Figure 45. The Sample Console Screen to Check the Physical Connection

Notes:

￿1￿ This SHOW PORT command was issued when the physical cabling has been done but the remote device is power off.

￿2￿ You can get the status shown in several lines, but the main status is shown in the first line. The UP-NO ACTIVITY means the status physical cabling is done but no physical layer activity is detected.

￿3￿ This SHOW PORT command was issued when the physical connection was up and the remote device is been ready.

￿4￿ The UP-OKAY means the remote device is attached to the ATM network.

The typical reasons an ATM device might be unable to make a physical connection are as follows:

Cabling

If a fiber cable is used, check to see if the each end of the cable is connected to the appropriate connector, transmit or receive. And if a copper cable is used, check to see that the pinouts of the cable and each end of the cable are matched, especially when you use a non-Forum-compliant adapter or the connection is between ATM switches.
