acosWANTxUnderrunErrors
Module: ACOS-MIB
OID (symbolic): ACOS-MIB::acosWANTxUnderrunErrors
OID (numeric): 1.3.6.1.4.1.2221.1.1.8.2.1.22
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The total number of frames discarded on this port because of transmitter underrun errors.
What is acosWANTxUnderrunErrors?
This counter records frames discarded because data was not available when the transmitter needed it, leaving the output line idle or incomplete (integer counter). Network engineers use this to detect if the software or data source cannot keep up with the transmit hardware's speed, causing gaps in transmission. A value of 34 over a transfer means the device had to pause 34 times due to lack of outgoing data, reducing overall throughput efficiency.
