Chapter 30 Configuring System Message Logging
Configuring System Message Logging
Note Specifying a level causes messages at that level and numerically lower levels to appear at the destination.
To disable logging to the console, use the no logging console global configuration command. To disable
logging to a terminal other than the console, use the no logging monitor global configuration command.
To disable logging to syslog servers, use the no logging trap global configuration command.
Table 30-3 describes the level keywords. It also lists the corresponding UNIX syslog definitions from
the most severe level to the least severe level.
The software generates four other categories of messages:
• Error messages about software or hardware malfunctions, displayed at levels warnings through
emergencies. These types of messages mean that the functionality of the switch is affected. For
information on how to recover from these malfunctions, see the system message guide for this
release.
• Output from the debug commands, displayed at the debugging level. Debug commands are
typically used only by the Technical Assistance Center.
• Interface up or down transitions and system restart messages, displayed at the notifications level.
This message is only for information; switch functionality is not affected.
Step 4
logging trap level Limit messages logged to the syslog servers.
By default, syslog servers receive informational messages and
numerically lower levels (see
Table 30-3 on page 30-9).
For complete syslog server configuration steps, see the “Configuring
UNIX Syslog Servers” section on page 30-12.
