encapsulation
Syntax encapsulation atm-encap-type
Context config>service>epipe>sap>atm
config>service>ipipe>sap>atm
Description
This command specifies the data encapsulation for an ATM PVCC delimited SAP. The definition
references RFC 2684, Multiprotocol Encapsulation over ATM AAL5, and to the ATM Forum LAN
Emulation specification.
Ingress traffic that does not match the configured encapsulation will be dropped.
Default
The encapsulation is driven by the services for which the SAP is configured.
For IES and VPRN service SAPs, the default is aal5snap-routed.
Parameters
atm-encap-type — Specify the encapsulation type.

Description
This command assigns an ATM traffic descriptor profile to a given context (for example, a SAP).
When configured under the ingress context, the specified traffic descriptor profile defines the traffic
contract in the forward direction.
When configured under the egress context, the specified traffic descriptor profile defines the traffic
contract in the backward direction.
The no form of the command reverts the traffic descriptor to the default traffic descriptor profile.
Default
The default traffic descriptor (trafficDescProfileId. = 1) is associated with newly created PVCC-
delimited SAPs.
Parameters
traffic-desc-profile-id — Specify a defined traffic descriptor profile (see the QoS atm-td-profile
7750 SR OS Services Guide
