The method that auto-negotiation AM sends sequence can be to continuously receive multiple 2nd AM values and at least one the 3rd AM value if met,
The multiple AM values for determining the acquisition are that auto-negotiation AM sends sequence.If conditions are not met, multiple AM values that then determination obtains are not
Auto-negotiation AM sends sequence.
For example, as shown in figure 8, when receiving device receive form be 5X5X5X1X3X3X3X2X data 803 when, first
It is split, continuously acquires multiple AM values 801, i.e., 55513332.Judge whether to continuously receive 3 the 2nd AM values and 1
3rd AM value, i.e., 5551.First four of multiple AM values of the acquisition are 5551, that is, continuously receive 3 the 2nd AM values and 1 third
AM value, satisfaction continuously receive multiple the 2nd AM values and at least one the 3rd AM value, so determining that it is that auto-negotiation AM sends sequence
Column obtain auto-negotiation AM and send sequence.
405, sequence is sent according to the auto-negotiation AM of PCSL each in the sending device, obtains PCSL in the sending device and ties up
Determine information.
Specifically, which includes the following steps 405A-405F:
405A, send sequence to the auto-negotiation AM of each PCSL and decompose, obtain the first subsequence, the second subsequence,

Port.
405E, from the 4th subsequence, extract the corresponding AM value of the PCSL.
According to above-mentioned steps 405A to 405E, which can obtain this PCSL pairs of each PCSL of the sending device
AM value, the first AM value, the 2nd AM value and the 3rd AM value answered.For example, as shown in figure 8, the auto-negotiation AM hair that sending device is sent
Send sequence 801 be 55513332 when, it is decomposed, 555,1,333,2 four subsequences, the respectively first sub- sequence are obtained
Column 804, the second subsequence 805, third subsequence 806 and the 4th subsequence 807.It is extracted as the 2nd AM value by 5,1 is extracted as
3rd AM value is extracted as the first AM value for 3, is extracted as the corresponding AM value of the PCSL for 2.
405F, according to the corresponding AM value of the PCSL, the first AM value, the 2nd AM value and the 3rd AM value, obtain the hair
Send PCSL binding information in equipment.
