GS724Tv4 AVB/MSRP Issue

Hello all,

We've purchased a GS716T and GS724T for our internal AVB network, and are running into a bit of a problem. We're starting off with a simple test with one talker and one listener on our network, but when we engage the listener its port is showing MSRP Error 17 "VLAN is blocked on this egress port (Registration Forbidden)". The talker stream is using a VLAN ID of 2, and I believe I have all the AVB blocks configured correctly.

What could be going on here?
