Provided are a method and device for monitoring Operation Administration and Maintenance (OAM) performance. The method includes that: a switch receives OAM performance monitoring rules sent by a controller; the switch receives OAM performance monitoring messages, and filters the OAM performance monitoring messages according to the OAM performance monitoring rules; the switch reports each first OAM performance monitoring message obtained by filtering to the controller for processing, wherein the first OAM performance monitoring message is a message, conforming to the OAM performance monitoring rules, in the OAM performance monitoring messages. The technical solution can reduce controller performance consumption and excessive occupation of control channel bandwidth caused by reporting performance monitoring delay measurement results and packet loss measurement results.
