Dear Members List,
I've just started the track for CCNA and, following all the repeated advices
posted in this list, I started studing for Internetworking with TCP/IP, by
Douglas Comer.
The ethernet frame format stablishes as necessary information for the frame
as DA, SA, Type, Data Area(variable from 46 to 1500 bytes) and a trailer FCS
4 bytes.
I don't see how can we have different frame sizes correctly received, since
there is no information about the specific lenght for every single frame,
taking in account the asynchrounous nature of this communication.
I thought that the layer 3 would pad till the MTU was reached, but I saw a
trace on an ethernet network and I could see different frame sizes.
Thanks in advance,
Douglas Baltazar de Queiroz - Field Enginner
