Configuring an ATM subinterface

An ATM subinterface supports the same network layer functions as an ATM interface. The network layers
of different ATM subinterfaces are independent of each other. You can configure different Layer 3
services for ATM subinterfaces, such as IP services and MPLS services. To enable an ATM interface to
support multiple Layer 3 services, create multiple subinterfaces for the interface.
The rate of an ATM subinterface depends on the rates of the PVCs or PVC-groups configured on the
subinterfaces. For more information, see Layer 2—WAN Configuration Guide.
To configure an ATM subinterface:
Step
1. Enter system view.
2. Create an ATM
subinterface and enter its
view.
3. Configure the subinterface
description.
4. Configure the expected
bandwidth for the
subinterface.
5. Configure an MTU value
for the subinterface.
6. Restore the default of the
subinterface.
7. Bring up the subinterface.

Configuring an EFM interface

Ethernet First Mile (EFM) interfaces receive and transmit Ethernet frames over ATM physical links and use
the Ethernet protocol suite. They can transmit Ethernet frames over legacy DSL lines and achieve
all-Ethernet access. By implementing stable, high-speed Ethernet packet transmission over telephone lines,
EFM extends the transmission distance of Ethernet from 100 meters to 1500 meters. With EFM interfaces,
the Ethernet technologies can be deployed on the access networks of telecom users, which improves
network performance and lowers device and operation costs.
The physical link type of EFM interfaces is EFM SHDSL_8WIRE_BIS (eight-wire G.SHDSL.BIS).

Remarks
N/A
By default, the interface is up.
HP recommends that you shut down
the unused G.SHDSL interfaces to
save system resources.
Remarks
N/A
By default, no ATM subinterface is
created.
By default, the description is
interface-name Interface.
By default, the expected bandwidth
(in kbps) is the interface baud rate
divided by 1,000.
By default, the MTU value for the
subinterface is 1,500 bytes.
N/A
By default, the subinterface is up.
