wfBisyncTxUnderFlows
Module: Wellfleet-BISYNC-MIB
OID (symbolic): Wellfleet-BISYNC-MIB::wfBisyncTxUnderFlows
OID (numeric): 1.3.6.1.4.1.18.3.4.27.1.1.30
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Number of transmission underflows, device FIFO went empty before next DMA request was granted.
What is wfBisyncTxUnderFlows?
Counts transmit underflows, where the device's FIFO emptied before the next DMA request was granted, a rising counter that points an admin toward a CPU or bus bottleneck starving the transmitter rather than a line-quality issue.
Examples
