acdPortRxStatsFalseCRS
Module: ACD-PORT-MIB
OID (symbolic): ACD-PORT-MIB::acdPortRxStatsFalseCRS
OID (numeric): 1.3.6.1.4.1.22420.2.9.1.3.2.1.18
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 with a false carrier (SSD1 not followed by SSD2). After detecting a false carrier, update of the RxFalseCRS counter is held off until the next valid packet is received. If multiple false carrier events occur between valid packets, the RxFalseCRS counter is incremented only once.
What is acdPortRxStatsFalseCRS?
This counter tracks false carrier signals detected by the port's physical layer, where the start marker isn't followed by the expected data marker. Network engineers investigate false carriers because they indicate electrical noise, loose connections, or a degraded physical medium. If this counter increments frequently, like 20 times per hour, you may have electromagnetic interference (EMI) or a failing transceiver.
