[Sysname] info-center source default channel console debug state off log state off trap
state off
To avoid output of unnecessary information, disable the output of log, trap, and debug information of all
modules on the specified channel (console in this example), and then configure the output rule as
needed.
# Configure an output rule to enable the ARP and IP modules to send log information that has a severity
level of at least informational to the console. (The supported source modules depend on the device
model.)
[Sysname] info-center source arp channel console log level informational state on
[Sysname] info-center source ip channel console log level informational state on
[Sysname] quit
# Enable the display of log information on the console. By default, the display of log information on the
console is enabled.
<Sysname> terminal monitor
Info: Current terminal monitor is on.
<Sysname> terminal logging
Info: Current terminal logging is on.
Now, if the ARP and IP modules generate log information, the information center automatically sends the
log information to the console.

Configuration procedure
Before the configuration, make sure the device and the log host can reach each other. (Details not
shown.)

Configure the device:
# Enable the information center.
<Device> system-view
[Device] info-center enable
# Specify the log host 1.2.0.1/16, use channel loghost to output log information, and specify
local4 as the logging facility. By default, log information is output to a log host through channel
loghost.
[Device] info-center loghost 1.2.0.1 channel loghost facility local4
# Disable the output of log, trap, and debug information of all modules on channel loghost.
