Boris,

This sounds normal - your vlan probably has a max MTU of 1464 bytes (one =
of the ethernet standards uses this instead of 1500 I think). If you =
want to transmit larger frames, you have to up the MTU on your adapter =
and on the switch somehow. I think this is referred to as 'jumbo =
frames.'

If you set the adapter MTU to 1464 you should not have problems sending =
and receiving, your packets will just get fragmented.
