Configuring logs on CPE devices

Logs generated on CPE devices are stored locally or sent to an external Syslog server. When storing logs locally, you can specify a maximum size. You can specify a prefix to be assigned to logs before they are sent to the external Syslog server.

To view the local log on the CPE device, you need to request diagnostic information.

You can specify log settings in a CPE template or on the device. When you specify log settings in a CPE template, such settings are automatically propagated to all devices that are using the template.

To configure logs on CPE devices:

1. Configure logs in one of the following ways:
   • If you want to configure logs in a CPE template, go to the SD-WAN → CPE templates menu section, click the template and in the displayed settings area, select the Log files tab.
   • If you want to configure logs on a CPE device, go to the SD-WAN → CPE menu section, click the device, and in the displayed settings area, select the Log files tab and select the Override check box.

   The log settings are displayed.

2. In the Log files size (KB) field, enter the size of the logs on the CPE device in kilobytes. Range of values: 64 to 2048. The default setting is 64. If the maximum log size is exceeded, new logs overwrite the oldest logs.
3. If you want the CPE device to send logs to an external Syslog server, specify the Syslog server:
   1. In the Syslog server IP/FQDN field, enter the IP address of the Syslog server.
   2. In the Syslog server port field, enter the port number of the Syslog server. Range of values: 0 to 65,353.
   3. In the Syslog server protocol drop-down list, select the protocol for sending logs to the Syslog server:
      • UDP (default)
      • TCP
   4. In the Log files prefix field, enter the prefix that you want the CPE device to assign to the logs. Maximum length: 256 characters.
4. In the upper part of the settings area, click Save to save the settings of the CPE template or device.
