SYSLOG Messages
The SYSLOG contains an historical list of special system messages which serves
as a log of certain significant events that occur in the DSL network. SYSLOG
messages consist of a date and timestamp, followed by the message.
To view SYSLOG messages, access the SYSLOG menu entry (B-A-C).
Example SYSLOG Messages
Interpreting SYSLOG messages sometimes involves viewing a series of
messages to determine the problem. Event messages can indicate that certain
thresholds have been exceeded.
By comparing the embedded timestamp received from the remote unit to the
timestamp in the port card message, you can determine which end of the DSL link
entered the retrain state first, and which simply reacted to the training sequence
from the other end. The port card SYSLOG message always appears first.
See the following examples.
Example 1. Port Card (Upstream Channel) Retrain
The following SYSLOG messages have been received:
02/18/2000 09:53:26 S/N Threshold Reached, port DSL port 4
02/18/2000 09:53:50 Remote Restarted at 02/18/2000 09:53:34
02/18/2000 09:53:50 Remote Reed Solomon Restart, Port 4
Meaning:
The upstream Signal-to-Noise (S/N) ratio has dropped below the acceptable
threshold and the port card has retrained. The remote unit retrain has occurred
after the port card retrain.

NOTE:
Some actions through the user interface can cause an error message to
appear on the screen. However, this message is not necessarily logged in the
SYSLOG. If the LOG_ERR level is set, only selected messages appear in the
SYSLOG. For example, if you enter a wrong filename during a configuration
upload or download, this error is not logged in the SYSLOG if the error level is
set to LOG_ERR. The System Administrator can choose to change the error
level to log less severe errors, if this is deemed to be necessary.
