rptrMonitorPortAlignmentErrors
Module: SNMP-REPEATER-MIB
OID (symbolic): SNMP-REPEATER-MIB::rptrMonitorPortAlignmentErrors
OID (numeric): 1.3.6.1.2.1.22.2.3.1.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This counter is incremented by one for each frame received on this port with the FCSError and FramingError signals asserted and CollisionEvent signal deasserted and whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize (Ref: IEEE 802.3 Std, 4.4.2.1). If rptrMonitorPortAlignmentErrors is incremented then the rptrMonitorPortFCSErrors Counter shall not be incremented for the same frame.
A discontinuity may occur in the value when the value of object rptrMonitorPortLastChange changes.
The approximate minimum time for rollover of this counter is 80 hours at 10Mb/s.
What is rptrMonitorPortAlignmentErrors?
This OID holds a counter that increments when frames arrive with corrupted formatting and checksum errors, indicating the frame is malformed. It reveals physical layer problems like cable damage or electromagnetic interference affecting data integrity on the port. A network technician seeing this counter increase would suspect a bad network cable, loose connector, or nearby electrical equipment causing signal corruption.
