Parameter
aal5-encap: AAL5 encapsulation type, its possible values are as follows:
aal5snap: LLC/SNAP (Logical Link Control / Subnet Access Protocol)
encapsulation type
aal5mux: MUX encapsulation type
aal5nlpid: RFC1490 encapsulation type
Description
Using the encapsulation command, you can specify ATM AAL5 encapsulation type
for PVC. Using the undo encapsulation command, you can restore the default
encapsulation.
By default, aal5snap encapsulation is adopted.
Only aal5snap encapsulation supports InARP protocol. InARP is not supported
when aal5mux and aal5nlpid encapsulations are adopted.
To change the encapsulation type for PVC to aal5mux or aal5nlpid, InARP must be
deleted first.
In addition, some types of encapsulations may not support some applications
method (one or more of IPoA, IPoEoA, PPPoA and PPPoEoA). When such cases
appear, the system will give a prompt.
Example
The two examples can both specify AAL5 encapsulation type of PVC as aal5snap.
Display how to specify AAL5 encapsulation type of PVC 1/32 as aal5snap.
[3Com-atm-pvc-Atm1/0/0-1/32] encapsulation aal5snap
Display how to specify AAL5 encapsulation type of PVC 1/33 as aal5snap.
