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 [...]
You can use the VLAN configuration commands to create or modify VLAN parameters for VLAN IDs 1 to 1005. Enter the vlan database privileged EXEC command to access VLAN configuration mode: Switch# vlan database Switch(vlan)# The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, [...]
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 [...]
Interface configuration commands modify the operation of the interface. Interface configuration commands always follow a global configuration command, which defines the interface type.

Current configuration: ! version 11.2 ! hostname [...]
Once an EXEC session is established, commands within Cisco IOS are hierarchically structured. In order to successfully configure the router, it is important to understand this hierarchy. To illustrate this hierarchy, Figure 1 provides a simple high-level schematic diagram of some IOS commands.
