Why Does an NE40E Fail to Be Interconnected with a Huawei Switch Through Optical interfaces Although the Rx/Tx Optical Power of Optical Modules Is Normal

Publication Date:  2019-04-16 Views:  30 Downloads:  0
Issue Description

Why does an NE40E fail to be interconnected with a Huawei switch through optical interfaces although the Rx/Tx optical power of optical modules is normal?

Handling Process

The Rx/Tx optical power of the optical modules on interfaces at both ends is normal, but the negotiation modes at both ends are different. According to the product document, it is learned that:

The auto-negotiation function of optical interfaces on an NE40E is disabled by default.

The auto-negotiation function of optical interfaces on a Huawei switch is enabled by default.

To address the problem, change the negotiation modes at both ends to be consistent.
