Enabling System Logging
The wireless bridge supports a logging process that can control error messages
saved to memory or sent to a Syslog server. The logged messages serve as a
valuable tool for isolating wireless bridge and network problems.
System Log Setup – Enables the logging of error messages.
Logging Host – Enables the sending of log messages to a Syslog server host.
Server Name/IP – The IP address or name of a Syslog server.
Logging Console – Enables the logging of error messages to the console.
Logging Level – Sets the minimum severity level for event logging.
The system allows you to limit the messages that are logged by specifying a
minimum severity level. The following table lists the error message levels from the
most severe (Emergency) to least severe (Debug). The message levels that are
logged include the specified minimum level up to the Emergency level.
Note:
The wireless bridge error log can be viewed using the Event Logs window in
the Status section (page 5-36).The Event Logs window displays the last 128
messages logged in chronological order, from the newest to the oldest. Log
messages saved in the wireless bridge’s memory are erased when the
device is rebooted.
