portFlowCtrlCfg
Module: A3COM-PRIVATE-MIB
OID (symbolic): A3COM-PRIVATE-MIB::portFlowCtrlCfg
OID (numeric): 1.3.6.1.4.1.43.35.8.3.1.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: (1) Flow control mechanism is enabled. If the port type is hundredBaseTX or thousandBaseSX: When the port is operating in halfDuplex mode, the port uses backPressure flow control mechanism. When the port is operating in fullDuplex mode, the port uses IEEE 802.3x flow control mechanism. If the port type is hundredBaseFX: When the port is operating in halfDuplex mode, the port uses backPressure flow control mechanism. When the port is operating in fullDuplex mode, Flow control mechanism will not function. (2) Flow control mechanism is disabled. (3) Flow control mechanism is backPressure. when the port is in fullDuplex mode.This flow control mechanism will not function. (4) Flow control mechanism is IEEE 802.3x flow control. when the port is in halfDuplex mode.This flow control mechanism will not function. hundredBaseTX and thousandBaseSX port can be set as: enabled(1), disabled(2), backPressure(3), dot3xFlowControl(4). hundredBaseFX port can be set as: enabled(1), disabled(2), backPressure(3). The actual flow control mechanism is used given by portFlowCtrlStatus.
What is portFlowCtrlCfg?
This OID shows whether flow control is enabled and which mechanism is configured (backpressure or 802.3x). Proper flow control prevents packet loss during congestion by signaling devices to pause transmission temporarily. Setting this to '802.3x' ensures compatibility with modern full-duplex switched environments.
