SET MODULE {slot.sublsot} NETWORK {ethernet_n} or

SET PORT {slot.port} NETWORK {ethernet_n}

Before assigning the port or module to a network you may use the following management command to display the availability of the Ethernet segments on the Enhanced TriChannel and the ShuntBus:

SHOW BACKPLANE_PATHS ETHERNET

An example of the output from this command is shown in Figure 5.

In this example, the Ethernet segments shown in useare not available to be used for setting up Ethernet segments in this hub due to the backplane pins corresponding to these segments being currently used by other segment types such as token-ring and/or FDDI. Ethernet_1 and ethernet_5 through ethernet_8 are currently configured to be used by Ethernet modules in this hub. The pins available to be used by ethernet_4 are not currently configured to be used by any network type.

To connect and use the Ethernet segments on the backplane (Enhanced TriChannel or ShuntBus) various techniques are used by the various 8250 and 8260 Ethernet modules. These techniques can be categorized into one of the three following methods:

Method 1:

This method uses 14 pins on the backplane to set up an Ethernet segment. In this method, each module attached to the Ethernet segment will send the slot-id and port-id of the transmitting station in parallel over the backplane.

The slot-id will use 5 pins and the port-id will use 4 pins on the backplane as shown in Table 2 on page 17.

The slot-id will be used to perform digital collision detection as described in 2.2.1, ªDigital Collision Detectionº on page 19. Additionally, the slot-id and the port-id will be used by the management module to perform statistics gathering about the segment as well as the individual ports and modules on that segment as described in 2.2.3, ªStatistics Collectionº on page 19.

This method is used by all 8250 modules and is only allowed on ethernet_1, ethernet_2, and ethernet_3 segments on the Enhanced TriChannel. Therefore, the 8250 Ethernet modules installed in the 8260 can only be assigned to these three segments and can not be assigned to Ethernet
