Configuration procedure Before the configuration, make sure that the device and the log host can reach each other. 1. Configure the device: # Enable the information center. system-view [Sysname] info-center enable # Specify the host 1.2.0.1/16 as the log host. Use channel loghost to output log information (optional, loghost by default), and use local4 as the logging facility. [Sysname] info-center loghost 1.2.0.1 channel loghost facility local4 # Disable the output of log, trap, and debugging information of all modules on channel loghost. [Sysname] info-center source default channel loghost debug state off log state off trap state off To avoid outputting unnecessary information, disable the output of log, trap, and debugging information on the specified channel (loghost in this example) before you configure an output rule. # Configure an output rule to output to the log host ARP and IP log information that has a severity level of at least informational. (The source modules that are allowed to output information depend on the switch model.) [Sysname] info-center source arp channel loghost log level informational state on [Sysname] info-center source ip channel loghost log level informational state on 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. a. Log in to the log host as a root user. b. Create a subdirectory named Device in directory /var/log/, and then create file info.log in the Device directory to save logs from Device. # mkdir /var/log/Device # touch /var/log/Device/info.log c. Edit the file /etc/syslog.conf and add the following contents. # Device configuration messages local4.info /var/log/Device/info.log In this configuration, local4 is the name of the logging facility that the log host uses to receive logs. info is the information level. The UNIX system records the log information that has a severity of at least informational to the file /var/log/Device/info.log. NOTE: Be aware of the following issues while editing the file /etc/syslog.conf: • Comments must be on a separate line and must begin with a pound sign (#). • No redundant spaces are allowed after the file name. • The logging facility name and the information level specified in the /etc/syslog.conf file must be identical to those configured on the device by using the info-center loghost and info-center source commands. Otherwise the log information might not be output properly to the log host. d. Display the process ID of syslogd, kill the syslogd process and then restart syslogd by using the -r option to make the modified configuration take effect. # ps -ae | grep syslogd 48

Configuration procedure
Before the configuration, make sure that the device and the log host can reach each other.
1.
Configure the device:
# Enable the information center.
<Sysname> system-view
[Sysname] info-center enable
# Specify the host 1.2.0.1/16 as the log host. Use channel
loghost
to output log information
(optional,
loghost
by default), and use
local4
as the logging facility.
[Sysname] info-center loghost 1.2.0.1 channel loghost facility local4
# Disable the output of log, trap, and debugging information of all modules on channel
loghost
.
[Sysname] info-center source default channel loghost debug state off log state off
trap state off
To avoid outputting unnecessary information, disable the output of log, trap, and debugging
information on the specified channel (
loghost
in this example) before you configure an output rule.
# Configure an output rule to output to the log host ARP and IP log information that has a severity
level of at least
informational
. (The source modules that are allowed to output information depend
on the switch model.)
[Sysname] info-center source arp channel loghost log level informational state on
[Sysname] info-center source ip channel loghost log level informational state on
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.
a.
Log in to the log host as a root user.
b.
Create a subdirectory named
Device
in directory
/var/log/
, and then create file
info.log
in the
Device
directory to save logs from
Device
.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
c.
Edit the file
/etc/syslog.conf
and add the following contents.
# Device configuration messages
local4.info
/var/log/Device/info.log
In this configuration,
local4
is the name of the logging facility that the log host uses to receive logs.
info
is the information level. The UNIX system records the log information that has a severity of at least
informational
to the file
/var/log/Device/info.log
.
NOTE:
Be aware of the following issues while editing the file
/etc/syslog.conf
:
•
Comments must be on a separate line and must begin with a pound sign (#).
•
No redundant spaces are allowed after the file name.
•
The logging facility name and the information level specified in the
/etc/syslog.conf
file must be
identical to those configured on the device by using the
info
-
center loghost
and
info-center source
commands. Otherwise the log information might not be output properly to the log host.
d.
Display the process ID of
syslogd
, kill the
syslogd
process and then restart
syslogd
by using the
–r
option to make the modified configuration take effect.
# ps -ae | grep syslogd
