I used an older “dumb” switch and i was able to successfully register a host.
If an older / unmanaged switch solved your issue, then have your network engineers look at your switch configuration. Make sure one of the fast spanning tree protocols are enabled (RSTP, Fast-STP, or what ever your switch mfg calls it). This will allow your switch port to start forwarding data right away instead of waiting for the obligatory 27 second timeout of start spanning tree protocol.
