During change time after connecting Huawei core devices (HLR and STP) ,GE electrical links configured on NE40E did not become up.
1.First we checked the physical connections,we checked RJ-45 connectors,then because of large sacle of cabling we did check that correct cables connected to correct ports or not,also we did check connections to patch panels .all the cabling was ok.
2.we checked the configuration on port,it was ok.
3.we checked configuration on HLR port,it was ok.
4.The port was also undo shutdown.
5.Just we did shut down and again undo shutdown those ports and they became up.
1.Check physical connections.
2.Check the configuration on both side.
My suggestion is,because we usually make the configuration in advance,and during the change time just we do copy and paste,it is better to do shutdown and undo shutdown on connected ports,if they are not active.
