[c-nsp] nx3k fresh install - ports not forwarding

[Randy]

Hi,
On your TORs - is your STP config identical for all applicable-VLANs? (vlans have to be in STP) since IIRC, Bridge-Assurance and STP port-type *network* is enabled by default on the VPC peer-link; in this case on vpc peer-link between TORs

Yes domain ids are unique.

Are your VPC domains unique?  It seems like I had something like this and it came down to an issue with conflicting VPC domains.
