Embodiment
Below with reference to embodiment shown in the drawings, the present invention will be described in detail, but these embodiments are simultaneously
The present invention is not limited, structure that one of ordinary skill in the art is made according to these embodiments, method or functionally
Conversion is all contained in protection scope of the present invention.
Spanning-Tree Protocol (STP, Spanning Tree Protocol) is a kind of two layer-management agreements, and it passes through selectivity
Redundant link in ground clogging networks eliminates double-layer loop, while is also equipped with the function of link backup.Spanning-Tree Protocol with
The development of network and constantly update, from initial STP to RSTP (RSTP, Rapid Spanning Tree
Protocol), then to Multiple Spanning Tree Protocol (MSTP, Multiple Spanning Tree Protocol).
The main distinction between STP, RSTP and MSTP is：STP, it is impossible to fast transferring, even in point-to-point link or
Edge port, it is also necessary to wait 2 times of forward delay time delay, network could restrain；RSTP, according to IEEE
Std 802.1w are defined, by P (proposal)/A (agreement) mechanism Fast Convergent, but all bridges in LAN
Share a spanning tree, it is impossible to block redundant link by VLAN (VLAN, Virtual Local Area Network)；
MSTP, it is allowed to which different VLAN flow is distributed along respective path, so as to provide more preferable load balancing machine for redundant link
System.
Fig. 1 is the system group network figure for being used to determine edge interface in a specific embodiment of the invention.Reference picture 1, it is at this
Assume there are three interchangers in system, in multiple ports of every interchanger, there is port to be connected with another interchanger, between them
There is specific two layer message to interact；Every interchanger all includes the edge port with non-switch connection, such as this three exchanges
Machine passes through oneself edge port connection servers, PC and printer respectively.
Fig. 2 is the schematic flow sheet of the method for determination edge interface disclosed in this invention.Reference picture 2, the present invention is really
Determine the method for edge interface, apply on operation STP, RSTP or MSTP interchanger, this method includes：
Step 201, when being initialized in the port of interchanger, the port is set as designated port and is externally sent specific
Two layer message；
Step 202, if the port is not received by STP, RSTP or MSTP BPDUs of opposite end transmission in setting time,
Then determine that the port is edge port.
Fig. 3 is the detailed process schematic diagram of the method for the determination edge interface based on Fig. 2.Reference picture 3, this method includes：
Step 301, the agreement of interchanger operation is determined.
In this step, the agreement includes STP, RSTP and MSTP.
STP incompatible RSTP and MSTP, that is, STP interchanger nonrecognition RSTP and MSTP BPDUs are run, if received
RSTP or MSTP BPDUs typically directly abandon；RSTP and MSTP compatibility STP, that is, the interchanger for running RSTP and MSTP receive
STP BPDUs, it can be run in a manner of STP.
Step 302, if interchanger runs RSTP and MSTP, when being initialized in the port of interchanger, local terminal is set
Mouth is designated port and externally sends proposal messages.
Step 303, if interchanger runs STP, when being initialized in the port of interchanger, it is specified to set the port
Port simultaneously externally sends STP BPDUs.
In this step, due to RSTP and MSTP compatibility STP, as long as therefore appointing in opposite end support STP, RSTP and MSTP
Meaning is a kind of, can all enter STP patterns, is likely to send STP BPDUs.But if the STP BPDUs priority that the port is sent is higher,
Then opposite end just can not necessarily send out STP BPDUs, and it is edge port to lead to not judge whether.Therefore, it is necessary to ensure that the port is sent out
The priority of the STP BPDUs gone out.
Specifically, after the port enters STP, when the quantity for sending STP BPDUs being set and sending the interval of STP BPDUs
Between, counter can be increased in a switch to be counted to the quantity for sending STP BPDUs.No matter which kind of situation, all at least
Send the STP BPDUs that quantity is set.When the STP BPDUs priority sent is relatively low, opposite end typically directly discard processing, because
This influences little；Under MSTP scenes, the probability of message dropping is relatively low, therefore may be configured as at least sending 2 STP BPDUs, this
It is outer that the interval time for sending STP BPDUs is set for no more than 2 seconds, follow-up STP BPDUs were still sent by former protocol specification.
Step 304, judge STP, RSTP or MSTP BPDUs that opposite end is sent to whether are received in setting time, if
It is that then the port is non-edge port；If it is not, then the port is edge port.
In this step, as long as supporting the interchanger of STP type protocols, the STP classes that quantity is set just can at least be sent
Type message, and non-switch will not send the message of any STP types, wherein STP type messages refer to STP, RSTP or MSTP
Any one in type.
In this way, in setting time, such as 3S, STP, RSTP or MSTP BPDUs that opposite end is sent to inside are received, then the port
For non-edge port；If STP, RSTP or MSTP BPDUs that opposite end is sent to are not received in setting time, the port
For edge port.
As shown in figure 4, present invention also offers a kind of device for being used to determine edge interface, apply in operation STP, RSTP
Or on MSTP interchanger, the device includes：
First processing module 401, during for being initialized in the port of interchanger, set the port as designated port simultaneously
Externally send specific two layer message；
Second processing module 402, if be not received by for the port in setting time STP that opposite end is sent to,
RSTP or MSTP BPDUs, it is edge port to determine the port.
Further, first processing module is specifically used for：Determine the agreement of interchanger operation；If interchanger runs RSTP
And MSTP, when being initialized in the port of interchanger, the port is set as designated port and externally sends proposal messages；
If interchanger runs STP, when being initialized in the port of interchanger, the port is set as designated port and is externally sent
STP BPDUs.
Further, Second processing module is specifically used for：Judge whether receive what opposite end was sent in setting time
STP, RSTP or MSTP BPDUs；If received, the port is non-edge port；If do not received, the port edge
port。
Further, the device also includes：Counter, for being counted to the quantity for sending STP BPDUs.
The present invention is used to determine that the ins and outs of the device of edge interface are similar with foregoing determination edge interface, therefore herein
Do not repeat.
Interchanger can identify that edge port, edge port can be straight under STP, RSTP or MSTP pattern in the present invention
Tap into forwarding state, so as to simplify network calculations, raising efficiency.
Although the present invention is disclosed as above with preferred embodiment, the present invention is not limited to this.Any art technology
Personnel, without departing from the spirit and scope of the present invention, it can make various changes or modifications, therefore protection scope of the present invention should
It is defined when by claim limited range.It is obvious to a person skilled in the art that the invention is not restricted to above-mentioned demonstration
Property embodiment details, and without departing from the spirit or essential characteristics of the present invention, can be with other specific shapes
Formula realizes the present invention.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be non-limiting
