When you assign an 8250 token-ring module to one of the token-ring networks on the Enhanced TriChannel (tr_8250_1 through tr_8250_7) using the following command:

SET MODULE {slot.sublsot} NETWORK {token_ring_n}

The 8260 will automatically allocate one of the available token-ring paths to this module. Note that you can neither choose the path used by the module, nor determine which path is used by a specific module. However, you can determine all token-ring paths on the Enhanced TriChannel which are currently being allocated in your hub by using the following management module command:

SHOW BACKPLANE_PATHS TOKEN_RING

An example of the output from this command is shown in Figure 6.

The number of token-ring paths used by a single token-ring network on the Enhanced TriChannel equals the number of token-ring modules on that network.

Note that the token-ring paths on the Enhanced TriChannel use the same pins on the backplane as are used by the Ethernet and/or FDDI segments. Therefore, simultaneous configuration of other types of networks in your hub will impact the number of token-ring networks allowed in your hub. In Figure 6, the token-ring paths shown as in in useare those backplane pins that are used by other segment types (that is, Ethernet or FDDI), whereas tr_path_8250_7,

tr_path_8250_9 and tr_path_8250_13 are used to configure a single token-ring segment (tr_8250_1) consisting of three 8250 token-ring modules. Also, note that
