Issue Description

A project added 12 sets of sig1000, all of which have already been configured management address through the serial port, but in the web platform, when adding equipment, there is always a sig1000 adding failure. At this time the equipment cannot ping pass and be unable to log in.
Delete all the configurations, all the 12 sets of equipments can ping pass and can log in.

Alarm Information

Add the failed sig1000, failure alarm information is only adding failure, not prompts address conflict.
After added 11sets of sig1000, there is a sig1000 has the address conflict alarm.
After delete all, there is no address conflict alarm.

Handling Process

1, Use serial ports log in each sig1000, through the “bootchange” querying, all addresses are configured correctly.
2, web configuration error, due to the web server its own mechanism has controlled that when configuring in web page, it could not add successfully if configured the same two addresses, so this reason is ruled out.
3, ping can't add sig1000’s management address, find the reply message is:
SIG-SRS:~ # ping
PING ( 56(84) bytes of data.
From icmp_seq=6 Destination Host Unreachable
The initial judgment is the configuration of the third sig1000 is error. Find the third sig1000 information added 10 sets of sig1000’s id number.
4, Login the third table sig1000, use “bootchange” command querying, found that the equipment actually is the 10th table sig1000
5, delete the third table sig1000 and add it again, can add the 10th sig successfully without warning.

Root Cause

1, the configuration errors, when using the serial interface configure sig1000, equipped with two addresses which are the same.
2, web configuration errors, when configuring in the web page, equipped with two addresses which are the same.


Web configuration mechanism realized through the SRS, after the field engineer configured the management address of sig1000, sig1000 communicates SRS successfully, namely will send the equipment information (including management address, id number etc.) to SRS. In web configuration, SRS through querying the id number, can modify the corresponding sig1000’s management address, but it only modifies the network interface’s address and not modifies the information of the boot, thus caused when adding the third sig, though the id number is wrong, it can also be added successfully. When ping the 10th sig, the reply information is: From icmp_seq=6 Destination Host Unreachable
