Saving Configuration Changes; Configuring Isdn - HP J3138A Installation Manual

Saving Configuration Changes

Any time you make changes to the router configuration, you must save the
changes to memory because if you do not they will be lost if there is a system
reload or power outage. There are two types of configuration files: the running
(current operating) configuration and the startup configuration. The running
configuration is stored in RAM; the startup configuration is stored in NVRAM.
To display the current running configuration, enter the show running-config
command. Enter the copy running-config startup-config command to save
the current running configuration to the startup configuration file in NVRAM.
To display the startup configuration, enter the show startup-config
command. Enter the copy startup-config running-config command to write
the startup configuration to the running configuration:
To erase both configuration files (and start over), enter the write erase and
reload commands:
C A U T I O N
This command sequence will erase the entire router configuration in RAM and
NVRAM and reload the router.

Configuring ISDN

This section describes a recommended ISDN configuration for one or two B
channels. In the examples that follow, the BRI port is configured for IP routing,
Challenge Handshake Authentication Protocol (CHAP), and Point-to-Point
Protocol (PPP) encapsulation.
For your reference, an example configuration follows in the next section,
"Example ISDN Configuration". You may want to refer to Example ISDN
