Re: Ether Type and Protocol Type

Hi all

When will u find the ether type as Dot 1Q (0x8100) and Q in Q (0x9100)

Wat s the protocol field in IP header when the payload it carries is also
another IP header ( in case of IP in IP tunnel).

Can anyone send me a link for different values of protocol types ?
