The Bridge Config utility allows you to enable or disable Spanning Tree for your
TSX-1620, as well as define a group destination (multicast) MAC address to be
used in implementing the source routing function. To access the Bridge Config
window:
1. Click on the module index or module type to display the Module menu (see
Figure 2-3 on page 2-5).

Figure 2-8. The Bridge Config Window
To enable or disable Spanning Tree using the Bridge Config window:
1. Click on the Spanning Tree: Enable or Disable option, as desired. Spanning
Tree will be enabled or disabled for the TSX-1620, depending on your
selection. The default selection is Disable.
The Destination MAC address must be one of two group destination MAC
addresses, as defined by the Source Routing specification. A frame containing the
destination group address value c0:00:00:00:01:00 will be received by all stations
on the sending station’s ring. A frame containing the destination group address
value 80:41:00:00:00:00 will be received by all stations on all rings in a multi-ring
network. To define or change the group destination (multicast) MAC address to
be used in implementing the source routing function:
1. Highlight the contents of the Destination MAC field. Type the desired group
destination MAC address in Canonical (Token Ring) format, and then press
Enter or Return on your keyboard.
