A service flow link monitoring method and a related apparatus are provided, where the method includes: sending, by a first MEP according to a first set period, a continuity check message CCM packet corresponding to each monitored service flow link to a second MEP separately, and receiving a CCM packet sent by the second MEP, where the CCM packet carries a set of identifiers of all service flow links monitored by a sending end and identifiers of a service flow link that is used by the sending end for sending the CCM packet; and if a CCM packet that corresponds to at least one service flow link monitored by the second MEP and is sent by the second MEP is not received within a second set period, sending, by the first MEP, fault alarm information. In this solution, one pair of MEPs is used to monitor multiple service flow links, which simplifies complexity and difficulty of configuration and facilitates wide popularization of CFM application. |
