Alarm Information


Handling Process

1.Ask customer provided the information, including license file (*.DAT), output of commands display license and display ESN.

2.After checked the license file in use , it was found that there was only one ESN (210xxxxxxxxxxx000012) of the CSS system in the license file.
<SwitchB-CSS>display esn
ESN of slot 1/7: 210xxxxxxxxxxx000013
ESN of slot 1/8: 210xxxxxxxxxxx000013

3.Confirmed with R&D, if worked in 1+1 CSS system, the two license of each S9700 needed to be combined.
4.Send email tolicense@huawei.comand ask engineer to combine the two license, the issue was resolved.

Root Cause

The license file in use was "s9700_xxx.dat", after checked the license file, we found only one ESN of 210xxxxxxxxxxx000012 was related in it. However, in 1+1 CSS system, there are two ESN, 210xxxxxxxxxxx000012 and 210xxxxxxxxxxx000013. So it was because the license file wasn't right that made the status abnormal.


1.For license issue, you can send email to license center with email address
2.For the design of the license thing in CSS system, RM is submitted to make it better. The idea is that each s9700 has its license as working alone, if you want to use 2 or 3 or more to work in CSS system, just connect them via cable, no need to apply for license again.
