Chapter 27 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 27-3 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 that appear 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, refer to 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.

• Reload requests and low-process stack messages, displayed at the informational level. This

message is only for information; switch functionality is not affected.
