Information Center Configuration Examples
Outputting Log Information to a Unix Log Host
Network requirements
z
Send log information to a Unix log host with an IP address of 1.2.0.1/16;
z
Log information with severity higher than informational will be output to the log host;
z
The source modules are ARP and IP.

Configuration procedure
Before the configuration, make sure that there is a route between Device and PC.
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 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
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
2) 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.
