Translation Options
Token Ring Switch Module User Guide Page 3-7
• Oneto6swap – incoming type 6 ARP packets will be converted to type
1 and outgoing type 1 to type 6, with embedded addresses bit swapped.
3.6.2 Source Routing ARP Translation
The Source Routing ARP translation options specify when bridging IP
ARP packets that are source routing explorer frames, whether the routing
information is to be stripped or propagated. The possibilities for option
are the following:
• Off – no special ARP translation is to be performed.
• PassRif – the packet is bridged as is, with route discovery proceeding
as expected (the passRif option is identical to the off option).
• StripRif – the routing information field is stripped before being
propagated (this option allows non source routing (e.g., Ethernet) IP
hosts to communicate transparently).
• PassBoth – both the original source routed packet and its transparent
equivalent are propagated (this option provides maximum
connectivity at some expense in network traffic).
3.6.3 IPX Translation
The IPX translation options specify, when bridging Novell IPX packets,
whether the packets are to be translated to Ethernet-like format. The
possibilities for option are:
• Off – no special IPX translation is to be performed
• On – the default IPX translation of the switch is to be performed (If no
ports have any IPX options, then the default option is ethernet8023.)
• Ethernet8023 – the 802.3 header is to be used without an 802.2 frame
(this also changes the default to Ethernet 8023 framing)
• Ethernet2 – Ethernet 2 framing is to be used, with ether Type 8137
(this changes the default to Ethernet2 framing)
• Ethernet8022 – the LLC header e0, e0, 03 is to be used in conjunction
with the 802.3 header (this also changes the default to ethernet8022
framing)
