Page 21 - Chapter 3; Operation
3-1 Chapter 3 Operation The 9T122-24 MicroLAN Module provides connectivity between the front panel Token Ring(s) and the FDDI rings on the backplane (FNB-1 or FNB-2). SmartSwitch 9000 modules connect to either the Internal Network Bus (INB) or the Flexible Network Bus (FNB) bus. The 9T122-24 module ...
Page 22 - Bridging; Transparent Bridging
Operation 3-2 Bridging The 9T122-24 is configured for SRT bridging. It will pass SR (Source Routing) frames between the rings and provides translation to transparent frames over the FNB to Ethernet and FDDI modules. For information on configuring the bridging function, see the addendum to the SmartS...
Page 23 - Source Route Bridging; Spanning Tree Algorithm
3-3 Operation Source Route Bridging Source Route Bridging operates by transmitting frames over a designated route. Unlike Transparent Bridging, all devices in a Source Route Bridged (SRB) network “know” the locations of other stations within the network. Using a portion of the MAC frame header known...
