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:
