Hi,
We have two Force10 MXL switches in our blade centre and wanted some expansion for additional storage so purchased two N4032F switches and dual port QSFP+ modules for both ends and 40Gb QSFP cables.
We already have a LAG configured between the two Force10 MXLs and also using two 10Gb LR transceivers to two N4032F switches on a separate site, so assumed it would be relatively easy to add the two extra switches on the QSFP ports.
The new switches have identical configurations except for the port channel numbers as they are simple layer 2 iSCSI switches.
I have been unable to get the 40Gb interface to come up let alone the port channel.
Both sides see the transceivers (40GBASE-CR4-3M) you can connect the two N4032F with the same cables and ports and instant connection, the same with the Force10 MXL, just not to each other?
I assume I am doing something silly but I can't see it.

I'm in the process of switching one of the 40Gb ports to 4x10Gb and trying that as I have the cables spare, failing that try and find a spare 10gb SPF cable.
I am also planning to upgrade all the firmware just in case.
Any advice would be gratefully received,
Thanks,
Ged
