# Specify the host with IP address 184.108.40.206/16 as the log host, use channel loghost to output log
information (optional, loghost by default), and use local4 as the logging facility.
[Sysname] info-center loghost 220.127.116.11 channel loghost facility local4
# 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
As the default system configurations for different channels are different, you need to disable the output
of log, trap, and debugging information of all modules on the specified channel (loghost in this example)
first and then configure the output rule as needed so that unnecessary information will not be output.
# Configure the information output rule: allow log information of ARP and IP modules with severity equal
to or higher than informational to be output to the log host. (Note that the source modules allowed to
output information depend on the device model.)
[Sysname] info-center source arp channel loghost log level informational state on
[Sysname] info-center source ip channel loghost log level informational state on
Configure the log host
The following configurations were performed on SunOS 4.0 which has similar configurations to the Unix
operating systems implemented by other vendors.
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
In the above configuration, local4 is the name of the logging facility used by the log host to receive logs.
info is the information level. The Unix system will record the log information with severity level equal to
or higher than informational to file /var/log/Device/info.log.
