Issue Description
7500 ASON network,the version is R9C04SPC011;7500 need to connect with the huawei router in the DLAG protection,in the U2000V1R1,we  configure the DLAG protection, in the different N4EGS4 board(7 slot and 15 slot) of the 7500 ASON NE,the U2000 clue on fail.

Alarm Information
creat new  DLAG protection,,clue on fail,error code is 40027(invalid BLSR protection group ID).

Handling Process
1、we configure the DLAG in the T2000,we found the same probelm,so it is not U2000 problem.

2、we try to configure the DLAG in the N4EGS4 of the different 7500 NE;we can configure the DLAG,if there are no ASON services in the EGS4 of the 7500 NE,but another 7500 NE,we can not  configure the DLAG,because there are the ASON services.

3、refer to the R&D,the R&d find that there is restriction in the SCC software,so when we configure the DLAG in the N4EGS4 board,we should confirm that there are no ASON services in the N4EGS4,it is the same problem with the R5 ASON plat,need upgrade the NE to V100R010C03SPC100( to slove the problem.

3、temporary solvetion:we downgrade the ASON services to general services,and then creat the DLAG,after that,we need to upgrade the generalservices to ASON services again.

1、U2000 probelm.

2、EGS4 board probelm.
