Parameters

module-name: Specifies a module by its name. You can use the info-center source ? command to view the modules supported by the device.

default: Specifies all supported modules.

console: Outputs logs to the console.

logbuffer: Outputs logs to the log buffer.

loghost: Outputs logs to the log host.

monitor: Outputs logs to the monitor terminal.

deny: Disables log output.

level severity: Specifies a severity level in the range of 0 to 7. The smaller the severity value, the higher the severity level. See Table 1 for more information. Logs at the specified severity level and higher levels are allowed to be output.

Usage guidelines

If you do not set an output rule for a module, the module uses the output rule set by using the default keyword. If no rule is set by using the default keyword, the module uses the default output rule.

To modify or remove an output rule set for a module, you must use the module-name argument. A new output rule configured by using the default keyword does not take effect on the module.

If you execute this command for a module multiple times, the most recent configuration takes effect.

If you execute this command for the default modules multiple times, the most recent configuration takes effect.

Usage guidelines

System log output interrupts ongoing configuration operations, including obscuring previously entered commands. Synchronous information output shows the obscured commands. It also provides a command prompt in command editing mode, or a [Y/N] string in interaction mode so you can continue your operation from where you were stopped.

Examples

# Enable synchronous information output, and then execute the display current-configuration command to view the current configuration of the device.

<Sysname> system-view

[Sysname] info-center synchronous

Info-center synchronous output is on

[Sysname] display current-

At this time, the system receives log information. It displays the log information first, and then displays your previous input, which is display current- in this example.

%May 21 14:33:19:425 2007 Sysname SHELL/5/SHELL_LOGIN: VTY logged in from 192.168.1.44

[Sysname] display current-

Enter configuration to complete the display current-configuration command, and press the Enter key to execute the command.

# Enable synchronous information output, and then save the current configuration (enter interactive information).

<Sysname> system-view

Predefined user roles

network-admin

Parameters

buffersize: Specifies the maximum number of log traps that can be stored in the log trap buffer. The value range is 0 to 65535. Value 0 indicates that the device does not buffer log traps.

Usage guidelines

Log traps are SNMP notifications stored in the log trap buffer. After the snmp-agent trap enable syslog command is configured, the device sends log messages in SNMP notifications to the log trap buffer. You can view the log traps by accessing the MIB corresponding to the trap buffer.

The default buffer size is usually used. You can adjust the buffer size according to your network condition. New traps overwrite the oldest traps when the log trap buffer is full.

Examples

# Set the log trap buffer size to 2048.

<Sysname> system-view

[Sysname] info-center syslog trap buffersize 2048

Default

The device does not send SNMP notifications for log messages.

Views

Predefined user roles

network-admin

Usage guidelines

This command enables the device to send an SNMP notification for each log message it outputs. The device encapsulates logs in SNMP notifications and then sends them to the SNMP module and the log trap buffer.

For the SNMP module to send the received SNMP notifications correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see the network management and monitoring configuration guide for the device.

To view the traps in the log trap buffer, access the MIB corresponding to the log trap buffer. The log trap buffer size can be set by using the info-center syslog trap buffersize command.

Examples

# Enable the device to send SNMP notifications for log messages.

<Sysname> system-view

[Sysname] snmp-agent trap enable syslog

Predefined user roles

network-admin

Usage guidelines

This command enables output of debugging-level log messages to the current terminal.

To enable output of debugging messages to the console, perform the following tasks:

1.     Execute the terminal debugging command.

2.     Enable the information center. The information center is enabled by default.

3.     Use a debugging command to enable the related debugging.

To enable output of debugging messages to the monitor terminal, perform the following tasks:

1.     Execute the terminal monitor and terminal debugging commands.

2.     Enable the information center. The information center is enabled by default.

3.     Use a debugging command to enable the related debugging.

This command takes effect only for the current connection between the terminal and the device. If a new connection is established, the default is restored.

You can also enable output of debugging messages to the current terminal by executing the terminal logging level 7 command. The terminal logging level 7 command and the terminal debugging command have the following differences:

·     The terminal logging level 7 command enables log output for all log severity levels (levels 0 through 7).

·     The terminal debugging command enables log output for the following log severity levels:

¡     Debugging level (level 7).

¡     Severity level higher than or equal to the level specified in the terminal logging level command.

Examples

# Enable output of debugging messages to the current terminal.

<Sysname> terminal debugging

The current terminal is enabled to display debugging logs.

Parameters

severity: Specifies a log severity level. Valid values are alert, critical, debugging, emergency, error, informational, notification, warning, and digits from 0 to 7.

Usage guidelines

This command enables the device to output logs with a severity level higher than or equal to the specified level to the current terminal. For example, if you set the severity argument to 6, logs with a severity value from 0 to 6 are output to the current terminal.
