Module: ACD-PORT-MIB
OID (symbolic): ACD-PORT-MIB::acdPortRxStatsRuntFrames
OID (numeric): 1.3.6.1.4.1.22420.2.9.1.3.2.1.16
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: This is a count of the number of receive packets (or events) detected by this port without SDF detection but with carrier assertion. Packets with valid SFD but no data bytes are also counted as runts. After detecting a runt packet, the update of the RxRunts counter is held off until the next valid packet is received. If multiple runt packets occur between valid packets, the RxRunts counter is incremented only once.
What is acdPortRxStatsRuntFrames?
This counter tracks very short packets (under 64 bytes) that begin arriving but lack a valid start-of-frame marker. Engineers monitor runt frames because they often indicate collisions, electrical noise, or misbehaving devices on congested network segments. If your runt counter increments 5 times per hour, something on the segment is generating electrical artifacts or collision events.
