Configuring the Data Link Layer Protocol for E1, T1, and Serial Interfaces
Quick Start
5. For CHAP, enter a username only if it is different from the router’s
hostname:
Syntax: ppp chap hostname <username>
For example, you might enter:
ProCurve(config-ppp 1)# ppp chap hostname ProCurveA
Frame Relay
Before you begin to configure the Frame Relay interface, you should know
the settings that you must enter for the following:
■ Frame Relay signaling role:
• user, or data terminal equipment (DTE)
• network, or data communications equipment (DCE)
• both, or network-to-network interfaces (NNI)
■ Frame Relay signaling type, which is referred to as the link management
interface (LMI)
■ data link connection identifier (DLCI)
■ your negotiated committed information rate (CIR), which is configured
as your B
c
■ your negotiated excess information rate (EIR), which is configured as
your B
e
.
Your public carrier should provide you with this information.
Note With few exceptions, you will configure the signaling role as DTE. However,
the other options are available if you need to change the setting for any reason.
For example, you may want the router to act as a DCE in a test WAN
environment.
To configure Frame Relay for an E1, T1, or serial interface, complete these
steps:
1. From the global configuration mode context, create a Frame Relay inter-
face.
Syntax: interface <interface> <number>
ProCurve(config)# interface frame-relay 1
