# 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 specify
local4
as the
logging facility.

the channel

c
CAUTION:
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.
[Sysname] info-center source arp channel loghost log level informational state on
[Sysname] info-center source ip channel loghost log level informational state on

Configuring 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: Issue the following commands as a root user.
# mkdir /var/log/MyDevice
# touch /var/log/MyDevice/information
Step 2: Edit the file /etc/syslog.conf as a root user and add the following
selector/action pair.
# MyDevice configuration messages
local4.info
/var/log/MyDevice/information
n
Be aware of the following issues while editing the /etc/syslog.conf file
■
Comments must be on a separate line and must begin with the # sign.
■
The selector/action pair must be separated with a tab key, rather than a space.
■
No redundant spaces are allowed in the file name.
■
The device name and the accepted severity of log information specified by the
/etc/syslog.conf file must be identical to those configured on the device using
the
info
-
center loghost
or
info-center source
command; otherwise the log
information may not be output properly to the log host.
Step three: After the log file information has been created and the configuration
file /etc/syslog.conf has been modified, ensure that the configuration file
/etc/syslog.conf is reread:
