Chapter 3 Configuration Rules for BayStack Hubs
This chapter provides network configuration and Ethernet compliance
guidelines for BayStack 100-series hubs.
Network Configuration Decisions
When you design a network of BayStack 100-series hubs, take these
restrictions into consideration:
• Make sure your stack conforms to the BayStack 100-series hub stacking
guidelines (next section).
• Make sure the new connections do not exceed the Simple Rules for
Ethernet Network Compliance for your network (pa
ge 2).
• Make sure all connections are within their cable length limits.
For complete information about cable length limits for Ethernet
netoworks, refer to the Bay Networks Connectivity Guide.
Address these issues in conformance with the guidelines that follow.
BayStack Hub Stacking Guidelines
The following guidelines apply when building a stack of 100-series hubs:
• A stack must not exceed 10 hubs, including all remote hubs and cascades.
A stack can be configured as a single cascade or multiple cascades joined
by management extension cable.
• The total distance between all cascades in the stack must not exceed 100
meters. For more information about using the management extension
ports, see “Extending Management to Remote Cascades” on page 2-9.
• At least one in every four hubs in the stack must be powered on to function
correctly. Bay Networks recommends that you connect power to the top
hub first and continue down the stack.
NOTE: Although any one BayStack stack is limited to 10 hubs, your
network can include as many hubs and stacks as your configuration and
the Ethernet Network Compliance rules allow.
