The disclosure provides a method for detecting a mismatch fault and a Maintenance Endpoint (MEP). The method includes: determining whether there is a Traffic Engineering Service Instance (TESI) configured in a segment, setting a Present Traffic in Segment (PTS) variable, and setting a value of a PTS field included in a Connectivity Check Message (CCM) sent from a Maintenance Endpoint (MEP); receiving the CCM by the MEP, when the value of the PTS field included in the CCM does not coincide with that of the PTS variable, setting, by the MEP, a first mismatch fault indication variable mmCCMreceived to be set; when the first mismatch fault indication variable mmCCMreceived remains set after a first preset time period expires, detecting that a mismatch fault occurs. The method finds timely the mismatch problem occurred in the segment protection of Provider Backbone Bridging-Traffic Engineering (PBB-TE), thereby preventing data loss and service interruption caused by the occurrence of mismatch. |
