Strange one really, and a little embarassing at the same time...
- Two N5K's with 4 x 10G connections to VSS
- Using OM3 multimode
- 2 meters distance
- X2-10GBASE-SR tranceivers on the 6509's
- Basic port configurations
- Swapped out tranceivers
- Checked fibre pairs are around the right way
- N5K's are connected to one another
The interfaces will not come up!
It's not like i'm new to all this kind of thing, but im seriously stumped as to why I cant get any joy.
