If your ProCurve Secure Router is providing several WAN connections for your
company, you may want to view a list of these connections. The show
connections command provides a quick view of all the connections on the
router. As Figure 5-9 shows, this command lists the logical interface and the
physical interface for each connection.
You enter the show connections command from the enable mode context.

Troubleshooting a Serial Connection
When you troubleshoot a serial interface, you should isolate the problem to
determine if it is a problem with the Physical Layer or the Data Link Layer.
Follow this standard process for troubleshooting WAN connections:
1. Check the Physical Layer.
a. Check whether the serial interface is up or down.
b. Check the configurations to ensure that you are using the correct
settings.
c. Check the cabling, the connections, and other hardware.
d. Check the CSU/DSU settings and compare these settings against
those used for the serial interface.
