The embodiment of the present invention provides another mainboard network connectivty test method, and Fig. 4 is mainboard network-in-dialing of the present invention
The flow chart of property test method embodiment three, as shown in figure 4, the method for the present embodiment includes:
S41, mainboard electrifying startup PMON to be measured to order line.
If PHY chip is with CRC (Cyclic Redundancy Check, cyclic redundancy check) error count function
Chip, such as the 88E1111 chip of Marvell thens follow the steps S42, tested whether crc error；If PHY chip does not have
Crc error tally function then skips step S42, executes step S43.
S42, the mainboard a to be measured and good mainboard b of another piece of network-in-dialing is passed through into the direct-connected RJ45 interface of cable, passed through
The mode of PMON order line configures and enables the crc error tally function of the PHY chip of mainboard a to be measured, in mainboard b to master to be measured
After plate a sends network packet, the crc error counter register of PHY chip is read by way of PMON order line, according to
It reads result and carries out respective handling.
If being connected with router, interchanger among mainboard, the network packet of crc error can be by router, friendship
It is dropped when changing planes, the PHY chip of network interface card can not just receive these data packets, and it is even more impossible to detect whether data packet has CRC
Mistake, it is therefore desirable to carry out mainboard a to be measured and mainboard b direct-connected.
Test program 1 is executed under PMON order line: being configured and the crc error of the PHY chip of enabled 88E1111 counts function
Energy.
Mainboard b sends network packet to mainboard a to be measured, executes test program 2 under PMON order line: reading 88E1111
PHY chip crc error counter register, if read value be 0, continue to execute step S43；If the value read is not 0,
Then show that the network-in-dialing of mainboard a to be measured is abnormal.
S43, by the network interface card of mainboard to be measured and PHY chip 1000M full duplex mould is configured by way of PMON order line
Network packet is sent to PHY chip by network interface card by way of PMON order line by formula, and the PCS of PHY chip will be described
Network packet sends back to network interface card, and the data that PHY chip is sent to by network interface card and network interface card are compared from the received data of PCS,
Respective handling is carried out according to comparing result.
Specifically, by configuring the PHY chip of mainboard a to be measured, so that the network interface card of mainboard a to be measured is issued network packet and arrive
PHY chip sends back to network interface card in the PCS of PHY chip, as shown in Figure 5 again.
Test program 3 is executed under PMON order line: network interface card and PHY chip are each configured to 1000M full-duplex mode, is configured
And the interior loop back mode of enabled PHY chip, the filling initialization network card data area data to be sent, and these data are sent, it passes through
Interior winding, network interface card receive these data, the data that network interface card is sent are compared with the data received, if the two one
It causes, then shows that network interface card is normal to the data path of PHY chip, continue to execute step S44；If the two is inconsistent, show that network interface card arrives
There are problem, tests to terminate for the data path of PHY chip.
S44, network packet is sent to RJ45 interface by network interface card by way of PMON order line, and in RJ45 interface
The network packet is sent back into network interface card, by be sent to by network interface card RJ45 interface data and network interface card by RJ45 interface number
According to comparing, the network connectivty of mainboard to be measured is determined according to comparing result.
Firstly, RJ45 interface is connected cable, the reception data line for sending data line docking cable of cable.That is: by net
4 internal transmission lines and 4 piece-root grafting take-ups are linked to be 4 pairs, then this cable head is inserted into RJ45 interface by one cutting of line
On.The network packet that network interface card issues sends back to network interface card in RJ45 interface again, on the basis of step S43 passes through, tests PHY
Whether the data path of chip to RJ45 interface is normal, as shown in Figure 6.
Test program 4 is executed under PMON order line: network interface card and PHY chip are each configured to 1000M full-duplex mode, is filled
The network card data area data to be sent are initialized, and send these data, through outer winding, network interface card receives these data, by net
The data blocking the data that send and receiving compare, if the two is consistent, show PHY chip to RJ45 interface number
Normal according to access, the network-in-dialing of the mainboard is good；If the two is inconsistent, show PHY chip to RJ45 interface data path
There are problem, the network-in-dialing of the mainboard is abnormal.
Further, since the semaphore request under different bandwidth mode is different, in order to make final test result more
Reliably, step S43 and step S44 can be repeated, during executing step S43 and step S44, by network interface card and PHY
Chip is each configured to 100M full-duplex mode, 10M full-duplex mode.
If the data that step S44 is tested under 1000M full-duplex mode, 100M full-duplex mode and 10M full-duplex mode
Access is normal, shows that the network-in-dialing of the mainboard is good；
If there are problems for the data path that step S44 is tested under 1000M full-duplex mode, and in 100M full-duplex mode
Or the data path tested under 10M full-duplex mode is good, shows although the network-in-dialing of the mainboard has some problems, but still
It is available reluctantly；
If the data that step S44 is tested under 1000M full-duplex mode, 100M full-duplex mode and 10M full-duplex mode
There is problem in access, show that the network-in-dialing of the mainboard is abnormal.
