Table 1 Support for ATM applications
ATM application aal5snap aal5mux aal5nlpid
IPoA Supported Supported Supported
IPoEoA Supported Supported Not supported
PPPoA Supported Supported Not supported
PPPoEoA Supported Supported Not supported
High MBS settings might result in the failure of the service vbr-rt and vbr-nrt commands because of
hardware limitations. To avoid the situation, set MBS to a smaller value.
With aal5snap adopted, two or more protocols are supported. But for aal5nlpid, you cannot enable
InARP on a PVC for an IPoA application.
Configuring VE interfaces
To configure a PVC to carry PPPoEoA or IPoEoA, you must first specify a VE interface for the channel. If
not, the permanent virtual channel cannot be created.

Command Remarks
1. Enter system view.
system-view N/A
2. Create a Layer 3 VE
interface and enter
its view.
interface virtual-ethernet
interface-number
If a specified Layer 3 VE interface does not
exist, this command first creates one and then
enters its view.
3. Set the interface
description.
description text
Optional.
By default, the description for a VE interface
is interface name Interface, for example,
Virtual-Ethernet2/0/0 Interface.
4. Configure the MAC
address for the
interface.
mac-address mac-address Optional.
5. Set the intended
bandwidth for the
interface.
bandwidth bandwidth-value Optional.
6. Shut down the
interface.
shutdown
Optional.
Up by default.
Configuring IPoA
When you configure IPoA, follow these guidelines:
• If you execute the map ip command with the broadcast keyword, which specifies pseudo broadcast,
any broadcast packets received by the port on which the PVC is created will be duplicated to the
PVC. Therefore, to propagate broadcast or multicast packets on an ATM PVC with a broadcast or
multicast protocol enabled, specify the broadcast keyword.
