Novell's Name

Cisco IOS's Name

Hints for Remembering the Names and
Meanings

Ethernet_II

ARPA

One way to help correlate the two names is to
remember that ARPA was the original agency that
created TCP/IP and that Ethernet_II is the older
version of Ethernet; remember that the "old" names
go together.

Ethernet_802.3

Novell-ether

Novell's name refers to the final header before the
IPX header, in this case. There are no suggestions
on easier ways to recall the IOS name Novell-ether.
This setting is Novell's default on NetWare 3.11
and prior releases.

Ethernet_802.2

SAP

Novell's name refers to the final header before the
IPX header, in this case. Novell's name refers to the
committee and complete header that defines the
SAP field; Cisco's name refers to the SAP part of
the 802.2 header. (The SAP field denotes that an
IPX packet follows the 802.2 header.) This setting
is Novell's default on NetWare 3.12 and later
releases.

Ethernet_SNAP

SNAP

Novell's name refers to the final header before the
IPX header, in this case. Cisco's name refers to this
same header.
