5. Display the system log (

command). If the feature is operational, some frames similar to the

following will be displayed:

(I) 16:28:49.71 #C021: Conn=001 OUT-PPP:LCP ECHO REQ Id=0x50 Len=10

(I) 16:28:49.71 #0000: 3E 03 78 AC

(I) 16:28:49.76 #C021: Conn=001 IN -PPP:LCP ECHO RPLY Id=0x50 Len=10

(I) 16:28:49.76 #0000: 70 18 D0 87

(I) 16:28:59.82 #C021: Conn=001 OUT-PPP:LCP ECHO REQ Id=0x51 Len=10

(I) 16:28:59.82 #0000: 3E 03 78 AC

(I) 16:28:59.82 #C021: Conn=001 IN -PPP:LCP ECHO RPLY Id=0x51 Len=10

(I) 16:28:59.82 #0000: 70 18 D0 87

6. To determine if the feature detects a failure:

a. Set up two systems in a back-to-back, dedicated, BRI scenario where at least one of the

systems is a PC-Platform. Configure a dedicated access between the 2 systems.

With the a PC-based platform, layer 1 of a BRI board stays active even when you exit the

software. This gives us a way to simulate an end-to-end B-channel failure. That is, the only

remaining way for the other system to detect the error is via the Link Failure Detection

mechanism. (There are no D-channel failures or Layer 1 failures).

b. On the non-PC system (or either of the two if both are PC-platforms), make sure that Link

Failure Detection is enabled. Go to the

screen to make sure that the dedicated

connection is up.

c. On the PC-platform system, enter the

quit

command.

d. On the non-PC system wait for approximately the amount time of the echo frequency

multiplied by the maximum attempts. At this time, the feature should detect the failure,

and the

screen should remove the dedicated connection.

e. Check the log for the message which indicates that a link failure has been detected.

f. If there is a failure, refer to WAN Line Availability for corrective actions.

X.25 CONNECTIONS

To verify an X.25 to the CyberSWITCH, the WAN lines that are connected to the System must be

available for use, and the routing option must be properly initialized.

1. Enter the

x25 stats

command at the administration console. If the statistics display appears,

the X.25 subsystem should be operational.

2. If the message: No X.25 Accesses configured is displayed, verify your configuration.

Using CFGEDIT, verify that the proper line and port have been selected. If you are still having

problems, try the following:

a. Enter the

command to erase the report log.

b. Enter the

trace lapb on

command.
