Virtual Connect / 3Com swith VLAN passthrough

Hi All,


I'm currently running two C3000 chassis's both connecting through virtual connect switches, these are both set to allow VLAN tunnelling. Both VC's connect to a 3COM 5500G but are not able to pass any VLAN information. 


Is there a CLI command on the 3COM to enable VLAN tunnelling so both blades can communicate.


I've found this command 'port trunk permit vlan all' , would this be suitable?


Many thanks
