Exiting a Lower Level Environment

The multiple-level nature of the software places you in secondary, tertiary, and even lower level environments as you con®gure or operate the 2210. To return to the

next higher level, enter the exit command. To get to the secondary level, continue entering exit until you receive the secondary level prompt (either Config> or +).

For example, to exit the IP protocol con®guration process:

IP config> exit

Config>

If you need to get to the primary level (OPCON), enter the intercept character (Ctrl

P by default).

Getting Back to OPCON

To get back to the OPCON prompt (*), press Ctrl-P. You must always return to OPCON before you can communicate with another process. For example, if you are connected to the GWCON process and you want to connect to the CONFIG process, you must press Ctrl-Pto return to OPCON ®rst. TheCtrl-Pkey combination is the default intercept character.

If you use the intercept character from a third-level or lower level process to return to the * prompt, the next time you use the talk command, you will reenter the third level process. This link goes away when the router is re-initialized.

Some Con®guration Suggestions

Con®guring a 2210 is different depending on whether you are con®guring for the ®rst time, creating a con®guration based on an existing con®guration, or just updating a con®guration. Use the following sections as a guide to the best procedure to use, depending on your needs.

Creating a First Con®guration

This procedure assumes that you have no other 2210 that contains a con®guration similar to the one for the 2210 you are con®guring. The procedure also assumes that you have just taken the 2210 out of the box. Although this procedure speci®es an order, you can perform the actual con®guration (after step 3) in any order.

To con®gure a IBM 2210 for the ®rst time:

1.Examine the 2210 you are con®guring to determine which interfaces you need to con®gure. Note these for later use.

2.Connect to the 2210 as described in ªAccessing the Software Using Local and Remote Consolesº on page 3.

3.Initially con®gure a port on the 2210 and at least an internal IP address for the device using Quick Con®g as described in ªQuick Con®gurationº on page 42 or ªAppendix A. Quick Con®guration Referenceº on page 651. Con®gure the minimum needed to allow you to Telnet into the device.
