Introduction
1.6.3 IPX with Token Ring Source Routing
Token ring networks often interconnect with source routing (SR)
bridges. Although the source routing is a MAC layer feature, all
packets must provide the correct source route information to the
bridges in order to traverse the networks. To successfully and
efficiently route network traffic in such environments, routers need
to have the capability to explore and select routes, cache and age
route information, and construct network packets with the proper
route information. Support of IPX over source routing (IPX SR)
enables the ATX LAN switch to achieve this capability and route
IPX packets through SR bridges.
See section 3.11 IPX Routing Over
Source Route Comands for additional information on source routing
commands.
1.6.4 Event Logging on the ATX
Event Logging is an ATX troubleshooting tool. It records selected
classes of networking events then analyzes the log of events
recorded to assist in diagnosing problems on the network. ATX
Event Logging includes the following features:
• Separate enabling flags for each event or class of events. The
enabling flags are symbolic and are thus easily used in
troubleshooting the network.
• Continuous monitoring of events is supported.
• Logging entries are easy to add and delete from the source code.
• The framework is integrated with SNMP and easily fits into the
anticipated fault/alarm restructuring.
See section 3.14 Event Logging Commands for additional
information on Event Logging.
1.6.5 ATX LAN Switch Workgroups
Virtual workgroups allow you the flexibility to control broadcasts
in the network. By reducing broadcasts throughout the network, it
