Problem Description

A Gigabit electrical Ethernet single board N2EGT2 has been developed on top of NGSDH V1R9, which supports two types of interfaces: Gigabit optical interface and Gigabit electrical interface. From the appearance, both optical and electrical interfaces are pluggable SFP modules and are of the same size. Recently, many customers have asked whether the optical/electrical interfaces on the N2EGT2 board are interchangeable. That is, whether it is possible to turn the original optical/electrical interface single board into an electrical/optical interface single board by replacing the optical module.

Warning message

None

Processing

1. The first line tries to directly swap the two interfaces, and finds that the service is not available after the swap;

2、After consulting the R&D, it is confirmed that the two interfaces can be interchanged, but after interchanging the optical/electrical interfaces, it is necessary to set the port attributes through the following command line:

:cfg-replace-port:slot-ID,port-ID,sdh-eport/sdh-opport,ge

for the para3, sdh-eport means the electrical interface module ; sdh-opport means the optical interface module ;

Root cause

At present, there is no description of this in the manual and various materials, and the N2EGT2 single board is also the first time to use the SFP optical interface single board at the same time, the first line and the customer has more questions.

Recommendations and Summary

None
