I have few questions about Snap header in the 802.3 ethernet.
My book says" another popular option exits for the protocol type field,particularly when sending ip packets. If the 802.3 type/length has a value less than 1536,the type/length field is used as length field for tthat frame,identifying the length of entire frame. In that case another field is needed to identify the type L3pdu inside the frame. " Snap header is inserted the frame to identify the L3pdu.
My question is how common is it to find ethernet with snap header carrying ip packets? Most of the ip packet i captured using wire shark, use the 802.3 ethernet where type field is used to indicate the encapsulated ip packet. Is it common for ip packets to use ethernet framing weith simply" type" field?
