Solved: Question regarding FEx and N7K

udid · ‎02-14-2013

Hello guys,

Does anybody know if I can connect FEx to multiple VDCs?

Thanks!

Hi,

All the uplinks and host ports of a Fabric Extender belong to a single VDC. The ports cannot be allocated or split among multiple VDCs.

Have a look at the config guide below:

Hi,

No, the VDCs can't see each other unless you physical connect the 2 VDCs together. So, you can't form a Portchannel.

Hi,

I'm aware of the fact that VDCs can't see each other.

I only ask if FEx can be connected to two VDCs.

Can two VDCs be a home for a single FEx?

Hi Reza,

Thanks for the clarification!

Have a nice week.

A single FEX can only belong to a single VDC. This means that all your uplink fabric ports on the 7k must be in the same VDC. UNLESS you have created a vpc between 2 separate VDCs and you portchannel to the FEX.
