Description
Use the display logbuffer command to view the attribute of logbuffer and the information recorded in logbuffer.
All log messages are saved in the log buffer. When the log buffer is full, the latest message will overlap the earliest one.
The displaying sequence of all log messages is from the newest message to the oldest one.
When you input size, if the size of current configured log messages is bigger than the logsize, the system will search for the messages on the following principles.
l If you input reverse, the system will search for logsize matching messages from the oldest one( the head of the log buffer), then displays them from the newest message to the oldest one.
l If you do not input inverse, the system will search for the logsize matching messages from the newest one( the end of the log buffer), then displays them from the newest message to the oldest one.

& Note:
If you only specify the level for one/two of the three types of information, the level(s) of the unspecified two/one return(s) to the default. For example, if you only define the level of the log information, then the levels of the trap and debugging information return to the defaults.
channel-number: Channel number to be set.
channel-name: Channel name to be set. The name can be channel7, channel8, channel9, console, logbuffer, loghost, monitor, snmpagent, trapbuffer, logfile.
state: Sets the state of the information.
state: Specifies the state as on or off.
Description
Use the info-center source command to add/delete a record to the information channel.
Use the undo info-center source command to cancel the contents of the information channel.
Use this command to configure the information of log/trap/debugging type. For example, for the filter of IP module log output, you can configure to output the logs at a level higher than warnings to the log host and output those higher than informational to the log buffer. You can also configure to output the trap information on the IP module to a specified trap host, and so on.
The channels for filtering in all the directions are specified by this configuration command. All the information will be sent to the corresponding directions through the specified channels. You can configure the channels in the output direction, channel filter information, filtering and redirecting of all kinds of information.
At present, the system distributes an information channel in each output direction by default, shown as follows:

In addition, each information channel has a default record with the module name “default” and module number as 0xffff0000. However, for different information channel, the default log, trap and debugging settings in the records may be different with one another. Use default configuration record if a module does not have any specific configuration record in the channel.
Examples
# Set to enable the log information of VLAN module in SNMP channel and allow the output of the information with a level higher than emergencies.

1.1.16 info-center timestamp
Syntax
info-center timestamp { log | trap | debugging } { boot | date | none }
undo info-center timestamp { log | trap | debugging }
View
System view
Parameters
log: Log information.
trap: Trap information.
debugging: Debugging information.
boot: Time elapsing after system starts. Format: xxxxxx.yyyyyy, xxxxxx is the high 32 bits of the elapsed time (in milliseconds) after system starts, and yyyyyy is the low 32 bits.
date: Current system date and time. It shows as yyyy/mm/dd-hh:mm:ss in Chinese environment and mm dd hh:mm:ss yyyy in Western language environment.
none: No timestamp format.
Description
Use the info-center timestamp command to configure the timestamp output format in debugging/trap information.
Use the undo info-center timestamp command to disable the output of timestamp field.
By default, date stamp is used.
Examples
# Configure the debugging information timestamp format as boot.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] info-center timestamp debugging boot
1.1.17 info-center trapbuffer
Syntax
info-center trapbuffer [ size buffersize | channel { channel-number | channel-name } ]*
undo info-center trapbuffer [ channel | size ]
View
System view
Parameters
size: Configures the size of the trap buffer.
buffersize: Size of trap buffer (numbers of messages).
channel: Configures the channel to output information to trap buffer.
channel-number: Channel number, ranging from 0 to 9, that is, the system has ten channels.
channel-name: Channel name which can be the channel7, channel8, channel9, console, logbuffer, loghost, monitor, snmpagent, trapbuffer, logfile
Description
Use the info-center trapbuffer command to output information to the trap buffer.
Use the undo info-center trapbuffer command to cancel output information to trap buffer.
By default, output information is transmitted to trap buffer and size of trap buffer is 256, that is, the trap buffer can hold 256 messages.
This command takes effect only after the system logging is enabled.
The information can be output to the trap buffer by configuring the size of the buffer.
Related commands: info-center enable, display info-center.
Examples
# Send information to the trap buffer and sets the size of the buffer to 30.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] info-center trapbuffer size 30

Parameters
None
Description
Use the terminal debugging command to configure to display the debugging information on the terminal.
Use the undo terminal debugging command to configure not to display the debugging information on the terminal.
By default, the terminal display function of debugging information is disabled.
Related commands: debugging.

Parameters
None
Description
Use the terminal logging command to enable terminal log information display.

1.1.22 terminal monitor
Syntax
terminal monitor
undo terminal monitor
View
User view
Parameters
None
Description
Use the terminal monitor command to enable the terminal display functions.
Use the undo terminal monitor command to disable the terminal display functions.
By default, the system enables the functions of debugging/log/trap information on the console and disables them on the terminal.
This command only takes effect on the current terminal where the commands are input. The debugging/log/trap information can be output to the current terminal, beginning in user view. When the terminal monitor is shut down, no debugging/log/trap information will be displayed in local terminal, which is equals to having performed undo terminal debugging, undo terminal logging, undo terminal trapping commands. When the terminal monitor is enabled, you can use terminal debugging / undo terminal debugging, terminal logging / terminal logging and terminal trapping / undo terminal trapping respectively to enable or disable the corresponding functions.
Examples
# Disable the terminal monitor.
<H3C> undo terminal monitor
1.1.23 terminal trapping

User view
Parameters
None
Description
Use the terminal trapping command to enable terminal display function of trap information.
