface The switches are supported by Cisco IOS software. This chapter describes how to use the switch command-line interface (CLI) to configure software features. For a complete description of the commands that support these features, see Chapter 2, “Cisco Catalyst Blade Switch 3120 for HP Cisco IOS Commands.” For information on the boot loader commands, see Appendix A, “Cisco Catalyst Blade Switch 3120 for HP Boot Loader Commands.
Chapter 1 Using the Command-Line Interface CLI Command Modes CLI Command Modes This section describes the CLI command mode structure. Command modes support specific Cisco IOS commands. For example, the interface interface-id command only works when entered in global configuration mode.
Chapter 1 Using the Command-Line Interface CLI Command Modes Table 1-1 Command Modes Summary (continued) Command Mode Access Method Prompt Exit or Access Next Mode VLAN configuration From privileged EXEC mode, enter the vlan database command. Switch(vlan)# To exit to privileged EXEC mode, enter the exit command. Line configuration From global configuration mode, Switch(config-line)# specify a line by entering the line command. To exit to global configuration mode, enter the exit command.
Chapter 1 Using the Command-Line Interface CLI Command Modes Global Configuration Mode Global configuration commands apply to features that affect the device as a whole. Use the configure privileged EXEC command to enter global configuration mode. The default is to enter commands from the management console.
Chapter 1 Using the Command-Line Interface CLI Command Modes config-vlan Mode Use this mode to configure normal-range VLANs (VLAN IDs 1 to 1005) or, when VTP mode is transparent, to configure extended-range VLANs (VLAN IDs 1006 to 4094). When VTP mode is transparent, the VLAN and VTP configuration is saved in the running configuration file, and you can save it to the switch startup configuration file by using the copy running-config startup-config privileged EXEC command.
Chapter 1 Using the Command-Line Interface CLI Command Modes Line Configuration Mode Line configuration commands modify the operation of a terminal line. Line configuration commands always follow a line command, which defines a line number. Use these commands to change terminal parameter settings line-by-line or for a range of lines. Use the line vty line_number [ending_line_number] command to enter line configuration mode. The new prompt means line configuration mode.
