Now, if the ARP and IP modules generate log information, the information center automatically sends the
log information to the console.
Outputting log information to a UNIX log host
Network requirements
Configure the router to send ARP and IP log information that has a severity level of at least informational
to the UNIX log host at 1.2.0.1/16.

Configuration procedure
Before the configuration, make sure the router and the log host can reach each other. (Details not shown.)
1. Configure the router:
# Enable the information center.
<Sysname> system-view
[Sysname] info-center enable
# Specify the log host 1.2.0.1/16, use channel loghost to output log information (optional,
loghost by default), and specify local4 as the logging facility.
[Sysname] info-center loghost 1.2.0.1 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 off
To avoid outputting unnecessary information, disable the output of log, trap, and debugging
information on the specified channel (loghost in this example) before you configure an output rule.
# Configure an output rule to output to the log host ARP and IP log information that has a severity
level of at least informational.
[Sysname] info-center source arp channel loghost log level informational state on trap
state off
[Sysname] info-center source ip channel loghost log level informational state on trap
state off
2. Configure the log host:
The following configurations were performed on Solaris which has similar configurations to the
UNIX operating systems implemented by other vendors.
a. Log in to the log host as a root user.
b. Create a subdirectory named Router in directory /var/log/, and then create file info.log in
the Router directory to save logs from the router.
# mkdir /var/log/Router
# touch /var/log/Router/info.log
c. Edit the file syslog.conf in directory /etc/ and add the following contents.
# Router configuration messages
local4.info /var/log/Router/info.log
