Saving Configuration Changes - Cisco RJ-45-to-AUX Brochure

Switch(config−if)#interface e0.1
Switch(config−subif)#
Tip You can abbreviate any command as much as you want, as long as it remains unique (no other command
exists that matches your abbreviation). For instance, the command interface e0.1 can be abbreviated as
int e0.1.
To exit to Global Configuration mode, use the exit command or press Ctrl+Z.
Tip Entering a question mark (?) in any mode will display the list of commands available for that particular
mode. Typing any command followed by a question mark—such as clock ?—will list the arguments
associated with that command. You can also type the first few letters of a command immediately followed
by a question mark. This will list all the commands starting with the entered letters.

Saving Configuration Changes

When you're saving the configuration, the Set/Clear IOS−based switches are identical to the IOS−based CLI.
The configuration modes allow you to make changes to the running configuration. In order to save these
changes, you must save the configuration.
There are two types of configuration files: Startup configuration files are used during system startup to
configure the software, and running configuration files contain the current configuration of the software. The
two configuration files do not always agree.
To make a change to the running configuration file:
1. Issue the command configure terminal.
2. Make any necessary changes.
3. When you are done, copy the running configuration to the startup configuration.
In the following example, the hostname is being changed and then saved to the start−up configuration:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# hostname BBSwitch
BBSwitch (config) end
BBSwitch# copy running−config startup−config
