NOTE:
E1 configurations are supported on the IMA (E1) interface module and T1 configurations on the IMA (T1)
interface module.
Troubleshooting ATM E1/T1 interfaces
You can start troubleshooting an ATM interface by testing network connectivity using the ping command
or the extended ping command. In an extended ping command, specify some options in the IP header.
For more information about the ping command, see Network Management and Monitoring
Configuration Guide.
If the interface cannot be pinged, check whether:
• The interface is down.
• The AAL5 encapsulation type of the PVC is incorrect.
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:

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.
