encapsulation
Use encapsulation to specify an ATM AAL5 encapsulation type for a PVC.
Use undo encapsulation to restore the default.
Syntax
encapsulation aal5-encap
undo encapsulation
Default
Aal5snap encapsulation is used.
Views
PVC view, ATM class view
Default command level
2: System level
Parameters
aal5-encap: Specifies an AAL5 encapsulation type. The following are available values:
• aal5mux—MUX encapsulation
• aal5nlpid—RFC1490 encapsulation
• aal5snap—LLC/SNAP encapsulation
Usage guidelines
Among aal5snap, aal5mux and aal5nlpid, only aal5snap encapsulation supports InARP.
If InARP is enabled, you must disable it before changing AAL5 encapsulation to aal5mux or aal5nlpid.
An ATM PVC can carry multiple protocols simultaneously, but certain types of encapsulation might not
support some applications (one or more of IPoA, IPoEoA, PPPoA, and PPPoEoA). When such cases occur,
the system gives a prompt.
Examples
# Set the AAL5 encapsulation of PVC 1/32 on interface ATM 1/0/1 to aal5nlpid.
<Sysname>system-view
[Sysname] interface atm 1/0/1

interface atm
Use interface atm to create an ATM subinterface or enter an ATM subinterface view.
Use undo interface atm to delete ATM subinterface.
Syntax
