Example, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to explain this hair
It is bright, it is not intended to limit the present invention.
Based on system architecture shown in FIG. 1, Fig. 2 shows a kind of link failure processing sides provided in an embodiment of the present invention
Method, suitable for the blade server system including the first exchange system and the second exchange system, this method comprises:
Step 201, the first exchange system detects upper level link state；
Step 202, when the first exchange system detects that upper level link disconnects, by the first exchange system and blade server
The state of the second line of a couplet port of connection is set as failing, to trigger the first line of a couplet port that blade server will couple with the first exchange system
It is set as standby port, sets master port for the first line of a couplet port that blade server couples with the second exchange system.
In the embodiment of the present invention, blade server system includes two exchange systems, and the first exchange system is exchanged with second
The title of system is only used for two exchange systems of difference, and not refers in particular to some exchange system.In the embodiment of the present invention, blade
The port that server is carrying out data transmission is master port, and the exchange system connecting with the master port of blade server can be knife
Any exchange system in piece server system is assumed in the embodiment of the present invention to connect with the master port of blade server at present
Exchange system is the first exchange system.It is assumed that the exchange system connecting at present with the master port of blade server is the second friendship
System is changed, in following embodiments by taking the exchange system connecting at present with the master port of blade server is the first exchange system as an example
It is introduced.
Based on it is above-mentioned it is assumed that in the embodiment of the present invention when the first exchange system detect upper level link disconnect when, by first
The state for the second line of a couplet port that exchange system couples with blade server is set as failing, at this time the first exchange system and blade service
The second line of a couplet link of device connection disconnects, and the master port connecting at this time with the first exchange system can be detected in blade server cannot be normal
Work is in failure state, then the flag bit of the port connecting with the first exchange system is modified by blade server,
The master port currently connecting with the first exchange system is changed to standby port, more by the standby port connecting with the second exchange system
Be changed to master port, at this point, the data in blade server are from master port, and the second exchange system by being connect with master port into
Row transmission.
Preferably, in above-mentioned steps, while the first exchange system detects upper level link state, the second exchange system
In detection upper level link state, and they are independent from each other, i.e. the first exchange system detect the work of upper level link state with
Second exchange system is also carried out separately in the work of detection upper level link, will not mutually be interfered.And when the second exchange
When system detection is disconnected to upper level link, set the state for the second line of a couplet port that the second exchange system couples with blade server to
Failure couples the first exchange system with blade server when this movement detects that upper level link disconnects with the first exchange system
The state of second line of a couplet port to be set as failure be also independently to carry out, will not interfere between each other.
Preferably, the first exchange system can be periodically detected upper level link state, the second exchange system is periodically detected
Join link state.
In above-mentioned steps 202, the second line of a couplet port status that the first exchange system is coupled with all blade servers is arranged
After failure, blade server sets first line of a couplet port couple with the first exchange system to for port, by blade server
The first line of a couplet port coupled with the second exchange system is set as master port, the master that the data in blade server pass through blade server
Port and the second exchange system connecting with master port are transmitted.If at this moment, the first exchange system detects first line of a couplet chain
When line state restores, then the state for the second line of a couplet port that the first exchange system couples with blade server is set as activating, i.e. table
The second line of a couplet port for showing that the first exchange system is connect with blade server can also work normally, but due to blade server at this time with
The transmission link of second exchange system connection is still in normal work, therefore, blade server still normal transmission data at this time,
The master port state connecting with the second exchange system worked normally at this time can't be changed, until blade service
When device detects the master port cisco unity malfunction connecting with the second exchange system, the end that can will just be connect with the second exchange system
Mouth switches to standby port from master port, by the port connecting with the first exchange system from standby port switching to master port, so that knife
The data of piece server transport are transmitted by master port and the first exchange system connecting with master port.
On the other hand, it is assumed that current blade server passes through master port, and the second exchange system connecting with master port
Carry out data transmission, if the second exchange system detects that the upper level link of the second exchange system disconnects, by the second exchange system
The state of the second line of a couplet port coupled with blade server is set as failing, and blade server detects blade server and second
The master port Status Change of exchange system connection is failure, then blade server is by the shape for the port connecting with the second exchange system
State is changed to standby port from master port, and the state for the port connecting with the first exchange system is changed to master port.To realize
Network redundancy switches to another link, in time when network link breaks down with the safety of improve data transfer.
Preferably, each exchange system in blade server system in the first exchange system and the second exchange system is upper
Joining port can be to be multiple, preferably, being introduced by taking the first exchange system as an example in the embodiment of the present invention, those skilled in the art
Member is it is found that the second exchange system is identical as the setting in the first exchange.
It based on above-mentioned premise, is illustrated with the first exchange system, preferably, the first line of a couplet port of the first exchange system is M
It is a, N number of control group, N >=M, the corresponding one or more control groups in each first line of a couplet port are provided in the first exchange system；Each control
The part second line of a couplet port of the first exchange system is configured in processed group, a second line of a couplet port is only configured at a control group.Preferably,
The IP address of the blade server of first exchange system connection belongs to M network segment, what the blade server of same network segment was connected
The second line of a couplet port of first exchange system is arranged in same control group.Specifically, under application scenes, in same
The blade server of network segment executes same business, by the blade server of the same business of execution connected on the first exchange system
Port is correspondingly arranged in same control group, when the first exchange system detects that upper level link disconnects, according to the first line of a couplet of disconnection
First line of a couplet port corresponding to link determines corresponding control group, sets the state of the second line of a couplet port in the control group determined to
Failure.
By taking the first exchange system as an example, the configuration flow in the first exchange system is introduced.The power-up of first exchange system, is in
Normal operating conditions, protocol port is opened in the first exchange system inside, in order to allow to configure to the first exchange system.It will
The first line of a couplet port of upper level link in first exchange system is configured to the monitoring port for needing to monitor, and corresponds to the first exchange system
The second line of a couplet port configuration control group that system is connect with blade server, and configure monitored first line of a couplet port pass corresponding with control group
System.
Likewise, the first line of a couplet port of the second exchange system is M, it is provided with N number of control group in the second exchange system, N >=
M, the corresponding one or more control groups in each first line of a couplet port；The part second line of a couplet end of the second exchange system is configured in each control group
Mouthful, a second line of a couplet port is only configured at a control group.Preferably, the IP address of the blade server of the second exchange system connection
Belong to M network segment, the second line of a couplet port for the second exchange system that the blade server of same network segment is connected is arranged on same control
In processed group.When the second exchange system detects that upper level link disconnects, according to first line of a couplet port corresponding to the upper level link of disconnection
It determines corresponding control group, the state of the second line of a couplet port in the control group determined is set as failing.
By taking the first exchange system as an example, for example, the first line of a couplet port of the first exchange system is assumed to be two, and assumes the
There are 14, and the net of the IP address according to blade server in the second line of a couplet port that one exchange system is connect with blade server system
Section, the second line of a couplet port for the first exchange system that different blade servers are connected is arranged in same control group, for example, false
If the IP address of 14 blade servers is belonging respectively to M network segment, then M control group is accordingly set, by the blade of same network segment
The second line of a couplet port for the first exchange system that server is connected is arranged in same control group.Each first line of a couplet port is one corresponding
Or multiple control groups, specifically, the data that blade server is transmitted upwards by the first exchange system may be held by two
It mouthful realizes, for example, it is assumed that blade server 1 to 7, carried out data transmission by the first line of a couplet port 1 of the first exchange system,
And blade server 8 to 14 is carried out data transmission by the first line of a couplet port 2 of the first exchange system, it is assumed that blade server 1
It is belonging respectively to control group 1 and control group 2 to 7, and blade server 8 to 14 belong to control group 3, then the corresponding control in first line of a couplet port 1
Processed group 1 and control group 2；First line of a couplet port 2 corresponds to control group 3.
Based on above-mentioned false example, when the first exchange system detects that upper level link disconnects, according to the upper level link of disconnection
Corresponding first line of a couplet port determines corresponding control group, and the state of the second line of a couplet port in the control group determined is set as losing
Effect.When first line of a couplet port 1 is broken down, the first exchange system of configuration in the corresponding control group 1 in first line of a couplet port and control group 2
The state of second line of a couplet port is both needed to be set as failure state, and control group 1 and control group 2 respectively correspond blade service 1 to 7 at this time, because
This, blade server 1 to 7 sets standby port for the port connecting with the first exchange system at this time, will exchange system with second
The port of system connection is set as master port.
Specifically, the upper level link state of the first exchange system, the first exchange system be can detect in the embodiment of the present invention
The first line of a couplet port status for detecting the first exchange system determines that upper level link disconnects when detecting first line of a couplet port status to fail.
First line of a couplet port in the first exchange system and the second exchange system and second line of a couplet port in blade server system is equal
There are two kinds of working conditions, that is, fail and activate, and port failure indicates the port cisco unity malfunction, with the first exchange system
For be introduced, there is the group of following one or more in the case where first line of a couplet port cisco unity malfunction in the first exchange system
It closes:
As shown in fig. 1, the first exchange system 106 with the first outside switching equipment 111 is coupled first exchanges system
105 cisco unity malfunction of first line of a couplet port, 106 cisco unity malfunction of the first exchange system, the first exchange system 106 on system and
Outside 117 cisco unity malfunction of upper level link that one outside switching equipment 111 is coupled, the first exchange system 106 and first
The failure of port 110 on the first outside switching equipment 111 that switching equipment 111 is coupled, the first outside switching equipment
111 break down.
