[RK_2014_0924]Ethernet II VS 802.3一、Ethernet Frame Types: PRovan's Definitive Answer

Novell Frame Type Designation:Ethernet_IICommon name:EthernetLayout:

6 bytes 6 bytes 2 bytes Up to 1500 bytes+-------------+-------------+-------------+-------------------------+| Destination | Source | E-type | Network Protocol Packet || MAC Address | MAC Address | (ipX: 8137) | |+-------------+-------------+-------------+-------------------------+

Comments:

Used for TCP/IP as well as many other protocols.Most common frame type in general, although Ethernet_802.3 might possibly carry more packets world wide.Novell Frame Type Designation:Ethernet_802.3Common name:"Raw" 802.3Layout:

6 bytes 6 bytes 2 bytes Up to 1500 bytes+-------------+-------------+--------------+------------------------+| Destination | Source | Total packet | IPX Packet || MAC Address | MAC Address | length | first two bytes: FF,FF |+-------------+-------------+--------------+------------------------+

Comments:

No protocol ID: Can only carry IPX packets.Distinguishable from Ethernet_802.2 only because the first two bytes of all IPX packets carried on Ethernet_802.3 must be all ones, which makes no sense in Ethernet_802.2.The default frame type for NetWare software until NetWare v4.0 was released.

二、Some examples of values in the type/length field:

0 - 1500 length field (IEEE 802.3 and/or 802.2)0x0800 IP(v4), Internet Protocol version 40x0806 ARP, Address Resolution Protocol0x8137 IPX, Internet Packet eXchange (Novell)0x86dd IPv6, Internet Protocol version 6
