address changes in syslog messages to the log host, Host B, of the interface.
Figure 6 Network diagram
Configuration procedure
1. Configure Device to send syslog messages to Host B:
# Enable the information center.
system-view
[Device] info-center enable
# Specify the log host 192.168.1.2/24 and specify local4 as the logging facility.
[Device] info-center loghost 192.168.1.2 facility local4
# Disable log output to the log host.
[Device] info-center source default loghost deny
To avoid output of unnecessary information, disable all modules from outputting logs to the
specified destination (loghost, in this example) before you configure an output rule.
# Configure an output rule to output to the log host MAC address logs that have a severity level of
at least informational.
[Device] info-center source mac loghost level informational
2. Configure the log host, Host B:
The following configurations were performed on Solaris. Other UNIX operating systems have
similar configurations.
a. Log in to the log host as a root user.
b. Create a subdirectory named Device in directory /var/log/, and then create file info.log in the
Device directory to save logs from Device.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
c. Edit the file syslog.conf in directory /etc/ and add the following contents:
