Configuration Procedure - H3C S5560S-EI Series Configuration Manual

correctly to the log host. The logging facility name and the severity level are configured by using
the info-center loghost and info-center source commands, respectively.

Configuration procedure

1.
Configure Device to send syslog messages to Host B:
# Enable the information center.
<Device> system-view
[Device] info-center enable
# Specify the log host 192.168.1.2/24 and specify local4 as the logging facility.
[Device] info-center loghost 192.168.1.2 facility local4
# Disable log output to the log host.
[Device] info-center source default loghost deny
To avoid output of unnecessary information, disable all modules from outputting logs to the
specified destination (loghost, in this example) before you configure an output rule.
# Configure an output rule to output to the log host MAC address logs that have a severity level
no lower than informational.
[Device] info-center source mac loghost level informational
2.
Configure the log host, Host B:
Configure Solaris as follows. Configure other UNIX operating systems in the same way Solaris
is configured.
a. Log in to the log host as a root user.
b. Create a subdirectory named Device in directory /var/log/.
# mkdir /var/log/Device
c. Create file info.log in the Device directory to save logs from Device.
# touch /var/log/Device/info.log
d. Edit the file syslog.conf in directory /etc/ 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, and info is the informational level. The UNIX system records the log
information that has a severity level no lower than informational to the file
/var/log/Device/info.log.
e. Display the process ID of syslogd, end the syslogd process, and then restart syslogd
using the –r option to make the new configuration take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
The device can output MAC address logs to the log host, which stores the logs to the specified
file.
3.
Enable MAC Information on Device:
# Enable MAC Information globally.
[Device] mac-address information enable
# Configure the MAC Information mode as syslog.
[Device] mac-address information mode syslog
# Enable MAC Information on GigabitEthernet 1/0/1 to enable the port to record MAC address
change information when the interface performs either of the following operations:
