"Belief" isn't really sufficient.  You need to verify it.

The fact that you have NATIVE and DEFAULT vlan ids the same worries me.
(If I had my way, CP would reject that as a configuration error.)

Since you are using a virtual trunk port, did you configure the guest to
be VLAN aware (vconfig, etc.)?  All of those errors are probably due to
mis-tagged frames.  (If the guest only needs access to a single VLAN on a
VSWITCH, leave it as a virtual ACCESS port.)

That said, if you DID enable the guest to use VLAN 32, CP will say "It's
the same as the native VLAN" and will, IIRC, REMOVE the tag.  If the port
default VLAN id is NOT actually VLAN 32, then the data will drift off into
Never-Never Land.

The other likely problem is that the physical port is actually in ACCESS
mode, not TRUNK, with its default port VLAN id set to 32.
