Nexus 5548 (7.1.0.N1.1a) trunk issue

Hi all,

 

i have a couple of nexus 5548 configured in a VPC topology.

I connected the nexus to a couple of 3750 (stacked).

Port-channel is up but spanning tree shows vlan 1 is blocked (nexus side) due ti a PVID inconsistency.

All the Others vlans are in forwarding

Both 3750 and 5548 has VLAN 1 as native.

I also configured a single link beetwen 3750-1 and nexus 5548-1 with the same issue.

3750 is running PVST nexus R-PVST.

It look like a bug

Did any one of you experience the same issue?

Nexus config in the last test (one link)
