Network device and network device recognition method

摘要

A network device and network device recognition method are provided. The method includes: receiving a Continuity Check Message (CCM) by a local Maintenance Association End Point (MEP); determining whether the CCM is transmitted from an unknown remote MEP; setting the unknown remote MEP to a dynamic MEP if the CCM is transmitted from the unknown remote MEP; and recording the dynamic MEP and the receiving count of the CCM corresponding to the dynamic MEP in a storage unit.

1. A network device recognition method, comprising following steps:
receiving a Continuity Check Message (CCM) by a local Maintenance Association End Point (MEP); determining whether the CCM is transmitted from an unknown remote MEP; setting the unknown remote MEP as a dynamic MEP if the CCM is transmitted from the unknown remote MEP; recording the dynamic MEP and a receiving count of the CCM corresponding to the dynamic MEP in a storage unit; and activating a first timing mechanism with a first time interval for determining whether the CCM transmitted by the dynamic MEP is received during the first time interval, wherein if the CCM of the dynamic MEP is not received during the first time interval, a record of the dynamic MEP and the receiving count of the CCM corresponding to the dynamic MEP is deleted; if the CCM of the dynamic MEP is received during the first time interval, the receiving count of the CCM is updated.
