Description

Use the info-center source command to specify the information source in the information center and the output direction.

Use the undo info-center source command to cancel the configuration of information source and output direction.

This command can be used for filtering of log, trap or debugging information. For example, it can control information output from the IP module to any direction. You can configure to output information with severity higher than “warning” to the log host, and information with severity higher than “informational” to the log buffer. You can also configure to output trap information to the log host at the same time.

The info-center source command determines the output direction according to channel name or channel number. Each output direction is assigned with a default information channel at present, as shown in Table 1-3.

Table 1-3 Default information channel

Output direction	Information channel name
Console	console
Monitor terminal	monitor
Log host	loghost
Log buffer	logbuffer
Trap buffer	trapbuffer
SNMP	snmpagent

Each information channel is configured with a default record, whose module name is default and module number is 0xffff0000. In the record, the default settings for log, trap and debugging information may differ with channels. If no record is configured for a channel, this default record is adopted.

# Configure to output the log information of the VLAN module on the SNMP channel, and only output the log information above the “emergencies” severity.

1.1.15 info-center synchronous

Syntax

info-center synchronous

undo info-center synchronous

View

System view

Parameter

None

Description

Use the info-center synchronous command to enable synchronous terminal output, so that if system information (such as log information) is output when the user is inputting information, the command prompt and input information are echoed after the output (note that, the command prompt is echoed in command edit state but is not echoed in interactive state).

Use the undo info-center synchronous command to disable synchronous terminal output.

By default, the synchronous terminal output function is disabled.

& Note:

l By enabling the synchronous terminal output function with the info-center synchronous command, you can avoid users’ input from being interrupted by system information output.

l Running the info-center synchronous command during debugging information collection may result in a command prompt echoed after each item of debugging information. To avoid unnecessary output, it is recommended to disable synchronous terminal output in such cases.

Example

# Enable synchronous terminal output.

1.1.16 info-center switch-on

Syntax

info-center switch-on { unit unit-id | master | all } [ debugging | logging | trapping ]*

undo info-center switch-on { unit unit-id | master | all } [ debugging | logging | trapping ]*

View

System view

Parameter

unit unit-id: Specifies a switch on which information output function is to be enabled/disabled.

master: Controls the switch that serves as master.

all: Controls all switches within the fabric.

debugging: Enables the debugging information output source.

logging: Enables the log information output source.

trapping: Enables the trap information output source.

Description

Use the info-center switch-on command to enable information output function for a specified switch in a fabric.

Use the undo info-center switch-on command to disable the corresponding information output function for a switch.

By default, debugging information output is enabled and log and trap information output is disabled for the master switch in the fabric. Debugging, log and trap information output for other switches is disabled in the fabric.

After the switches supporting IRF form a fabric, the log, debugging and trap information of each switch in the fabric can be synchronized. Each switch sends its own information to other switches in the fabric and receives information sent by other switches at the same time to update the information on itself. In this way, the switch ensures the synchronization of log, debugging and trap information in the whole fabric.

The switch provides command lines to enable or disable information output for each switch. If you disable information output for a switch, the switch will no longer send information to other switches, but still receive information sent by other switches.

You can enable or disable a specified type of information output for a specified switch as required.

Example

# Enable trap information output for the switch whose Unit ID is 2 in the fabric.
