[Sysname] info-center enable
# Specify the host with IP address 1.2.0.1/16 as the log host, use channel

to output log
information (optional,
loghost
by default), and use
local4
as the logging facility.

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.)

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.
Step 2: Create a subdirectory named
Device
under directory
/var/log/
, and create file
info.log
under
the
Device
directory to save logs of
Device
.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
Step 3: Edit file
/etc/syslog.conf
and add the following contents.
# Device configuration messages
local4.info /var/log/Device/info.log
In the above configuration,
local4
is the name of the logging facility used by the log host to receive
logs.
info
is the information level. The Unix system will record the log information with severity level
equal to or higher than
informational
to file
/var/log/Device/info.log
.
