Page 9: Chapter 1 Introduction
Introduction The 9T122-24 MicroLAN™ Switch Module, shown in Figure 1-1, is a three port Token Ring bridge and router module. This module supports either one token ring with 24 HUB connections, or two separate Token Rings with 12 HUB connections, and an interface to the FNB backplane. - Page 10 A telnet session can be set up with the module to provide access to the Local Management screens. LANVIEW LEDs The 9T122-24 use LANVIEW – the Cabletron Systems built-in visual diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly identify the device, port, and physical layer status at a glance.

Page 19: Multi-Ring Out Capability
Multi-Ring Out Capability Any port of the module may be configured as a ring-out port through management software. In this configuration a stand-alone passive concentrator (such as an IBM 8228) may be added to the ring as shown in Figure 2-5. This allows for a star-wired network with the SmartSwitch 9000 at the center. - Page 20 Installation...

Page 21: Chapter 3 Operation
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 connects to the FNB bus. -
Page 22: Bridging
If the destination address of a packet resides on the bridge segment, the 9T122-24 does not forward across the Token Ring link. The second filtering process, the Cabletron Systems Special Filtering Database, provides an additional step in the filter/forward decision. Through Remote Management, you can define up to 10 additional filtering parameters for... -
Page 23: Source Route Bridging
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 as the RIF (Routing Information Field), the source device determines the route for the frames it sends. -
Page 24: Flexible Network Bus (Fnb)
Operation Flexible Network Bus (FNB) The FNB consists of two dual FDDI networks, the FNB-1 and FNB-2, providing up to 400 Mbps of data bandwidth. These FDDI networks are 100% ANSI FDDI-compliant supporting SMT (version 7.3), MAC, PHY, and PMD standards. This allows the FNB to traverse multiple SmartSwitch 9000 hubs, or connect to any ANSI FDDI-compliant device, through standard A/B port connections, using the FDDI repeater module. -
Page 25: System Diagnostic Controller
System Diagnostic Controller This diagnostic controller is composed of a Z-80 microprocessor and its supporting logic. The diagnostic controller is designed to control the power-up sequencing of modules, monitor the 9T122-24 input and output power parameters, keep watch over the main host processor, as well as monitor the temperature and control the SMB LANVIEW diagnostic LED. - Page 26 Operation The i960 core provides the SNMP protocol stacks, as well as support for industry- standard MIBs. Additionally, Cabletron enterprise-extension MIBs are supported for each media type. Advanced management services, such as the Distributed LAN Monitor, RMON, telnet and network address to MAC address mapping, are also provided by the i960 core.
