I have a Huawei S6720 and Juniper EX4500 interconnected through WDM device, the two port of WDM are normal in transceiving light, 2-terminal equipment modules are also normal in transceiving light, the interface is bright, but it will happen interface DOWN, over a period of time the interface UP itself again. There has nothing configuration on the 2-terminal equipment. Why is that happen, is there any command to change the interface attributes to match with Juniper?
