Parameters

Parameter	Description	Value
channel-number	Specifies the channel number.	The value is an integer ranging from 0 to 9, indicating that the system has 10 channels. By default, a device outputs information to various destinations through channels listed in the following table. channel number:0, channel name:console, output destination:console. channel number:1, channel name:monitor, output destination:remote terminal. channel number:2, channel name:loghost, output destination:syslog server. channel number:3, channel name:trapbuffer, output destination:trap buffer. channel number:4, channel name:logbuffer, output destination:log buffer. channel number:5, channel name:snmpagent, output destination:SNMP agent. channel number:6, channel name:channel6, output destination:unspecified. channel number:7, channel name:channel7, output destination:unspecified. channel number:8, channel name:channel8, output destination:unspecified. channel number:9, channel name:channel9, output destination:unspecified.
channel-name	Specifies the name of a channel, which can be the default channel name or a user-defined name.	The value is a string of 1 to 30 characters. The first character can be a letter only. The name cannot contain spaces or special characters, such as hyphens (-), slashes (/), or backslashes (\).

Usage Guidelines

Usage Scenario

To set the number of traps to be output, run the info-center trapbuffer size command.

To output the same information to destinations or output information from multiple channels to the same destination, run the info-center command to modify configurations about information channels. The following requirements can be met:

Outputting the same information to destinations. For example, the information recorded by information files and the syslog server can be identical with that recorded by the trap buffer and the SNMP agent.
Outputting information through each channel to a specific syslog server. For example, information can be output through channel 7 to a syslog server with IP address 192.168.0.1, but through channel 8 to a syslog server with IP address 192.168.0.2.

Prerequisites

The trap display function has been enabled. Otherwise, traps cannot be output to the trap buffer for user query.

Configuration Impact

If the info-center trapbuffer size command is run more than once, the latest configuration overrides the previous one.

Precautions

If the number of traps to be displayed is set too small, some traps cannot be queried. If the number of traps to be displayed is set too large, excessive repeated traps may be displayed. The default number of traps to be displayed is recommended.

Example

# Configure the channel through which information is output to an SNMP agent.
