[Mike Hammett]

Transport provider admitted to having a VLAN filter in place. They're working to fix that.

Subject: [c-nsp] Nexus Config Sanity Check 

We have a Nexus 3548 connected to Ethernet transport connected to a Mikrotik CCR on the far end. The CCR's configuration is fairly straight forward, but so is the Nexus. We have a native VLAN (200) and a tagged VLAN (778). We're not seeing each other over 778. 

Thoughts?
