channel-number: Displays information of the channel with a specified number, where channel-number represents the channel number, in the range 0 to 9.

channel-name: Displays information of the channel with a specified name, where channel-name represents the channel name, which could be a default name or a self-defined name. The user needs to specify a channel name first before using it as a self-defined channel name. For more information, see the info-center channel name command.

Parameters

interface-type interface-number: Specifies a source interface by its type and number.

Description

Use the info-center loghost source command to specify the source IP address for log information.

Use the undo info-center loghost source command to restore the default.

By default, the interface for sending log information is determined by the matched route, and the primary IP address of this interface is the source IP address of the log information.

After the source IP address of log information is specified, no matter the log information is actually output through which physical interface, the source IP address of the log information is the primary IP address of the specified interface. If you want to display the source IP address in the log information, you can configure it by using this command.

Note that:

l          The info-center loghost source command takes effect only after the information center is enabled with the info-center enable command.

l          The IP address of the specified source interface must be configured; otherwise, although the info-center loghost source command can be configured successfully, the log host will not receive any log information.

Examples

By default, the log information in the following format is displayed on the log host:

<188>Jul 22 05:58:06 2008 Sysname %%10IFNET/4/LINK UPDOWN(l):   Vlan-interface1: link status is UP

# Configure the interface VLAN-interface 1 as the source interface to output log information to the log host.

<Sysname> system-view

[Sysname] info-center loghost source vlan-interface 1

After the above configuration, the log information in the following format is displayed on the log host (compared with the default format, the following format has the -DevIP=2.2.2.2 field):

View

System view

Default Level

2: System level

Parameters

module-name: Specifies the output rules of the system information of the specified modules. For instance, if information on ARP module is to be output, you can configure this argument as ARP. You can use the info-center source ? command to view the modules supported by the AP.

default: Specifies the output rules of the system information of all the modules allowed to output the system information, including all the modules displayed by using the info-center source ? command.

debug: Debugging information.

log: Log information.

trap: Trap information.

level severity: Specifies the severity of system information, see Table 1-4 for details. With this keyword, you can specify the severity level of the information allowed/denied to output.

state state: Configures whether to output the system information, which could be on (enabled) or off (disabled). With this keyword, you can specify whether to output the specified system information.

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

channel-name: Specifies a channel name, which could be a default name or a self-defined name. The user needs to specify a channel name first before using it as a self-defined channel name. For more information, see the info-center channel name command.

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 1-8.

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

For example, the user can set to output log information with severity higher than warning 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          If you use the default keyword to set the output rules, the default output rules for the modules are used. see Table 1-8 for details.

l          If you use the module-name argument to set the output rules for a module without specifying the debug, log, and trap keywords, the default output rules for the module are as follows: the output of log and trap information is enabled, with severity being informational; the output of debugging information is disabled, with severity being debug. For example, if you execute the command info-center source snmp channel 5, the command is actually equal to the command info-center source snmp channel 5 debug level debugging state off log level informational state on trap level informational state on.

l          If you repeatedly use the command to set the output rules for a module or for all the modules with the default keyword, the last configured output rules take effect

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.

l          You can configure to output the log, trap and debugging information to the trap buffer, but the trap buffer only receives the trap information and discards the log and debugging information.

l          You can configure to output the log, trap and debugging information to the log buffer, but the log buffer only receives the log and debugging information and discards the trap information.

l          You can configure to output the log, trap and debugging information to the SNMP module, but the SNMP module only receives the trap information and discards the log and debugging information.

Table 1-8 Default output rules for different output destinations

Output destination	Modules allowed	LOG		TRAP		DEBUG
