atmIfVptVpdTmTxWredMode
Module: Nortel-Magellan-Passport-AtmCoreMIB
OID (symbolic): Nortel-Magellan-Passport-AtmCoreMIB::atmIfVptVpdTmTxWredMode
OID (numeric): 1.3.6.1.4.1.562.2.4.1.114.9.2.2.100.1.77
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute specifies the activation of weighted random early detection (WRED) functionality. WRED is only available on ATM IP FPs. On CQC-based ATM FPs, this attribute is ignored. If txPacketWiseDiscard is set to disabled this attribute is ignored. This attribute is not applicable for Vpts or Vpt Vccs.
WRED is applied in the transmit direction for this connection. WRED function should be enabled only for connections which are transferring TCP/IP traffic. WRED acts to prevent synchronization of multiple TCP/IP sources by randomly discarding a small percentage of frames when transmit queue congestion reaches the designated level. W-RED may also be used to differentiate service on VCC's by preferentially discarding one VCC before another. Discards start at 0% of cells, when the queue is part-way to the Early Packet Discard (EPD) threshold, and rise to 100% of cells discarded at the EPD threshold. WRED discards all the cells in a frame.
If this attribute is set to enabled, WRED is enabled for all applications linked to the given Vcc. If it is set to perFlow, each TCP application has individual control over whether to enable or disable WRED
If txPacketWiseDiscard is set to disabled, or if this attribute is set to disabled, WRED functionality is disabled.
If WRED is active, it is visible in the Vcc/Vpc Tm txPacketWiseDiscard operational attribute.
