We have a new AT&T ASE point to point (layer 2 metro ethernet) circuit with a 1GB port. At one location, we have a N3024 and a 6248 at the other end. The circuit is terminated with multi-mode fiber - SC connector. On the N3024, it connects with a link light. On the 6248, we cannot get a link light using the SFP+ port on the front. We also installed the a 10GE SFP+ module in bay 2 of the 6248. I configured the 10G using a similar commands below. I am unable to get a link light and I've tried setting port speeds, different transceivers (diagnostics show good). When I connect an old 5424 to the same circuit, I get a link light.
In summary, I have 2 basic questions:
1) Has anyone ever connected Dell switches to AT&T ASE service? Please pass on tips/tricks. I've done it on Juniper with no problem.
2) Can I connect the 6248 to a N3024 using the 10G SFP+ port on the 6248 across the metro ethernet?
3) Am I missing anything on why I can't get a link light on the 6248?
