Configuration procedure
1) Configure the switch:
# Enable the information center.
<Switch> system-view
[Switch] info-center enable
# Disable the function of outputting information to log host channels, because all modules output log

[Switch] undo info-center source default channel loghost
# Configure the host whose IP address is 202.38.1.10 as the log host. Permit ARP and IP modules to
output information with severity level higher than informational to the log host.
[Switch] info-center loghost 202.38.1.10 facility local4
[Switch] info-center source arp channel loghost log level informational debug state off trap
state off
[Switch] info-center source ip channel loghost log level informational debug state off trap
state off

The operations here are performed on SunOS 4.0. The operations on other manufacturers' Unix
operation systems are similar.

# mkdir /var/log/Switch
# touch /var/log/Switch/information
Step 2: Edit the file “/etc/syslog.conf” as the super user (root user) to add the following selector/action
pairs.
