aal5-encap: AAL5 encapsulation type; its possible values are as follows:
aal5mux: MUX encapsulation type

PVC.
Use the
undo encapsulation
By default, aal5snap encapsulation is adopted.
Note that:
Among aal5snap, aal5mux and aal5nlpid, only aal5snap encapsulation
■
supports InARP.
If InARP is enabled, you need to disable it before change AAL5 encapsulation
■
to aal5mux or aal5nlpid.
An ATM PVC can carry multiple protocols simultaneously, but certain types of
■
encapsulations may not support some applications (one or more of IPoA,
IPoEoA, PPPoA and PPPoEoA). When such cases occur, the system gives a
prompt.
