Alerts and notifications

Introduction

The Digi CM unit can be configured for system alerts and notifications. It sends email messages
when the number of system log messages reaches a certain value or when an alarm message is
detected in the serial port data. The Digi CM unit uses SMTP (Simple Mail Transfer Protocol) for
sending the notifications. To use SMTP, the system administrator must configure a valid SMTP
server for sending the emails. The Digi CM unit supports three types of SMTP servers: SMTP server
without authentication, SMTP server with authentication, and POP before SMTP.
The Digi CM unit also supports SNMP (Simple Network Management Protocol), a protocol used to
manage a network and monitor devices on a network. System and port alerts can also be sent using
SNMP traps. The Digi CM unit supports both versions 1 and 2 of the SNMP protocol. The main
function of SNMP on the Digi CM unit is to allow a system administrator to query remote devices for
information.

Configuring SMTP alerts

Most SMTP servers check the sender's email address with the host domain name to verify the
address as authentic. Consequently, when assigning an email address for the device email address,
any arbitrary username with the registered hostname may be used. An example is
username@company.com.
To configure the Digi CM unit for SMTP alerts, the following parameters are required:
SMTP server - Use either the hostname or the IP address.
Device mail address - Specify the sender's email address for the log and alarm delivery.
SMTP mode - Specify the type of SMTP server to use.
Username and password - These fields are required for POP before SMTP and SMTP with
authentication servers.
To configure SMTP alerts on the Digi CM unit, do the following:
1 Access the web interface.
2 Under the Network heading, choose SMTP configuration.
