Configuration procedure

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 of at least informational.

[Device] info-center source mac loghost level informational

Configure the log host, Host B:

Configure Solaris as follows. Configure other UNIX operating systems in the same way Solaris is configured.

1. Log in to the log host as a root user.

2. Create a subdirectory named Device in directory /var/log/.

   # mkdir /var/log/Device
   

3. Create file info.log in the Device directory to save logs from Device.

   # touch /var/log/Device/info.log
   

4. 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 of at least informational to the file /var/log/Device/info.log.

5. 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.

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 interface Ten-GigabitEthernet 1/0/1 to enable Ten-GigabitEthernet 1/0/1 to record MAC address change information when the interface performs either of the following operations:

• Learns a new MAC address.

• Deletes an existing MAC address.

[Device] interface ten-gigabitethernet 1/0/1
[Device-Ten-GigabitEthernet1/0/1] mac-address information enable added
[Device-Ten-GigabitEthernet1/0/1] mac-address information enable deleted
[Device-Ten-GigabitEthernet1/0/1] quit

# Set the MAC Information queue length to 100.

[Device] mac-address information queue-length 100

# Set the MAC change notification interval to 20 seconds.

[Device] mac-address information interval 20
