Configuring The Atm Aal5 Encapsulation Type - HP MSR Router Series Wan Access Configuration Manual

Step
1. Enter system view.
2. Enter ATM interface view
or ATM subinterface
view.
3. Create a PVC-group and
enter PVC-group view.
4. Create a PVC and enter
PVC view.
5. Configure priority of IP
packets carried by the
PVC.
6. Bring up the PVC.

Configuring the ATM AAL5 encapsulation type

ATM AAL5 encapsulation includes the following types:
aal5snap—Logical Link Control (LLC)/Subnet Access Protocol (SNAP) encapsulation.
•
aal5mux—MUX multiplexing encapsulation.
•
aal5nlpid—RFC 1490 encapsulation.
•
Different encapsulations use different formats and support different mappings.
aal5snap—Supports IPoA, IPoEoA, PPPoA, and PPPoEoA mappings.
•
• aal5mux—Supports IPoA, IPoEoA, PPPoA, and PPPoEoA mappings, but can only support one
protocol at a time.
aal5nlpid—Supports only IPoA mappings.
•
Follow these guidelines when you configure ATM AAL5 encapsulation types:
Devices on the two ends must be configured with the same ATM AAL5 encapsulation types.
•
Only aal5snap supports InARP. You cannot configure InARP when aal5mux or aal5nlpid is used.
•
Although a PVC or PVC-group can carry multiple protocols, a specific encapsulation type might not
•
support some of the applications (such as IPoA, IPoEoA, PPPoA, and PPPoEoA). In such cases, the
system displays error prompts.
When you change the encapsulation type for a PVC or PVC-group, and the mappings that you have
•
configured conflict with the new encapsulation type, the PVC or PVC-group deletes the
configurations of all conflicting mappings.
To configure the ATM AAL5 encapsulation type:
Step
1. Enter system view.
2. Enter ATM interface view
or ATM subinterface
view.
Command
system-view
interface atm { interface-number |
interface-number.subnumber }
pvc-group group-number
pvc { pvc-name [ vpi/vci ] | vpi/vci }
precedence { min [ to max ] | default }
undo shutdown
Command
system-view
interface atm { interface-number |
interface-number.subnumber }
