262 CHAPTER 11: SYSTEM MANAGEMENT

Table 292 Log Output (continued)

Operation	Command
Set the address of the interface specified by	info-center loghost source
interface-name as the source address for	interface-name
packets sent to loghost
Cancel the source address setting for the	undo info-center loghost source
packets sent to loghost

Configure to output the information to the trap buffer.

info-center trapbuffer [ size buffersize ] [ channel { channel-number channel-name } ]

Disable the output of the information to the	undo info-center trapbuffer [
trap buffer.	channel size ]

Configure to output the information to SNMP. info-center snmp channel { channel-number channel-name }

Disable the output of the information to	undo info-center snmp channel
SNMP.
Rename a channel specified by	info-center channel
channel-number as channel-name	channel-number name channel-name

The system assigns a channel in each output direction by default. See Table 293.

Table 293 Numbers and Names of the Channels for Log Output

Name	Channel number	Default channel name
Console	0	console
Monitor	1	monitor
Info-center loghost	2	loghost
Trap buffer	3	trapbuf
Logging buffer	4	logbuf
SNMP	5	snmpagent

The six settings are independent from each other. The settings will take effect only after enabling the information center.

Defining the Log Filtering Rules

The SYSLOG classifies the information into eight levels of severity. The log filtering prevents the system from outputting information whose severity level is greater than the set threshold. The more urgent the logging packet is, the lower its severity level. The level for emergencies is 1, and the level for debugging is 8. Therefore, when the threshold of the severity level is 8, the system will output all information.

Table 294 Syslog-Defined Severity

Severity		Description
1	Emergencies	The extremely urgent errors that endanger
		data.
2	Alerts	The errors that need to be corrected
		immediately.
3	Critical	Critical errors
4	Errors	The errors that need to be addressed but are
		not critical
