    Just to clarify you need the probe port to be in the same VLAN and Tagged?

    Also I do not have any VLAN routing setup (any layer 3), I wouldn’t think this is required.

      No need for VLAN routing on port mirroring. I inquired your case and they suggested to open a ticket on NETGEAR support so that we can further investigate what is the cause of this issue.
