Nexus 5548 with SFP-10G-LR

[Weverton Aranha]

I have 2 Nexus 5548 connected by 2 links using SFP-10G-LR Gbics. All the ports are in protocol down state. I`ve already tested the cabling between the DCs - it is monomode and OK. Does anybody knows if it could be a N5K configuration parameter, software relase or something like that?

Have you tried swapping the positions of the two fibre cores on the fibre fly lead when it is inserted into the two connections on the fibre SPF?

Sean,

I`ve tried all the conection position possibilities.
