This is not true for Token Ring and FDDI networks and paths. There are 7 available Token Ring networks and 15 Token Ring paths. For FDDI, there are 4 available FDDI networks and 8 FDDI paths. When you assign a module or port to a network, the master management module dynamically allocates the best possible path currently available for your configuration.

Following Figure 1-3 are Table 1-1, Table 1-2, and Table 1-3, which provide reference tables for configuring Ethernet, Token Ring, and FDDI networks in one concentrator. These tables define which networks paths are removed when certain network paths are used. Refer to these charts to determine the number and types of different protocol combinations you can have in one concentrator.

You may want to issue the SHOW NETWORK PATHS command before and after you configure networks to modules or ports to display which network paths are in use.
