wfSyncUnderFlowTx
Module: Wellfleet-SYNC-MIB
OID (symbolic): Wellfleet-SYNC-MIB::wfSyncUnderFlowTx
OID (numeric): 1.3.6.1.4.1.18.3.4.5.1.44
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 wfSyncUnderFlowTx?
Running counter of transmit underflows, where the hardware FIFO emptied before the next DMA request was granted; persistent underflows point to a CPU/bus bottleneck feeding this interface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.4.5.1.44 snmpwalk -v2c -c public <target> Wellfleet-SYNC-MIB::wfSyncUnderFlowTx
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.4.5.1.44.1 snmpget -v2c -c public <target> Wellfleet-SYNC-MIB::wfSyncUnderFlowTx.1
