pportInErrors
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::pportInErrors
OID (numeric): 1.3.6.1.4.1.277.1.4.2.1.19
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The total number of inbound frames that contained erroneous headers (e.g., illegal or unknown DLCIs).
What is pportInErrors?
This counts inbound frames on this physical port that were rejected specifically because their header was erroneous, for example referencing an illegal or unknown DLCI. A rising count here on a frame relay port usually means either a misconfigured DLCI on the far-end router or a PVC that was deleted on this switch while the remote end kept sending to it. Seeing pportInErrors climb right after decommissioning a PVC on this port would confirm the far-end CPE has not yet been reconfigured and is still sending frames to the now-unknown DLCI.
