3.5.2.3 Bridge Number
The ATX, unlike some multiport source routing bridges, does not impute
an internal pseudo-ring, and so its bridge number must be unique on each
of the segments to which it is attached. The omission of the pseudo-ring
has the advantage of increasing the allowable network diameter by
consuming one hop per transit instead of two.
Bridge numbers range from 1 to 15 and must be unique between any pair
of segments. To set the bridge number from LCM for either source
routing or source routing transparent, use the
srbridge command
followed by its value. For example, to set the bridge number to 7, enter:
ATX> srbridge 7
3.6 TRANSLATION OPTIONS
The ATX offers unique abilities to bridge between Ethernet and Token
Ring (as well as FDDI), despite protocol differences between the
dissimilar media. The ATX provides a number of options for overcoming
translating problems. The options are specific to the higher-layer protocol
family.
You can set the types of translations that are available for Token Ring
ports. Ports may have a combination of different translation types. The
translation options are:
• ARP - translates incoming and/or outgoing ARP packets
• srArp - translates incoming ARP packets that are source routing
explorer frames
• IPX - translates incoming and outgoing Novell IPX packets
• APPLE - translates incoming and outgoing AppleTalk ELAP, TLAP,
and AARP packets
The types of custom mixed LAN translations that are available, as well as
the translations that have been activated for your Token Ring ports, can be
displayed. (Currently, custom mixed LAN translations may only be
specified for Token Ring ports.) To display this information enter:
