Nexus 2248 ports for Hyper-V virtual switch uplink
I'm having problems getting VMs sitting on a Hyper-V host to communicate properly. Does anyone know if there are issues with using the ports in on the Nexus 2248 and/or FEX modules in general for this purpose? Since they are seen as a Virtual Switch in the Hyper-V host machine, I'm wondering if it is a limitation of the FEX module.

Re: Nexus 2248 ports for Hyper-V virtual switch uplink
Thanks for the reply. I did end up figuring this out. It was a VLAN turnking issues on the core layer above the 5K and not a Nexus 2K limitation. So far the Nexus 2K switches are working out fine although I think I may be done 2960S switch stacks with the 10GB uplinks from my distribution layer if I had to do it all over again for just 10/100/1000 ports. Obviously the new 2232 models with oversubscribed 10GB ports are unique to this line of devices.
