MTU commands flavors
Hello all, i would like your help in understanding the differenet types of MTUs in IOS CLI. I have searched a lot but found nowhere a straight answer.
This is the mtu for the physical interface,correct? Does this mean that all L2 overhead is excluded? E.g for non-tagged ethernet we have 14 bytes for header + 24 bytes for others = 38 bytes/packet total overhead. So is this value maximum 1500, having as a result 1538 bytes totally transmitted?
Does this include IP header (20 bytes)?
I dont know what this includes
Any help is very welcome!
