frpAtmNISapDEtoCLPMapping
Module: CXFrameRelayATMIWF-MIB
OID (symbolic): CXFrameRelayATMIWF-MIB::frpAtmNISapDEtoCLPMapping
OID (numeric): 1.3.6.1.4.1.495.2.1.6.3.52.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Determines which mode will be selected for loss priority mapping in the FR to ATM direction.
Options: mode1 (1): The Discard Eligibility ( DE ) field in the Q.922 core frame shall be copied unchanged into DE field in the FR-SSCS PDU header and mapped to the ATM Cell Loss Priority( CLP ) of every ATM cell generated by the segmentation process of that frame.
mode2 (2): The DE field in the Q.922 core frame shall be copied unchanged into the DE field in the FR-SSCS PDU header and the ATM Cell Loss Priority of every ATM cell generated by the segmentation process of that fame shall be set to a constant value( either 0 or 1 ). The value is decided when the connection is set up, and is used for all cell generated from the segmentation process of every frame, until the ATM connect characteristics are changed.
Default Value: mode1
Configuration Changed: operative
What is frpAtmNISapDEtoCLPMapping?
This object selects how the Frame Relay Discard Eligibility (DE) bit is mapped to the ATM Cell Loss Priority (CLP) bit as frames are segmented into cells going from FR to ATM, with mode1 directly copying DE into CLP on every cell and mode2 instead fixing CLP to one constant value decided at connection setup. An admin changes this from the mode1 default when the network needs consistent cell-loss handling for a circuit rather than per-frame DE-driven marking. For example, selecting mode2 on a circuit ensures every cell generated for it carries the same, pre-negotiated CLP value regardless of individual frames' DE bit.
