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.
