Wireshark-users: Re: [Wireshark-users] Why redundant frames?

Hi All,

More info. Each frame in wireshark is listed as having 539bytes captured and on the wire. My MTU is set to 1500 byte packets so if this is a fragmentation of data why would the data be split into two frames when one should have at least used two packets within a frame?

Sorry for the questions I am a newbe to this level of analysis.

Many Thanks,
-Tony
