# 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.

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
 
local4.info    /var/log/Switch/information
When you edit the file "/etc/syslog.conf", note that:
A note must start in a new line, starting with a "#" sign.
In each pair, a tab should be used as a separator instead of a space.
No space is allowed at the end of a file name.
The device name (facility) and received log information severity level specified 
in the file "/etc/syslog.conf" must be the same as those corresponding 
parameters configured in the commands info-center loghost and 
info-center source. Otherwise, log information may not be output to the log 
host normally.
Step 3: After the log file "information" is created and the file "/etc/syslog.conf" is 
modified, execute the following command to send a HUP signal to the system 
daemon "syslogd", so that it can reread its configuration file "/etc/syslog.conf".
# ps -ae | grep syslogd
 
147
 
# kill -HUP 147 
After all the above operations, the switch can make records in the corresponding 
log file.
Through combined configuration of the device name (facility), information severity 
level threshold (severity), module name (filter) and the file "syslog.conf", you can 
sort information precisely for filtering.

Network requirements
The switch sends the following log information to the Linux log host whose IP 
address is 202.38.1.10: All modules’ log information, with severity higher than 
"errors".
