Default Ethernet Translations

The ethdef allows you to set up default translations for all Ethernet ports. To do so:
1. Enter ethdef at the system prompt. The following screen displays:
This will reset the default translations for Ethernet media to a new value.
All Ethernet ports currently set to default will inherit these new translation options.
It will thenreset the forwarding table translation options for all addresses learnt on
those ports to those port defaults.
Do you want to do this? (no):
2. Press Y at the Do you wish to do this? prompt to indicate that you want to change the
defaults. The current settings for Ethernet ports are displayed, in a screen similar to the
following:
Translation Options:
1 IP Ethertype -> Ethertype
2 IP IEEE 802 SNAP -> Ethertype
3 IPX ETHERNET_II -> 802.3
4 IPX ETHERNET_802.3 -> 802.3
5 IPX ETHERNET_802.3/FDDI/TOKEN_RING -> 802.3
6 IPX ETHERNET_SNAP/FDDI_SNAP/TOKEN-RING_SNAP -> 802.3
There are six frame types for which you can set translation options. The frame type in the
left column indicates the incoming frame, and the frame type in the right column (after
the ->) indicates the outgoing frame. You can configure the outgoing frame type for each
incoming frame.
3. You change an outgoing frame type by entering its line number, an equal sign (=) and a
frame type indicator (e, s, 2, or 3). The frame type indicators represent the following
frames:
e Ethernet II or Ethertype
s SNAP
2 802.2 or LLC
3 Ethernet 802.3
For example, if you wanted to change incoming IPX Ethernet II frames to Ethernet 802.3
frames, then you would enter
3=3
Please note that the IP Translation Options accept only Ethertype (e) or SNAP (s).
4. When you are done changing translations, enter save to save all of your settings. If you
enter quit, you will exit the ethdef command without saving your changes.
