Performing Loopback Tests on the Flex-WAN Serial and Ultra-WAN CSU/DSU Interfaces

test. If your serial line does not pass the test, verify that your PathBuilder
switch is cabled correctly and that the software is configured correctly.
Also, check the number of packets transmitted and the number of errors
by entering:

DLTest STATistics

6

Stop the loopback test by entering:

DLTest Abort

7

Restore the owner of the wide area port you are testing from loopback to
your protocol using:

SETDefault !<port> -PORT OWNer = PPP | FrameRelay | SMDS | Auto

Failure to perform this step causes the port associated with the Flex-WAN
serial or Ultra-WAN CSU/DSU interface to remain in loopback mode
preventing connectivity through the port. Performing diagnostics on the
port will reveal only that the port is down.

Configuring a RX to

TX Loopback via the

Command Line on the

Ultra-WAN CSU/DSU

Interface

This section describes how to configure an Ultra-WAN CSU/DSU
interface, for receive-to-transmit loopback as shown in Figure 45.

Figure 45

RX to TX Loopback Testing Data Flow

Before running the T1/E1 loopback test, attach a console or Telnet to your
PathBuilder switch.

To configure the Ultra-WAN CSU/DSU interface for RX to TX loopback,
follow these steps:

1

Disable all of the paths on the interface by using:

SETDefault !<path> -PATH ConnControl=Disable

2

Start a loopback test by entering one of the following commands.

■

To receive data from the network and loopback data to the network
without performing any framing or deframing, configure a remote
line loopback by entering:

PathBuilder switch
