Re: PVLAN on 3750

Hmmm, sounds very strange, as the configuration is pretty straight forward
as you have mentioned.

One quick test to verify this: how about if you created an SVI for the
primary VLAN and added the mapping on there. Does the problem persist?

I understand this might conflict with your network design but this is
strictly for troubleshooting sake.
