In the related technology, the core of IRF (Intelligent Resilient Framework, intelligent elastic framework) is thought
Want to link together multiple devices, progress is necessary with postponing, and is virtualized into an equipment.Use this virtualization technology
The hardware resource and software processing capability that multiple devices can be gathered, realize multiple devices collaborative work, unified management and not
Interruption is safeguarded.
IRF link failures can cause an IRF equipment to become multiple new IRF equipment.These IRF equipment possess identical
Three layers of IP (Internet Protocol, procotol) address etc. configuration, it will the problems such as causing address conflict, loop, cause
Failure expands in a network.In order to improve the availability of system, a kind of detect and treatment mechanism MAD (Multi-Active is provided
Detection, more active detections).After the division of IRF equipment, MAD detections are capable of detecting when to exist simultaneously multiple IRF in network
Equipment, and corresponding processing is carried out to reduce influence of the IRF equipment division to business.As described below, MAD detections it is main provide with
Lower function：
(1) division detection：Pass through ARP (Address Resolution Protocol, address resolution protocol), ND
(Neighbor Discovery Protocol, Neighbor Discovery Protocol), LACP (Link Aggregation Control
Protocol, Link Aggregation Control Protocol) or BFD (Bidirectional Forwarding Detection, two-way converting
Detect) it whether there is multiple IRF equipment in network to detect.In other words, the MAD detection modes of IRF equipment support include：ARP
MAD detections, ND MAD detections, LACP MAD detections and BFD MAD detections.
(2) clash handle：After the division of IRF equipment, by dividing testing mechanism, IRF equipment can be detected in network and be deposited
In other IRF equipment in active state (Active states indicate that IRF equipment is in normal operating conditions).For ARP
MAD detections/ND MAD detections/BFD MAD detections, clash handle can directly allow main equipment member to number small IRF equipment and be in
Active state continues to work normally；Other IRF equipment transportations are to disabled status (Recovery states).LACP MAD are examined
It surveys, clash handle can first compare the quantity of member device in two IRF equipment, and the IRF equipment more than quantity is in active state, after
Continuous work；Quantity it is few move to disabled status；If number of members is equal, main equipment member numbers at small IRF equipment
In active state, continue to work normally；Other IRF equipment transportations are to disabled status.It can be closed after IRF equipment transportations to disabled status
Other all physical ports (be usually business interface) of all member devices in addition to reserved port in the IRF equipment are closed, with
Ensure that the IRF equipment cannot forwarding service message again.Under default condition, only IRF link physicals port is reserved port, user
It can also set other ports to reserved port by MAD Exclude Interface order lines.
(3) MAD fault recoveries：IRF link failures cause IRF equipment to divide, so as to cause more active state conflicts.Therefore
The IRF links of failure are repaired, as soon as allowing the IRF equipment of conflict to reconsolidate for IRF equipment, MAD failures can be restored.If
Before MAD fault recoveries, there are other failures in the IRF equipment in active state, then disabling shape can be first enabled by order line

MAD is detected, thus after the division of IRF equipment, it will detect the port for closing IRF for equipment by MAD.
In the related technology, if a DR equipment in DRNI systems is IRF equipment, Keepalive links and IPL chains
Road is attached by the way of across frame polymerization.Due to the IPP mouthfuls of ports that do not closed by MAD detections for system setting, and
The port of Keepalive links is the port that do not closed by MAD detections by configuring.After IRF equipment divides, it will logical
The port that MAD detections close IRF for equipment is crossed, and IRF beats for the IPP mouths of equipment, the port of Keepalive links or normally
It opens.Thus IRF equipment division after, it will occur IRF main equipments and IRF for equipment the corresponding physical port of IPP mouths with
The corresponding physical port in port of Keepalive links is all to open, and DRNI systems will will appear address conflict, loop etc. and ask

Message.Equipment D ignores the message, and the Port3 and Port4 that receive the equipment D of the message is kept to open.Thus regardless of aggregation port
For dynamic aggregation or static polymerization, IPL links and Keepalive links are between device A and equipment D, and DRNI systems can be just
The problems such as often work is not in address conflict, loop.
As another example, when being identified as 1, indicate that IRF is closed for equipment by IRF MAD detections；When being identified as 2,
Indicate that DRNI is closed from equipment by DRNI MAD detections；When being identified as 3, indicate that the equipment in DRNI systems is not examined by MAD
It surveys and closes.It is carried as shown in figure 5, Port1, Port2 of device A are sent at interval of preset duration to Port3, Port4 of equipment D
The message of the mark of MAD testing results for indicating device A.Port5, Port6 of equipment B is at interval of preset duration to equipment
Port7, Port8 of D sends the message for the mark for carrying the MAD testing results for indicating equipment B.In the mark that message carries
In the case of 1, the physical port that equipment D will receive the equipment D of the message is closed.It is identified as 2 or 3 what message carried
In the case of, equipment D ignores the message, keeps the physical port for receiving the equipment D of the message.
For another example as shown in figure 5, when the link failure between device A and equipment B, after causing IRF equipment to divide, equipment B is logical
IRF MAD detections are crossed to close, and device A is not closed by IRF MAD detections, and work is still kept.Thus equipment B detect it is logical
It crosses in the case that IRF MAD detection closes, generates the report carried for indicating mark that equipment B is closed by IRF MAD detections
Text generates the message for carrying that the state value of mark is 1.Port5, Port6 of equipment B is sent to Port7, Port8 of equipment D
Carry the message that the state value of mark is 1.The Port7 and Port8 that equipment D will receive the equipment D of the message are closed.And device A
In the case where detecting not through IRF MAD detection closings, generates and carry for indicating that device A is not detected by IRF MAD
The message of the mark of closing generates the message for carrying that the state value of mark is 3.Port1, Port2 of device A are to equipment D's
Port3, Port4, which are sent, carries the message for being identified as 3.Equipment D ignores the message, keeps the equipment D's for receiving the message
Port3 and Port4 is opened.Thus no matter aggregation port is dynamic aggregation or static polymerization, IPL links and Keepalive links are equal
It is between device A and equipment D, DRNI systems can work normally, the problems such as being not in address conflict, loop.
For another example as shown in figure 5, after IPP mouthfuls (such as aggregation port 1) is closed, equipment D is closed by DRNI MAD detections
It closes, thus device A or equipment B are raw in the case where detecting that IPP mouthfuls of closings cause equipment D to be closed by DRNI MAD detections
At the message carried for indicating equipment D by the mark of DRNI MAD detection closings, that is, generate the message for carrying mark 2.If
The Port2 of standby A is sent to the Port4 of equipment D carries the message for being identified as 2.Equipment D ignores the message, and holding receives the report
The Port4 of the equipment D of text is opened.Thus the Keepalive links between device A and equipment D can work normally, and equipment D is logical
It crosses DRNI MAD detections to close, the problems such as being not in two main equipments, be not in address conflict, loop.
