    Configuring a Base Profile to Apply Encapsulation, Traffic-Shaping and OAM Parameters to a Bulk Range of PVCs Configured on an ATM AAL5 Interface

    You can use the atm pvc command to apply encapsulation, traffic-shaping, and OAM parameters to the range of ATM PVCs configured on an ATM AAL5 interface for use by a dynamic ATM 1483 subinterface created with a base profile.

    You must specify one of the following encapsulation types:

    • aal5autoconfig—Enables autodetection of the 1483 encapsulation (LLC/SNAP or VC multiplexed)
    • aal5snap—Specifies a logical link control (LLC) encapsulated circuit; the LLC/Subnetwork Access Protocol (LLC/SNAP) header precedes the protocol datagram
    • aal5mux ip—Specifies a VC-based multiplexed circuit used for IP only

    You can optionally set the peak, average, and burst sizes. To use VBR-RT or VBR-NRT as the service type, you must specify each of these options.

    The default service type is UBR. To set a different service type, specify one of the following keywords:

    • rt—Selects VBR-RT as the service type; you can select rt only if you set the peak, average, and burst parameters
    • cbr—Selects CBR as the service type; you must set the CBR rate in Kbps

    You can optionally include the oam keyword and a number of seconds in the range 1–600 to enable generation of OAM F5 loopback cells on this circuit. This option enables VC integrity features that affect the operational state of the ATM PVC.

    To apply encapsulation, traffic-shaping, and OAM parameters to the range of ATM PVCs configured on an ATM AAL5 interface for use by a dynamic ATM 1483 subinterface created with a base profile:

    • Issue the atm pvc command in Profile Configuration mode.
    host1(config-profile)#atm pvc aal5autoconfig cbr 10000 oam 120

    Use the no version to restore the default service type, UBR, on the VC range.
