Troubleshooting a Synchronous Connection
This section assumes that you have isolated a problem to a synchronous
connection. If not, refer to Chapter 2 to determine whether these instructions
apply to your problem.
Troubleshoot a synchronous connection as follows:
1. Filter the log to display only messages from the Sync entity running on
the slots experiencing the problem.
The Technician Interface command is as follows:
log -fftwid -eSYNC -s
<slot_no.>
Example
If you are filtering events from slots 3 and 4, enter the following command:
log -fftwid -eSYNC -s3 -s4
If you see a message like the following, see “Troubleshooting the Internal
Clock Settings (Lab Environments Only)” later in this chapter:
Warning Sync Code: 40 "Connector COM2: clock speed does not
match other ports."
2. Use the Technician Interface to look at the values of the following
attributes in the wfSyncEntry object:
wfSyncRuntsRx (
get wfSyncEntry.51.*)
This shows the number of frames received that are smaller than the
minimum length. It usually indicates a clocking problem on the line.
wfSyncBadFramesRx (
get wfSyncEntry.49.*)
This shows the frames received that were unrecognizable. It may indicate
underflow errors or an out-of-phase clock on the remote side.
Note: The get command is next to the attribute name. Or, use the Quick Get
path wfLine > wfSyncTable.
