Step Command Remarks
8. Enter ATM interface view or
PVC view
• Enter ATM interface view:
interface atm
{ interface-number |
interface-number.subnumbe
r }
• Enter PVC view:
pvc { pvc-name [ vpi/vci ] |
vpi/vci }
N/A
9. Enable the ATM class on the
interface or PVC
atm-class
atm-class-name N/A
Configuring VP policing
VP policing is used to set the sustainable rate of a virtual path identifier (VPI). When applying VP
policing, the parameters of PVC are still valid. Only when the parameters of PVC and VP policing are
met, will the packets be transmitted or received. In calculating the traffic, the LLC/SNAP, MUX and
NLPID headers are included, but the ATM cell header is not included.
To set the parameters of VP policing:
Step Command
1. Enter system view.

2. Enter ATM interface view.

3. Set the parameters of VP policing.

Configuring applications carried by ATM
In Table 3, although ATM can carry multiple protocols, a specific encapsulation type might not
support ATM applications (such as IPoA, IPoEoA, PPPoA, and PPPoEoA).

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 Layer 3 VE interfaces
To configure a PVC to carry PPPoEoA, IPoEoA, and EoA, you must first specify a VE interface for
the channel. If not, the permanent virtual channel cannot be created.
