Description: The number of UnderRun Error transmited on this interface
What is e1InterfaceOutUnderRunErrs?
This counter measures transmission underruns—events where the outbound buffer ran empty before a frame finished transmitting. Underrun errors indicate the transmitter cannot feed data fast enough to maintain line rate, causing transmission gaps. This suggests CPU congestion or insufficient memory bandwidth on the device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.45.1.10.2.28.1.1.12 snmpwalk -v2c -c public <target> A3COM-HUAWEI-E1-MIB::e1InterfaceOutUnderRunErrs
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.45.1.10.2.28.1.1.12.1 snmpget -v2c -c public <target> A3COM-HUAWEI-E1-MIB::e1InterfaceOutUnderRunErrs.1
