Module: Nortel-MsCarrier-MscPassport-AtmBearerServiceMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-AtmBearerServiceMIB::mscAtmIfVpcNrpRxAal5PartialPacketDiscard
OID (numeric): 1.3.6.1.4.1.562.36.2.1.114.4.4.100.1.32
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute is obsolete in P4.2 and has been migrated under Vcd (Vpd) component.
This attribute specifies whether the AAL5 Partial Packet Discard (PPD) feature has been enabled or disabled on the Nrp in the receive direction. This feature allows the NRP to discard the remainder of a cell-forwarded AAL5 frame if a cell of this frame has been discarded due to congestion or usage parameter control (UPC). This increases the 'goodput' of the link, since cells which are only going to be discarded by the AAL5 reassembly are not transmitted.
When this attribute is set to enabled, the PPD feature is applied in the receive direction. It should only be enabled for connections whose end points are performing AAL5 segmentation and reassembly. When this attribute is set to disabled, the PPD feature is not applied to traffic for this connection in the receive direction. When this attribute is set to sameAsTx, the PPD feature for traffic in the receive direction will be configured the same way as it is in the transmit direction. Note that specifying enabled for a non-AAL5 connection will cause all traffic to be discarded once congestion is encountered.
What is mscAtmIfVpcNrpRxAal5PartialPacketDiscard?
An obsolete attribute (migrated to the Vcd/Vpd component in P4.2) that controlled AAL5 Partial Packet Discard in the receive direction on this Vpc Nrp -- enabled, disabled, or sameAsTx to mirror the transmit-direction setting. As with its transmit counterpart, enabling PPD on a non-AAL5 connection drops all traffic under congestion, so an admin should manage this via Vcd/Vpd rather than here on current firmware.
