You got a bad fibre line.  The value I've highlighted should always be "255" and nothing less.

Hello,

thanks for all,

the issue was solved, by using an other type of SFP on the huawei side

Simple Layer 1 issue. :-)

Hey Inayath,

Have you seen a link type like this?  "force-up"?  I don't remember seeing this.

[InayathUlla Sharieff]

Leo,

I didnt see it or might not have noticed it.

Anyhow this is the explanation for it:

If either device does not support gigabit auto-negotiation , disabling gig auto-negotiation will force the link up henc eyou see that. (AS you know the switch default to link type Auto).

[tarik sayel]

Hello,

Yes, you are right InayathUlla about "force-up" .

[InayathUlla Sharieff]

I am right but no rating for me :-) just joking.

Have a nice day we are happy your issue has been resolved.

[Leo Laohoo]

Rated, Inayath. 

[InayathUlla Sharieff]

Yeah thanks dear leo.
