Configuration restrictions and guidelines
When you edit the file /etc/syslog.conf, follow these restrictions and guidelines:
• Comments must be on a separate line and must begin with a pound sign (#).
• No redundant spaces are allowed after the file name.
• The logging facility name and the severity level specified in the /etc/syslog.conf file must be the
same as those configured on the device. Otherwise, the log information might not be output
correctly to the log host. The logging facility name and the severity level are configured by using the
info-center loghost and info-center source commands, respectively.
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:
Configure Solaris as follows. Configure other UNIX operating systems in the same way Solaris is
configured.
a. Log in to the log host as a root user.
b. Create a subdirectory named Device in directory /var/log/.
# mkdir /var/log/Device
