Hello,
We have a N7706 (module N77-F348XP-23) and FEX N2248TF-E
This link says that N2248TF-E is a N2248TP-E
https://www.router-switch.com/pdf/n2k-c2248tf-e-datasheet.pdf
This link says that N2248TP-E does not support FCoE
This link says that N77-F348XP-23 supports FCoE
So, at the end, Will Nexus 7706(F3) combined with Nexus FEX 2248TF-E support FCoE?
Look at the below guide for the correct model support FCoE
if you like to use parent switch as FCoE, you ignore FEX models and deploy directly on Parent switch to save resource,.
maybe your case may be different.
parent switch support.
