On a certain day of a certain month of a certain year, there was a WAF test, and Green League WAF was one of the test subjects.

I still remember that it was a sunny day, with manufacturers, sales and technology gathering together. 2U large WAF is put on the shelf for debugging. After plugging in the module and optical fiber, it was found that the light was off and the link was down. Does the module not work well? Does optical fiber not work well? These have been tested on other switches, no problem! Why doesn't it work?

Restart it! At this time, the hell happened, after the restart can not identify the 10-gigabit interface, can not see the 10-gigabit card!

What happened? Is the card not plugged in properly? Turn off the power, plug and unplug the card, not yet! It's not enough to change slots!

This is the worst thing!

Contact to replace the equipment. It's the only way!

A few days later, the new test equipment was put on the shelves again, and the same thing happened again! Didn't you worship the wharf? Another test still doesn't work! Is it possible that there is something wrong with this equipment?

How about another one?

Another device came, but it fell in the same place! This kind of thing can definitely drive people crazy!

We have no choice but to pull the equipment away! Power up the equipment when you get back to the office, ghost! Unexpectedly found the 10-gigabit interface, identified the 10-gigabit card!

The incident came to an end.

I have seen ghosts again these days, and a new equipment has been put on the shelves, which is the same as before!

Restore the factory, re-initialization have no effect, it is impossible to just leave the factory there is a problem, right? Could it be the module?

I unplugged the module of sangfor and the module of another device in the computer room and tested it on WAF, and it didn't work! It's not like a module problem, is it?

I had a phone call with BOSS, and he said that I would like to try other modules of the company.

Take the company's three sets of modules to the scene, plug them into the equipment and turn them on, huh? Unexpectedly found a 10-gigabit interface, the card identified! Try another set of modules, huh? It's recognized again! Three sets of modules have been tried, no problem at all, how to restart WAF can identify the 10 Gigabit board card.

Try to connect the original module again!

He he! Sure enough, I can't see the card again after reboot! This is a ghost!

At this point, the ghost was finally found out! It's the problem with the module!

But I still don't understand why the module problem causes WAF not to recognize the 10 Gigabit card!
