Errrr.... According to the interfaces status and the routing table, this is the
case, or do I misunderstand your question ?

No, there is no "trunk" ports. The term trunk is used by Nortel for MLT. And,
precisely, that what's "show mac-address-table" displays : the MLT table. The
port I'm connected to is simply a port shared by all Vlans.

Thanks for helping
