Embodiment Construction
[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0065] The method provided by the present invention is as figure 1 As shown, it mainly includes the following processes:
[0066] Step 101: The stacking system, as a logical device, participates in the GM election of the external PTP network and the establishment of a synchronous spanning tree.
[0067] Step 102: Each member device in the stack system sends an internal notification message through the stack port to elect a GM and establish a synchronous spanning tree within the stack system; wherein, if the stack system is elected as a non-GM in the external PTP network, the slave service port The member device where it is located is elected as the GM.
[0068] In this step, if the stacking system is elected as the GM in the external PTP network...
