Are you sure the switch is acting correctly? I mean: the switch also has to pad the packets to the correct size. If it removes the vlan tag it *has* to add padding to the packet. Switches, how stable they seem, are known to have bugs. These switch bugs are known to occur: - drop packet since payload without tag is < 64 bytes - After removing tag forget to pad to 64 bytes. The e100 is known to pad (hardwarewise) to the correct minimal payload of 64 bytes. -- begin LOVE-LETTER-FOR-YOU.txt.vbs I am a signature virus.
