This is where I have the problem. The switch port is either a trunk, or
a VLAN member. Example:

cat4003> (enable) sho port
Port Name Status Vlan Level Duplex Speed Type
----- ------------------ ---------- ---------- ------ ------ ----- ------------
 2/1 connected trunk normal full 1000 1000BaseSX
 2/2 connected trunk normal full 1000 1000BaseSX
 2/3 notconnect 1 normal full 1000 No GBIC
 2/4 notconnect 1 normal full 1000 No GBIC
 2/5 notconnect 1 normal full 1000 No GBIC
 2/6 connected 1 normal full 1000 1000BaseSX

Do I have to force it into "trunk" mode ?

Thanks,
