2(ethernet2) Ethernet2 frames are the same as 802.3 frames, except
they use the third field (the length field in 802.3) to store
a value representing the type of transport packet that is
encapsulated within the Ethernet packet.
3(ieee802.2) 802.2 is the default for non-Ethernet links. 802.2 frames
are the same as 802.3 frames, except they have Logical
Link Control (LLC) information encoded within them
immediately following the 802.3 length field.
4(snap) SNAP frame types use the SNAP encapsulation method
within 802.3 or Ethernet2 frames. This frame type
contains higher level protocol information. This frame is
the same as 802.3 frames up to length field. The length
field is followed by SNAP information which contains
protocol information and an “ethertype” field.
IP Routing
IP is the TCP/IP protocol that specifies how information is to be broken into
separate packets, and how those packets are to be addressed in order to be routed
over a TCP/IP network.
You may enable any port in your ATX Chassis for IP routing. To access the IP
Routing window:
1. Click on the appropriate Port button. A menu will appear.
2. Drag down to IP Config/Routing and release. The IP Config/Routing window,
Figure 2-9 , will be displayed.
