5 - 6 Ethernet or Token Ring Bridge

The Token Ring number and the radio ring numbers should be assigned

by your network administrator since each ring in your infrastructure

must be assigned a unique number.

Once these have been determined, all units must be conﬁgured with the

number of the Token Ring to which they are attached. The root unit must

also be conﬁgured with the virtual radio ring number. It will inform the

repeater units of the radio ring number when they associate to the root.

The root unit is also responsible for automatically assigning Bridge

numbers to itself and each repeater unit.

Using the Token Ring Extended Menu

Setting the Size of a Bridge Number (Partition) Token Ring Only

This option only appears if the Token Ring Bridge is in source route

mode. In the routing information ﬁeld of a packet header, the ring and

Bridge numbers are packed into 16 bit integers. This option determines

how many of the 16 bits are used for the Bridge number portion. The

default value of 4 allows up to 15 Bridges to be connected to the same

set of rings (zero is not an option).

Typically, this parameter is not changed and should only be changed

after consulting with your network administrator.
