Configuration procedure

Before the configuration, make sure that Device and PC are reachable.

1. Configure the device

# Enable information center.

<Sysname> system-view

[Sysname] info-center enable

# Specify the host with IP address 1.2.0.1/16 as the log host. Use channel loghost to output log

information (optional, loghost by default), and use local5 as the logging facility.

[Sysname] info-center loghost 1.2.0.1 channel loghost facility local5

# Disable the output of log, trap, and debugging information of all modules on channel loghost.

[Sysname] info-center source default channel loghost debug state off log state off trap

state off

CAUTION:

Because the default system configurations for different channels are different, you need to first disable the

output of log, trap, and debugging information of all modules on the specified channel (loghost in this

example). Then configure the output rule as needed so that unnecessary information will not be output.

# Configure the information output rule. Allow log information of all modules with severity equal to or

more severe than informational to be output to the log host.

[Sysname] info-center source default channel loghost log level informational state on

2. Configure the log host

Step 1: Log in to the log host as a root user.

Step 2: Create a subdirectory named Device under directory /var/log/, and create file info.log under

the Device directory to save logs of Device.

# mkdir /var/log/Device

# touch /var/log/Device/info.log

Step 3: Edit file /etc/syslog.conf and add the following contents.

# Device configuration messages
