no link up from Cisco switch with single mode transceiver....

Hi Experts,

I have to create a new link from my fibre box to my switch.
This is single mode and the cable is an LC-E2000 cable.

I am not able to bring the link up.

I am using the switch C2960X with Singlemode transceiver. But this is not the original transceiver it is a cheaper one.
But in the config the transceiver is visible.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If it is not original it may not work properly (but output above look pretty good).

Did you try to swap one side of fiber (maybe RX RT strains are not matching)?
Are SFPs on both link sides compatible?

Hi,

yes I have tried and swap over the cables on one side. This is not the problem.

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Eprs_AdminSystem ArchitectAuthor Commented:
ok do you mean set speed and duplex especially for this interface ?
0
JustInCaseCommented:
There is no speed and duplex settings on 10G SFP interfaces (and for any newer 1Gb interfaces too).

atlas_shudderedSr. Network EngineerCommented:
Not so Pre - I have to run this command regularly still in my 9Ks.

Eprs - Can you please post the following info from the switch

show ver
show run int Te1/0/2
show int Te1/0/2
show ip int br | inc shut
show int status | inc err
show run int gig 1/0/50
show int gig 1/0/50

The last two may not return output but if they do, the output will be helpful

Thanks

JustInCaseCommented:
Those commands are for SFP+ fiber ports. Ports support 10G and 1G depending on SFP that is inserted, but configuring duplex and speed is not present.
The only command that I issued (rarely) for speed in last 2-3 years on is

Interface <typee><number>
 speed nonegotiate

No other speed and duplex commands are present if fiber SFP is inserted in interface.

Okay Predrag.  Thanks for the input.

Eprs -

If you wouldn't mind sharing the output requested above, I'll try to help.

Cheers

Dirk KotteSECommented:
comes your fibre box (or devices behind them) with 10G?
do you try to connect 1G with 10G?
I think this don't work. Possible this is the problem.

sure the ports at the fibre box are ok?

Eprs -

Are you able to share the information requested above?

Craig BeckCommented:
When you say you swapped the cables at one side do you mean exactly that, or did you flip over the two ends of the connector, so that A and B are the other way round?

on this port I cannot set DUPLEX or SPEED

I just can set SPEED NONEGOTIATE

JustInCaseCommented:
Try to configure speed nonegotiate on both sides, sometimes it can resolve issue (bring connection up).

Issue no shut on gig 1/0/50

I cannot set NONEGOTIATE on both sides. The other side is the provider.

I have set the interface 1/0/50 to no shut.

Nothing changed :-(

...and I have checked and crossed the cables again...

Can you bounce Te1/0/2 now that gig 1/0/50 is turned up?  The interfaces are the same slot.  I've seen in the past where both have had to be turned up to establish active link.

What is the media length involved?

Eprs_AdminSystem ArchitectAuthor Commented:
the cable is just 2m long

But tomorrow the provider is coming by...

I'm tapped Eprs.  Any way to swap the SFP or to test it against a controlled far end?  Another switch, etc.?

That means the cheap SFP+ works fine.
