=> the circuit-id must be either a quoted-string or in hexadecimal.

=> this is a quoted-string so accepted by the parser.

=> 332F322F312F is 3/2/1/ i.e. there is not the trailing vlan 800.

=> IMHO there is not in packets what you expected. I recommend to check
the real content with another tool (tcpdump, wireshark, tshark, etc)
which can display packets from the wire. If the problem on the relay side
can't be fixed '3/2/1/' should match.
