Command Descriptions, Continued

“display links” Command

This command displays the hub-half’s link state table. The link state table indicates, for each link, whether or not the link is currently “connected,” “unconnected,” or undergoing link validation (“validation”). For DataNET links (including the cross-link), the table also gives the device to which the link connects. DataNET devices are identified by their device IDs.

Example: local> display In this example, port 7 is running in diagnostic mode (see “test” com-

linksmand) and port 1 is validating its link to device 8.8.8.8. Port 5 has been taken offline, either with the “port stop” command, or because the hub detected a loop in the DataNET topology.

“download” Command

If a hub port is connected to an Advance Network Gateway with Data- NET the display link command will also provide enhanced configuration information when the link number is specified

Use this command to load new firmware into the hub-half via the RS-232 Configuration port. The procedure for firmware download is:

1.Make sure you have a “hub_rom.mot” file available for download.

2.Log into the target Hub through the Configuration port, using Hyper- Term.

3.Type “download” at the hub’s prompt (“>”). The hub will then prompt to begin transmitting the download file.

4.Transmit the download file. Use the HyperTerm “Transfer --> Send Text File…” command. Find the “hub_rom.hex” file using the browser window. You may have to select “Show all files” in the “Files of type” window to see the “hub_rom.mot” file.
