Please log in for more thread options As I understand it, there is some possibility that full length packets, which are four bytes longer than the standard, will be discarded. I haven't heard that any do that, though. > How L2Bridge will act if its receives VLAN tagged packets.
Pass them through in the same way as any other packet. -- glen | |||||||||||||||||||||||||

How it will work if the end station is a host not an L2Bridge device.

You have to consider VLAN as part of the network design, and not connect VLAN unaware devices to ports with VLAN tags on them destined for that device. Though these days, there is likely VLAN software for most operating systems. -- glen | |||||||||||||||||||||||||
