PURPOSE: A protection changeover method of a node in a network is provided to improve protection changeover function by optimizing a flush procedure which consumes a lot of time on protection changeover in a network. CONSTITUTION: The generation of a local event is sensed(S200). The block setup or block release of ports is executed according to the local event(S210). A protection changeover message is transmitted(S220). A flush command of a filtering database is generated for a blocked port according to the local event(S230). The flush command of the filtering database is generated for the other ports(S250). [Reference numerals] (AA) Start; (BB) End; (S200) Local event generation sensing; (S210) The block of a port is released or set according to a local event; (S220) A protection switchover message is transmitted; (S230) FDB flush command generation for the blocked port; (S240) Traffic flooding; (S250) FDB flush command generation for ports which exclude the blocked port |
