Parameters
terminal: Displays the character set encoding used on the login terminal. If you do not specify this keyword, this command displays the character set encoding used on the device. By default, the device uses the GB18030 encoding and the encoding cannot be changed.
Usage guidelines
For the user' login terminal to correctly display Chinese characters in log messages received from the device, the device and the terminal must use the same character set encoding.
Use the display character-set terminal command to identify the character set encoding used on the login terminal. The device will send test characters in both UTF-8 and GB18030 encodings to the terminal. The test characters will be displayed as 中文 for the character set encoding used on the terminal.
Examples
# Display the character set encoding used on the device.
<Sysname> system-view

Parameters
filter-name: Specifies a name for the log output filter, a case-insensitive string of 1 to 8 characters.
module-name: Specifies a module by its name. To view the names of supported modules, execute the info-center filter filter-name ? command.
default: Specifies all supported modules.

level severity: Specifies a log severity level by its name. Supported severity levels are alert, critical, debugging, emergency, error, informational, notification, and warning. See Table 4 for more information about the log severity levels. The log output filter applies to logs of the specified severity level and all higher levels.
Usage guidelines
A log output filter contains a set of log output filter rules for modules. You can create multiple log output filters. When specifying a log host, you can apply a log output filter to control log output to the log host.
You can also use the info-center source command to configure log output rules for the log host output destination. The system chooses the settings to control log output to a log host in the following order:
1. Log output filter specified for the log host by using the info-center loghost command.
2. Log output rules configured for the log host output destination by using the info-center source command.
3. Default log output rules (see Table 7).
Follow these restrictions and guidelines when you configure a log output filter:
· To set a log output filter rule for a module, use the module-name argument to specify the module name.
If you set log output filter rules for the same module multiple times, the most recent configuration takes effect.
· To set a general log output filter rule for all modules, use the default keyword. The general log output filter rule applies to all modules that do not have module-specific filter rules.
If you set a general log output filter rule multiple times, the most recent configuration takes effect.
· If no general log output filter rule is set, the system outputs logs with severity levels informational through alert for modules that do not have module-specific filter rules.
· To remove a module-specific log output filter rule, you must use the module-name argument. You cannot use the default keyword to remove module-specific log output filter rules. If you do not specify any parameters, the entire log output filter is deleted.
Examples
# Create log output filter loghost1. In the log output filter, enable the ARP module to output logs with severity levels notification through alert, enable the DHCP module to output logs with severity levels warning through alert, and disable log output of all other modules.
<Sysname> system-view

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.
