Information Output

Information generated by the device can be output to a remote terminal, console, log buffer, log file, or SNMP agent. To output information in different directions, 10 information channels are defined for the information center. These channels work independently from one another. You can configure output rules so that information is output through different channels in different directions based on information type and severity level. An example is shown in Figure 1.

Figure 1 Information center

By default, logs, traps, and debugging messages are output through default channels. You can change names of the channels as well as the relationships between channels and output directions as required. For example, you can set the name of channel 6 to user1 and configure channel 6 to send information to the log host. The information sent to the log host is then output through channel 6 instead of the default channel 2.

Table 1 lists channel numbers, default channels of information, and descriptions.

**Table 1** Relationships between default channels and output directions
Channel Number	Default Channel Name	Output Direction	Description
0	console	Console	Outputs logs, traps, and debugging messages to the local console.
1	monitor	Remote terminal	Outputs logs, traps, and debugging messages to a VTY terminal for remote maintenance.
2	loghost	Log host	Outputs logs, debugging messages, and traps. The information is saved to the log host in file format for easy reference.
3	trapbuffer	Trap buffer	Outputs traps.
4	logbuffer	Log buffer	Outputs logs.
5	snmpagent	SNMP agent	Outputs traps.
6	channel6	Unspecified	Reserved. You can specify an output destination for this channel.
7	channel7	Unspecified	Reserved. You can specify an output destination for this channel.
8	channel8	Unspecified	Reserved. You can specify an output destination for this channel.
9	channel9	Logfile	Outputs logs, debugging messages, and traps.
