Mail Notification

1. Function Overview

The mail notification function sends mail notifications of information detected by the L2MS function or terminal monitoring function.
By specifying the following settings, mail notifications can be sent with information detected by various functions.

  • Specify settings for the mail server used to send mails.

  • Specify the mail template.

2. Definition of Terms Used

Mail Template

The mail template defines the collection of information needed for sending mail.

  • Mail server to use

  • Sender mail address

  • Recipient mail address

  • Subject of mail

  • Notification content

  • Transmission wait time

3. Function Details

3.1. Action

After mail server settings and mail template settings have been configured correctly, the mail notification function will enter the send-standby state whenever a notification event occurs for a function that supports mail notification.
When the mail notification function is in the send-standby state, the function will wait until the specified mail transmission wait time specified in each mail template elapses.
When the mail transmission wait time has elapsed, the mail notification function combines the information for notification events that occurred during the wait time into a single mail and sends it to the recipient.

3.2. Mail server settings

Settings can be specified in the List of Registered Mail Servers displayed by clicking [Detailed settings] - [mail notification] in the web GUI.
To display the Mail server settings, click the New button or the Setting button for existing settings.
In Mail server settings, make the following settings.

  • Account identification name
    Name for uniquely identifying the mail server settings. This setting may be omitted.

  • SMTP server address

  • SMTP server port number

  • Encrypting SMTP
    Selects either “SMTP over SSL” or “STARTTLS” as the encryption method.

  • SMTP authentication
    To use SMTP authentication, enter the username and password.

3.3. Specify the mail template

Mail template settings can be specified by clicking [Detailed settings] - [mail notification] in the web GUI to display the List of mail notification settings.
Press the New button or the Setting button for an existing setting to display mail notification settings.
In mail notification settings, specify the following settings.

  • Source (From)

  • Destination (To)

  • Subject
    If the Use default subject box is checked, then the mail subject will always be in the form Notification from (device name).

  • Notification content
    Error types can be specified in detail for LAN map error detection, so that only the specified type of notifications are output.

  • Mail transmission wait time

5. Points of Caution

The following are precautions related to SMTP authentication.

  • The SMTP authentication only supports the LOGIN method.

  • PLAIN, CRAM-MD5, and other methods are not supported.

Precautions for using firmware not compatible with the mail notification function.

  • If the firmware is updated from a version that does not support a command to a version that does support the command, commands specified in the web GUI are directly carried over as command settings.

  • To revert to the firmware version that does not support the commands, any changes to settings made using the firmware that does support the commands are not migrated and must be specified again after restoring the older version.

  • If no settings were changed, then the current settings can be maintained.

The following are precautions related to LAN map error detection.

  • Errors are indicated in notifications as active until the error is resolved, even if the error notification is disabled without resolving the error.

  • Specifically, even after a notification is disabled, an mail is sent after the error is resolved and is included in mails about the occurrence of other errors.
