Editing IEEE 802.2 (section)

=== IPv4, IPX, and 802.2 LLC ===

Although [[IPv4]] has been assigned an LSAP value of 6 (0x06) and [[Address Resolution Protocol|ARP]] has been assigned an LSAP value of 152 (0x98), IPv4 is almost never directly encapsulated in 802.2 LLC frames without SNAP headers. Instead, the [[Internet standard]] RFC 1042 is usually used for encapsulating IPv4 traffic in 802.2 LLC frames with SNAP headers on [[Fiber Distributed Data Interface|FDDI]] and on [[IEEE 802]] networks other than [[Ethernet]].  Ethernet networks typically use [[Ethernet II]] framing with [[EtherType]] 0x800 for IP and 0x806 for ARP.<ref>{{Citation | title = LKML | date = 2011-07-27 | url = https://lkml.org/lkml/2011/7/27/169}}.</ref>

The [[Internetwork Packet Exchange|IPX]] protocol used by Novell [[NetWare]] networks supports an additional [[Ethernet]] frame type, [[Ethernet frame#Novell raw IEEE 802.3|802.3 raw]], ultimately supporting four frame types on Ethernet (802.3 raw, [[Ethernet frame#IEEE 802.2 LLC|802.2 LLC]], [[Ethernet frame#IEEE 802.2 SNAP|802.2 SNAP]], and [[Ethernet frame#Ethernet II|Ethernet II]]) and two frame types on [[Fiber Distributed Data Interface|FDDI]] and other (non-Ethernet) IEEE 802 networks (802.2 LLC and 802.2 SNAP).

It is possible to use diverse framings on a single network. It is possible to do it even for the same upper layer protocol, but in such a case the nodes using unlike framings cannot directly communicate with each other.
