Description: This counter is incremented when a station detects the absence of transitions for five half-bit timers (burst-five error).

What is a3ComSysTokenRingPortBurstErrors?

This counter increments when the port detects a burst-five error—absence of valid signal transitions for five half-bit periods—indicating loss of synchronization. Engineers watch this counter for signs of electrical signal degradation, cable damage, or media attachment unit (MAU) failures on the token ring. A sudden increase from 0 to 20 errors suggests a serious physical layer fault requiring troubleshooting.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.29.4.13.2.1.9
snmpwalk -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-TOKEN-RING-MIB::a3ComSysTokenRingPortBurstErrors

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.29.4.13.2.1.9.1
snmpget -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-TOKEN-RING-MIB::a3ComSysTokenRingPortBurstErrors.1
