Configuring System Message Logging

Table 32-3describes the level keywords. It also lists the corresponding UNIX syslog definitions from the most severe level to the least severe level.

Table 32-3	Message Logging Level Keywords
Level Keyword		Level	Description	Syslog Definition
emergencies		0	System unstable	LOG_EMERG
alerts		1	Immediate action needed	LOG_ALERT
critical		2	Critical conditions	LOG_CRIT
errors		3	Error conditions	LOG_ERR
warnings		4	Warning conditions	LOG_WARNING
notifications		5	Normal but significant condition	LOG_NOTICE
informational		6	Informational messages only	LOG_INFO
debugging		7	Debugging messages	LOG_DEBUG

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.

•Reload requests and low-process stack messages, displayed at the informational level. This message is only for information; switch functionality is not affected.

Limiting Syslog Messages Sent to the History Table and to SNMP

If you enabled syslog message traps to be sent to an SNMP network management station by using the snmp-server enable trap global configuration command, you can change the level of messages sent and stored in the switch history table. You also can change the number of messages that are stored in the history table.

Messages are stored in the history table because SNMP traps are not guaranteed to reach their destination. By default, one message of the level warning and numerically lower levels (see Table 32-3 on page 32-10) are stored in the history table even if syslog traps are not enabled.
