Conﬁguring Token Ring Packet Translation

The middle section of the Bridge Translation window allows you to select the Ethernet frame format the bridge will use to translate various packet types that have been transported across Token Ring media.

Figure 2-33. Token Ring Packet Translation

The three Token Ring packet types you can conÞgure for translation are:

¥Novell packets

¥IP packets (including ARP packets)

¥AppleTalk ARP packets

You can set each type of packet to either Enet (Ethernet) or SNAP (Token Ring 802.5 with SNAP) packet formats.

To set a selected packet type to Enet or SNAP:

1. Click on the empty Enet or SNAP option button, located to the right of the selected packet type. When the option button is ﬁlled ( ), the selected packet format is enabled.

NOTE

For the Novell Token Ring packet the SNAP format is invalid. When the SNAP format is selected the packet will actually be translated into Novell 802.3 format.

If you are using Appletalk Phase-II, the mode of Appletalk ARP should be set to SNAP.

Conﬁguring Novell Token Ring Packet Translation

The next section of the window allows you to select the bit ordering of the hardware addresses located in the data Þeld of a Novell Token Ring packet. The data Þeld contains all bytes of the packet, with the exception of the MAC header and CRC byte. For more information about bit ordering and translation, see Using the Novell Translation Window, page 2-97.
