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. -Will
