1.1.3 display logbuffer

Syntax

display logbuffer [ level severity | size buffersize ] * [ | { begin | exclude | include } text ]

View

Any view

Parameters

level severity: Displays information of the log with specified level, where severity represents information level, in the range 0 to 7.

Table 1-4 Severity description

Severity	Value	Description
emergencies	0	The system is unavailable
alerts	1	Information that requires prompt reaction
critical	2	Critical information
errors	3	Error information
warnings	4	Warnings
notifications	5	Normal errors with important information
informational	6	Informational information to be recorded
debugging	7	Debugging information

size buffersize: Displays specified number of the latest log messages in the log buffer, where buffersize represents the number of the latest log messages to be displayed in the log buffer, in the range 1 to 1,024.

|: Uses a regular expression to filter the output information. For detailed information about regular expression, refer to section CLI Display in System Maintaining and Debugging Configuration.

begin: Displays log information beginning from a specific line, which must contains the specified regular expression.

exclude: Displays log information lines that do not contain the specified regular expression.

include: Displays log information lines containing the specified regular expression.

text: Regular expression, a string of 1 to 256 characters, case sensitive.

Table 1-5 Meanings of characters in text

Character	Meaning	Remarks
^	Starting sign, the string following it appears only at the beginning of a line.	Regular expression “^user” matches a string begins with “user”, not “Auser”.
$	Ending sign, the string before it appears only at the end of a line.	Regular expression "user$” matches a string ends with “user”, not “userA”.
.	Full stop, a wildcard used in place of any character, including blank	None
*	Asterisk, used to match a subexpression before it zero or multiple times	zo* can map to “z” and “zoo”.
+	Addition, used to match a subexpression before it one or multiple times	zo+ can map to “zo” and “zoo”, but not “z”.
-	Hyphen. It connects two values (the smaller one before it and the bigger one after it) to indicate a range together with [ ].	For example, “1-9” means numbers from 1 to 9 (inclusive); “a-h” means from a to h (inclusive).
[ ]	Selects one character from the group.	For example, [1-36A] can match only one character among 1, 2, 3, 6, and A.
( )	A group of characters. It is usually used with “+” or “*”.	For example, (123A) means a string “123A”; “408(12)+” can match 40812 or 408121212. But it cannot match 408. That is, “12” can appear continuously and it must at least appear once.

View

System view

Parameters

module-name: Specifies the output rules of the system information of the specified modules, which vary with devices. For instance, if information on ARP module is to be output, you can configure this argument as ARP.

default: Specifies the output rules of the system information of all the modules allowed to output the system information. This configuration varies with devices.

debug: Debugging information.

log: Log information.

trap: Trap information.

level severity: Specifies the severity of system information, refer to Table 1-4 for details.

state state: The state of system information output, which could be on (enabled) or off (disabled).

channel-number: Specifies a channel number, in the range 0 to 9.

Description

Use the info-center source command to specify the output rules of the system information.

Use the undo info-center source command to remove the specified output rules.

By default, the output rules for the system information are listed in Table 1-9.

This command can be used to configure the filter and redirection rules of log/trap/debugging information.

For example, the user can set to output log information with severity higher than warnings to the log host, and information with severity higher than informational to the log buffer. The user can also set to output trap information of the IP module to a specified output destination.

Note that:

l If you do not use the module-name argument to set output rules for a module, the module uses the default output rules or the output rules set by the default keyword; otherwise the module uses the output rules separately set for it.

l When you use the module-name argument to separately set the output rules for a module, the default output rules for the module become: Log and trap information is enabled, with severity being informational; debugging information is disabled, with severity being debugging.

l After you separately set the output rules for a module, you must use the module-name argument to modify or remove the rules. The new configuration by using the default keyword is invalid on the module.

Table 1-9 Default output rules for different output destinations

Output destination	Modules allowed	LOG		TRAP		DEBUG
Output destination	Modules allowed	Enabled/disabled	Severity	Enabled/disabled	Severity	Enabled/disabled	Severity
