Default FDDI Translations
The fddidef command allows you to set up default translations for all FDDI ports. To do this:
1. Enter the fddidef command at the system prompt. The following screen displays:
This will reset the default translations for FDDI media to a new value.
All FDDI 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 FDDI 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 translate incoming IPX Ethernet 802.3 frames to Ethernet
802.3 frames (FDDI raw), then you would enter
4=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.
