They're Novell-proprietary. I understand your point, but, actually only Novell raw is proprietary. The other options for Novell encapsulation are all standard. ETHERNET_II, aka arpa, Ethernet V.2 and Ethernet II, is standard. ETHERNET_802.2, aka sap, and 802.3 with 802.2, is standard. ETHERNET_SNAP, aka snap, and 802.3 with 802.2 and SNAP, is standard. >To illustrate this point, if you set the IPX encapsulation type to be >novell-ether and you typed "show ipx interface ethernet 0", you'll see >"novell-ether" on the Ethernet 0 interface. However, if you type "show >interface ethernet 0", you'll see that the encapsulation is ARPA which is >different than the IPX encapsulation on that same interface. I would say that's a bug (limitation) with show int. IP uses ARPA, which is Cisco's ridiculous term for Ethernet II. Other encapsulations are used for other protocols. The show int probably just shouldn't show the encapsulation if it's not going to be more specific.
