Configuration Commands
Configuration commands are privileged level commands used to modify switch
settings. These commands modify the running configuration only and are not saved
when the switch is rebooted. To store the running configuration in non-volatile
storage, use the copy running-config startup-config command.
The configuration commands are organized into different modes:
• Global Configuration - These commands modify the system level configuration,
and include commands such as hostname and snmp-server community.
• Access Control List Configuration - These commands are used for packet filtering.
• Interface Configuration - These commands modify the port configuration such as
speed-duplex and negotiation.
• Line Configuration - These commands modify the console port and Telnet
configuration, and include command such as parity and databits.
• VLAN Configuration - Includes the command to create VLAN groups.
To enter the Global Configuration mode, enter the command configure in Privileged
Exec mode. The system prompt will change to “Console(config)#” which gives you
access privilege to all Global Configuration commands.
To enter the other modes, at the configuration prompt type one of the following
commands. Use the exit or end command to return to the Privileged Exec mode.
