Configuring Vp Policing; Configuring Applications Carried By Atm; Configuring Ipoa - H3C SR6600 Configuration Manual

Error messages appear when configurations performed to a PVC are invalid.

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
satisfied, 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.
Follow these steps to set the parameters of VP policing:
To do...
Enter system view
Enter ATM interface view
Set the parameters of VP policing

Configuring Applications Carried by ATM

Although ATM can carry multiple protocols, a specific encapsulation type may not support ATM
applications (such as IPoA, IPoEoA, PPPoA, and PPPoEoA), as listed in the following table.

IPoEoA

PPPoEoA
High MBS settings may 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 IPoA

Follow these steps to configure IPoA:
To do...
Enter system view
Enter ATM interface view
Create a PVC, and enter PVC view
Use the command...
system-view
interface atm interface-number
pvp limit vpi output-scr
aal5snap
