You can use scripts to expedite and automate Administration Console tasks. Any command you enter in the Administration Console can become part of a script. You can even script your entire system setup so that you can repeat the exact setup on another Switch 2200.

You create scripts in an ASCII-based line editor, such as EMACS or vi. To run them from the Administration Console, you must access the directory where your scripts are stored. When writing scripts, you can use the number symbol (#) to identify comments in the script.

To run a script:

1From the top level of the Administration Console, enter:

script

You are prompted for information about where you have stored the script you want to run: host IP address, ﬁle path name, user name, and password. Press [Return] at any prompt to use the value in brackets.

2Enter the host IP address of the system where the script resides.

3Enter the path name.

4Enter your user name.

5Enter your password.

6Enter the name of the script.
