We have a pair of Nexus 5596 switches, that each have a 1 gigabit conection to ISP CE switches (ME3400).
Switch 1 has a fibre connection using GLC-SX-MM with the following information...
sh int e1/48 trans
Ethernet1/48
transceiver is present
type is SFP-1000BASE-SX
name is CISCO-AVAGO
part number is SFBR-5766PZ-CS2
revision is
serial number is AGA1549L2BE
nominal bitrate is 1300 MBit/sec
cisco id is --
cisco extended id number is 4
I cannot get the port to come up on switch 2, transceiver info...

I have tested the SFP's in use on a pair of 2960's & they work fine!
If i replace the SFP's for copper, then they work fine also.
Does anyone know of any incompatibility issue with this SFP?
Thanks

Make sure you have set the speed to 1000 ( speed 1000) on the interface and that you have at least 5.0.3 version or later of NX-OS

Did you try removing "duplex full" command and use "duplex auto"? nexus 5500 never autonegotiate to half duplex in anycase.
06-07-2012 10:07 AM
yes tried that.
then removed all config from the interface & re added line by line

Did you try a different port such as e1/1? Sounds like a bug to me

We had limited time during the change window.
That is the next step & to also swap with a known working SFP!

We had same issue recently:
Our ME3400-12 (uni port)
connected to non-Cisco device.
Our port was up (SFP GLC-LH-SM), their port was down.
It was bad SFP on our end, I will RMA it.
In your case it looks like ISP issue - I don't know how much power you have to push them to replace SFP.

This issuw was a problem with the swich.
Once an RMA was performed & switch replaced then isse was solved
