R3303-HP HSR6800 Routers Interface Configuration Guide

Configuring an ATM OC-3c/STM-1 interface

Overview

This section covers only the physical configurations of the interface. For more information about how to

configure ATM (including PVCs), see Layer 2—WAN Configuration Guide.

Configuration procedure

To configure an ATM OC-3c/STM-1 interface:

Step Command Remarks

1. Enter system view.

system-view N/A

2. Enter ATM OC-3c/STM-1

interface view.

interface atm interface-number N/A

3. Set the clock mode.

clock { master | slave }

Optional.

The default setting is slave.

4. Set the framing format.

frame-format { sdh | sonet }

Optional.

The default setting is SDH STM-1.

5. Enable scrambling.

scramble

Optional.

Scrambling is enabled by default.

6. Configure the overhead bytes.

flag c2 flag-value

flag { j0 | j1 } { sdh | sonet }

flag-value

Optional.

The default is hexadecimal 13 for

C2.

By default, SDH framing applies. In

SDH framing, the defaults are null

for both J0 and J1.

Support for keywords sdh and

sonet varies with device models.

7. Set the loopback mode.

loopback { cell | local | remote }

Optional.

Loopback is disabled by default.

8. Set the intended bandwidth

for the ATM OC-3c/STM-1

interface.

bandwidth bandwidth-value Optional.
