Embodiment

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

Embodiment one

With reference to the method flow diagram that figure 1, Fig. 1 is a kind of ether port auto-negotiation that the embodiment of the present invention one provides.Described method comprises:

Step 101, the ether port chip A of the first communication equipment sets up link by the auto-negotiation mode of the first port mode in the port mode list that pre-sets and the ether port chip B of second communication equipment, wherein, described first communication equipment is connected with the ether port chip of other communication equipments by described ether port chip A, described ether port chip A supports the port mode of at least one IEEE802.3 normalized definition, the ether port chip of other communication equipments described only supports a kind of port mode of IEEE802.3 normalized definition, described second communication equipment is one in other communication equipments described, the port mode that described port mode list is supported for described ether port chip A is for carrying out the sequential list of port negotiation,

As shown in Figure 2, first communication equipment is connected with communication equipment 1-n by backboard, ether port chip A supports 100BASE-FX pattern and 1000BASE-SX pattern, then port mode list be exactly described ether port chip A support 100BASE-FX pattern and 1000BASE-SX pattern for carrying out the sequential list of port negotiation, such as, can arrange according to first carrying out port negotiation by 100BASE-X port mode in mode list, link is set up with communication equipment 1-n again by the order of 1000BASE-FX port mode, described 100BASE-FX pattern and 1000BASE-SX pattern are the patterns of IEEE802.3 normalized definition, wherein, 1000BASE-SX has definition auto-negotiation mode in IEEE802.3 specification, but 100BASE-FX does not define auto-negotiation mode in IEEE802.3 specification.

Each ether port chip of ether port chip 1-n only supports the port mode of a kind of IEEE802.3 normalized definition or 100BASE-FX pattern, or 1000BASE-SX pattern.The port of ether port chip A, by the software control of the control and management module of the first communication equipment, performs the auto-negotiation flow process shown in Fig. 3.

Can be preferred, when the port mode of described IEEE802.3 normalized definition has definition auto-negotiation mode in IEEE802.3 specification, then ether port chip A sets up link by the ether port chip B of the second communication equipment in the auto-negotiation mode that defines in IEEE802.3 specification and other communication equipments described.When the port mode of described IEEE802.3 normalized definition does not define auto-negotiation mode in IEEE802.3 specification, then ether port chip A sets up link by the auto-negotiation mode of the mutual special packet sequence of ether port chip B with the second communication equipment in other communication equipments described.

Wherein, when not defining auto-negotiation mode in IEEE802.3 specification, the auto-negotiation mode of described mutual special packet sequence, specifically comprise: the special packet sequence of the port mode of the described IEEE802.3 normalized definition of mutual IEEE802.3 normalized definition, if the received also verification succeeds of described special packet sequence, then judge to set up link success, otherwise judge to set up link failure.Concrete, judge whether port can set up link success (if receive and verify correctly, think and set up link successfully, otherwise think set up link failure) according to IEEE802.3 normalized definition by the mutual special packet sequence of ether port (such as IDLE code stream) be connected with opposite end.Described IDLE code stream is the code stream sequence defined inside ieee specification, (namely force to arrange the parameters such as speed, duplex, Flow Control under pressure port mode for ether port, but not to be operated by auto-negotiation according to normalized definition determine port parameter), information interaction is carried out, to determine whether normally (link up) port connects with Peer-Port.Namely, described ether port chip A is according to the mutual special packet sequence of ether port chip B of the second communication equipment in IEEE802.3 normalized definition and other communication equipments described, judge whether described ether port chip A can set up link with the ether port chip B of the second communication equipment in other communication equipments described by described special packet sequence, if the received also verification succeeds of described special packet sequence, then judge to set up link success link up, otherwise judge set up link failure link down, wherein link down represent set up port failure.

Such as, as shown in Figure 3, when ether port chip A sets up link according to the port mode list pre-set by the ether port chip 1 of 1000BASE-SX pattern and communication equipment 1, because described 1000BASE-SX pattern has definition auto-negotiation mode in IEEE802.3 specification, then ether port chip A sets up link by the auto-negotiation mode of 1000BASE-SX port mode that defines in IEEE802.3 specification and the ether port chip 1 of described communication equipment 1.When ether port chip A sets up link according to the port mode list pre-set by the ether port chip 1 of 100BASE-FX pattern and communication equipment 1, because described 100BASE-FX pattern does not define auto-negotiation mode in IEEE802.3 specification, then ether port chip A is by setting up link with the auto-negotiation mode of the mutual special packet sequence of the ether port chip 1 of communication equipment 1.Herein, second communication equipment is communication equipment 1, and ether port chip B is ether port chip 1.

Step 102, if described ether port chip A sets up link success by the auto-negotiation mode of described first port mode and described ether port chip B, then determines that described first port mode is the port mode of described ether port chip B.

Wherein, same, the auto-negotiation mode of described first port mode has two kinds of situations:

If described first port mode defines auto-negotiation mode in IEEE802.3 specification, then the auto-negotiation mode of described first port mode is the auto-negotiation mode defined in IEEE802.3 specification; As shown in Figure 2,1000BASE-SX pattern has definition auto-negotiation mode in IEEE802.3 specification, then the auto-negotiation mode of 1000BASE-SX pattern is held consultation with the auto-negotiation mode of the ether port chip of the equipment of opposite end according to IEEE802.3 normalized definition.

If described first port mode does not define auto-negotiation mode in IEEE802.3 specification, then the auto-negotiation mode of described first port mode is the auto-negotiation mode of mutual special packet sequence.As shown in Figure 2,100BASE-FX pattern does not define auto-negotiation mode in IEEE802.3 specification, then the auto-negotiation mode of 100BASE-FX pattern is special packet sequence mutual with the ether port chip of the equipment of opposite end.

Preferably, as the ether port chip Blink up of the second communication equipment in the mode and other communication equipments described of the auto-negotiation defined during described ether port chip A is by the IEEE802.3 specification of the first port mode, then determine that described first port mode is the mode of operation of the ether port chip B of second communication equipment in other communication equipments described, wherein link up represents auto-negotiation success, successfully sets up link.Such as, as shown in Figure 2, the auto-negotiation mode of the 1000BASE-SX pattern defined in ether port chip A is with IEEE802.3 specification and the ether port chip 2 of communication equipment 2 set up link, because the port mode of the ether port chip 2 of communication equipment 2 is 1000BASE-SX patterns, then link up.

Preferably, when described ether port chip A is by the ether port chip link up of the second communication equipment in the auto-negotiation mode of mutual special packet sequence and other communication equipments described, then determine that described first port mode is the mode of operation of the ether port chip B of second communication equipment in other communication equipments described.Such as, as shown in Figure 2, when ether port chip A sets up link with the ether chip 1 of the mode of mutual special packet sequence and communication equipment 1 under 100BASE-FX port mode, link link up, then determine that the port mode of the ether port chip 1 of communication equipment 1 is 100BASE-FX pattern.

Step 103, if described ether port chip A sets up link failure by the auto-negotiation mode of described first port mode and described ether port chip B, then be switched to described next port mode of port mode list, link is set up by next port mode described and described ether port chip B, until described ether port chip A sets up link by the auto-negotiation mode of the second port mode and described ether port chip B, then determine that described second port mode is the port mode of described ether port chip B.

Concrete, when described ether port chip A sets up link failure by the ether port chip B of the second communication equipment in the mode of the auto-negotiation of the first port mode and other communication equipments described, i.e. link down, then described ether port chip A is switched to next port pattern according to the port mode list pre-set from described first port mode, link is set up by next port mode described and described ether port chip B, if link establishment is unsuccessful, then continue the pattern of next port be again switched in port mode list, until described ether port chip A sets up link success by the auto-negotiation mode of the second port mode and described ether port chip B, then determine that described second port mode is the port mode of described ether port chip B.

Such as, can shown in reference diagram 4, the first communication equipment is cassete exchange machine, and communication equipment 1 ~ n can be cassete exchange machine or server etc., they, by optical fiber or passive cable interconnection, do not limit for the particular type of communication equipment and interconnection mode in the embodiment of the present invention.First communication equipment is connected with communication equipment 1 ~ n, and ether port chip A supports 100BASE-FX, 1000BASE-SX, 10GBASE-CR, 10GBASE-SR pattern, and ether port chip 1 ~ n all only supports a kind of above-mentioned 4 kinds of port modes.10GBASE-SR, 10GBASE-CR, 100BASE-FX do not define auto-negotiation mode in IEEE802.3 specification, and 1000BASE-SX is auto-negotiation mode at IEEE802.3 normalized definition.Here port mode list be exactly described ether port chip A support 10GBASE-SR, 10GBASE-CR, 1000BASE-SX, 100BASE-FX pattern is for carrying out the sequential list of port negotiation, such as, be assumed to be in the present embodiment according to 10GBASE-SR, 10GBASE-CR, 1000BASE-SX, 100BASE-FX order set up link with communication equipment 1-n.

Auto-negotiation process in often kind of port mode can with reference to figure 5.Set up link for the ether port chip 1 of the ether port chip A of the first communication equipment and communication equipment 1 below and the embodiment of the present invention is described.

First ether port chip A sets up link according to the ether port chip 1 sequentially passing through 10GBASE-SR pattern and communication equipment 1 of port mode list, auto-negotiation mode is not defined in IEEE802.3 specification, if then according to IEEE802.3 specification and the mutual specific sequence of message of ether port chip 1, port judges whether ether port can receive and verify correct by link up(, thinks that link up is successful, otherwise think link down), if linkup success, determines that the port mode of the ether port chip 1 of communication equipment 1 is 10GBASE-SR pattern, arranging this port is 10GBASE-SR pattern, port normally works.

If link can not link up, then think auto-negotiation failure, ether port chip A is switched to next port mode 10GBASE-CR pattern in port mode list.Concrete, according to port mode list, the port mode of ether port chip A can be set to 10GBASE-CR pattern by control and management module.

Under 10GBASE-CR pattern, IEEE802.3 specification does not define auto-negotiation mode yet, if ether port chip A is also by judging that whether link up(receives and verifies correct link, thinks that link up is successful according to IEEE802.3 specification and the mutual specific sequence of message of Peer-Port, otherwise think link down) judge auto-negotiation whether success, operate same 10GBASE-SR.

If link can not link up, then think that auto-negotiation is failed, ether port chip A is switched to next the port mode 1000BASE-SX pattern in port mode list, under 1000BASE-SX pattern, IEEE802.3 normalized definition auto-negotiation mode, ether port chip A then carries out auto-negotiation with Peer-Port according to the auto negotiation mode of IEEE802.3 normalized definition, if consult successfully, then determine that Peer-Port is 1000BASE-SX pattern, this port working is set in 1000BASE-SX pattern, port link up, working properly.

If the failure of 1000BASE-SX auto-negotiation, then enter 100BASE-FX pattern, if be also by judging whether that link up(receives and verify correct according to the mutual specific sequence of message of IEEE802.3 specification and Peer-Port, thinking that link up is successful under this pattern, otherwise think link down) judge that whether auto-negotiation is successful.

If the failure of 100BASE-FX auto-negotiation, then come back to 10GBASE-SR pattern according to port mode list.Certainly, also after all of the port pattern in port mode list all attempted, no longer can carry out auto-negotiation trial, and provide alarm or prompting, show that cannot mate suitable port mode with opposite equip. successfully sets up link.

The all of the port of ether port chip A all performs such auto-negotiation flow process, to determine the port mode of opposite end communication equipment, thus arranges each ether port that ether port chip A is connected with communication equipment 1-n.

In this example by the software free setting of control and management module, can there is not restriction in the port mode transfer sequence of ether port chip A.Ether port mode can also support 10GBASE-LR, and in IEEE802.3 specification, later release increases the port mode of definition, as long as the interface homomorphosis of the port mode in its interface form and this example, is not construed as limiting.

In the embodiment of the present invention, the ether port chip A of described first communication equipment by the order in the port mode list that pre-sets from the first port mode in the various ports pattern of described support, link is set up by the auto-negotiation mode of present port pattern and the ether port chip B of second communication equipment, until ether port chip A and described ether port chip B sets up link, then determine that described present port pattern is the port mode of described ether port chip B.Thus the physical port realizing controlling ether port chip switches, and different port modes is next carries out auto-negotiation with Peer-Port, give full play to the chip characteristics supporting multiport pattern, enhance between device interior pattern and interconnect between interconnection, plate, the flexibility interconnected between equipment and equipment, avoid complexity and the expense that setting forced by software, and avoid manually operated trouble, simplify the deployment of equipment.
