U2980 version is V100R001C01SPC106,we use CDE OMU Client connect to OMU board,OK. when we use command SET OMUOMIP to set ip 10.255.3.36 under CDE net element, but it says ip is The illegal.
after contact RD, we get the method:
1、use root user log into OMU board.
3、in the sub validate_ip_address function，find this script：if($ipaddr[$i] eq "" || $ipaddr[$i] < 0 || $ipaddr[$i] >= 255),
revise $ipaddr[$i] >= 255 to $ipaddr[$i] > 255
4、save and quit, reboot OMU.
5.try to use command SET OMUOMIP to set ip 10.255.3.36 under CDE net element, now it is ok.
we try to config another ip 10.10.10.8 for OMU ip,display success,then I reboot the OMU board, test the new ip, we can log into OMU board through new ip. the same way we try to config another ip 192.168.100.22, also test is ok. but when we try to config 10.255.3.36 for OMU still display ip is illegal. I think need to revise some file in the OMU board.
