Configuring email alerting

About email alerting

The email alerting feature enables sending alert emails to the specified email addresses (typically, the network administrator) when particular events occur. When an event occurs, the device generates log information. This feature collects the log information and sends it to the network administrator in an email.

The device supports sending alert emails for the following events:

·     Node failure—When a real server fails or recovers from a failure, an alert email is sent. For information about real servers, see server load balancing in Load Balancing Configuration Guide.

·     Link failure—When a link fails or recovers from a failure, an alert email is sent. For information about links, see outbound link load balancing in Load Balancing Configuration Guide.

·     Network attack—When a network attack is detected, an alert email is sent. This event type is not supported in the current software version. For information about network attack types, see attack detection and prevention configuration in Security Configuration Guide.

3.     Specify the IP address or domain name of the email server.

email-server host { domain domain-name | ip ip-address }

By default, the IP address or domain name of the email server is not specified.

If you specify a domain name, you must configure DNS to obtain the mapping between the domain name and IP address of the email server. For more information about DNS, see Layer 3—IP Services Configuration Guide.

4.     (Optional.) Specify the port number of the email server.

email-server port port

By default, the port number of the email server is 25.

5.     (Optional.) Enable client authentication.

email-server client-authentication enable

By default, client authentication is disabled.

For the email server to authenticate the device, enable client authentication.

6.     (Optional.) Configure the username and password used by the email server to authenticate the device.

email-server username username password { cipher | simple } password

By default, the username and password are not configured.

If you have enabled client authentication, you must configure the username and password.

‌

Procedure

1.     Assign IP addresses to interfaces and configure routes. Make sure the network connections are available. (Details not shown.)

2.     Configure server load balancing.

For more information, see server load balancing in Load Balancing Configuration Guide.

3.     Configure the email server:

# Create an email server and enter email server view.

<Device> system-view

[Device] email-server smtp-server1

# Specify the IPv4 address of the email server as 200.1.1.1.

[Device-email-server-smtp-server1] email-server host ip 200.1.1.1

4.     Test the email server:

# Send a test email to test the availability of the configured email server.

[Device-email-server-smtp-server1] email-server test

Email server is available.

# Return to system view.

[Device-email-server-smtp-server1] quit

5.     Configure email sending settings:

# Create and enter the email view of the warning type.

[Device] send-email type warning

# Configure the node failure event as a trigger for sending alert emails.

[Device-email-warning] event node-failure

# Specify smtp-server1 as the SMTP server for sending alert emails.

[Device-email-warning] email-server smtp-server1

# Configure the email subject as The state of real server.
