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 

information to the log host channels by default. 

[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 

2)  Configure the log host: 

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

operation systems are similar. 

Step 1: Execute the following commands as the super user (root user). 

# 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. 

# Switch configuration messages
