Abstract

The invention provides a method for extending port serial numbers and a switch; wherein the method comprises that a first switch determines the bits in a media access control MAC address in an appointed bridge identifier ID, wherein the bits are used for identifying the first switch; the first switch calculates the bits for extending the port serial numbers according to the bits for identifying the first switch; and the first switch combines the bits for extending the port serial numbers and the original bits for appointed ports so as to obtain the new bits for appointed ports. According to the method and the switch, the problem of insufficient STP (Spanning Tree Protocol) protocol port serial numbers when the number of the ports is high in a super virtual switch network is solved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for extending port numbering and a switch. Background technique [0002] In the data link layer switching network, when the switch is transmitting messages, once there is a loop in the network, some messages will continue to proliferate and circulate infinitely in the loop network, which will cause the switch to repeatedly receive the same message This reduces the packet processing capability. [0003] In order to avoid the above problems, the Spanning Tree Protocol (English: SpanningTree Protocol, referred to as: STP) came into being. This protocol is established according to the Institute of Electrical and Electronics Data layer physical loop. Switches running this protocol discover loops in the network by exchanging information with each other, and selectively block certain ports. Finally, the loop network structure is built into a loop-free tree network str...
