LRE Message Logging Process

The Catalyst 2950 LRE switch software monitors switch conditions on a per-port basis and sends the
debugging messages to an LRE message logging process that is different than the system message
logging process described in Chapter27, “Configuring System Message Logging.”
These options are available in the LRE logging process:
•Disabled—The switch does not log LRE events.
•Event—The switch logs only LRE events.
•Extended—The switch logs LRE events and all the LRE parameters.
•Normal—The switch logs LRE events and the typical LRE parameters.
You can use the logging lre interface configuration command to specify the mode in which to log LRE
events. To display the events on the LRE interfaces, use the show controllers lre log privileged EXEC
command. For more information about these commands, refer to the command refere nce for this release.
If the syslog export feature is enabled, the switch sends the infor mat ion to t he LRE me ssag e l oggin g
process and to the system message logging process. For informati on about configuring this feature, see
the “Configuring Syslog Export” section on page 13-22.
