Oh wow, that's exceptionally retarded. Can you complain to 3COM tech support?

Section 3.31 of RFC3580 lists the tunnel attributes as:

  Tunnel-Type=VLAN (13)
   Tunnel-Medium-Type=802
   Tunnel-Private-Group-ID=VLANID

The RFC author(s) obviously made a mistake, it should have been

  Tunnel-Type=VLAN (13)
   Tunnel-Medium-Type=802 (6)
   Tunnel-Private-Group-ID=VLANID

Absolutely no RFC lists 802 (integer) as a valid value for Tunnel-Medium-Type... It's an enumerated integer attribute *sigh*.

It seems that this has been discussed before however....

... so no point in ranting about it again

Though the if statement should probably be

if(3Com-Product-ID == '4200G'){
