3.5.2.3Bridge 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:
