Configuration procedure
Before the configuration, make sure 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
# To avoid outputting unnecessary information, disable the output of log, trap, and debug
information of all modules on channel loghost.
[Sysname] info-center source default channel loghost debug state off log state off
trap state off
# 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
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.
/var/log/Device/info.log
