    Syntax

    encapsulation encapsulationType

    no encapsulation

    Release Information

    Command introduced in JunosE Release 7.1.0.
    ATM VC Class Configuration mode added in JunosE Release 7.3.0.

    Description

    In ATM VC Configuration mode, configures the encapsulation method on an ATM PVC. The encapsulation method represents the format of the data units that traverse the PVC. The encapsulation command is valid only for data PVCs; you cannot use this command for control (ILMI or signaling) PVCs. The no version restores the default encapsulation method, aal5snap.

    In ATM VC Class Configuration mode, configures the encapsulation method as part of a VC class definition that you assign to an ATM data PVC. The no version restores the default encapsulation method, aal5snap, in the VC class.

    Options

    • encapsulationType—One of the following encapsulation methods for data PVCs:
      • aal0—Causes the router to receive raw ATM cells on this PVC and forward the cells without performing AAL5 packet reassembly
      • aal5all—Configures ATM over MPLS passthrough connections; the router passes through all ATM AAL5 traffic without interpreting it
      • aal5autoconfig—Enables autodetection of the 1483 encapsulation (LLC/SNAP or VC multiplexed)
      • aal5mux ip—Configures a VC-based multiplexed circuit used for IP only
      • aal5snap—Configures an LLC encapsulated circuit; an LLC/SNAP header precedes the protocol datagram

    Mode

    ATM VC Configuration, ATM VC Class Configuration
