DFM email notification setup

Hi All,

I have LMS 2.6 and DFM 2.0.10, configured email notification for one Subscription "INL" as sender address to
Recently I have configured another Subscription "POY" for another bunch of devices as sender "" only to

I am receiving mails to but not to

Can someone look into this issue and tell me what needs to be done.




Re: DFM email notification setup


First thing I'd check is if you are generating alarms for "POY" in the Alerts and Activities. If they are present then I'd verify I can send email to from the LMS server. If you can then we will need to examine some files.

You can start troubleshooting by verifying the configuration of your second group.

Creating a Notification Subscription

To create a notification subscription, perform the following steps:

1.  If you want to monitor a specific set of events, create an event set that contains the events you want to monitor. Otherwise, all events and alerts will be monitored.
2.  Create a notification group that specifies the criteria DFM should use when generating notifications:

  • One or more event sets (if no event set is specified, all events and alerts are monitored)
  • Devices, alert severity and status, and event severity and status

You can specify the notification group name, along with entering identifying information (using the Customer ID and Customer Revision fields).
3.  Create a subscription by doing the following:
    a.  Select the notification type (SNMP Trap, E-Mail, or Syslog).
    b.  Name the subscription and apply a notification group to it.
    c.  Specify the recipients (hostname, e-mail address).
    d.  Save the subscription. It will automatically start running.

Troubleshooting SMTP

From the LMS server, telnet to your SMTP server on TCP port 25, and make sure you can:

1.  Connect to the server

2.  Issue the following command:


Where IP is the IP address of the LMS server. The mailserver should grant you access to send email.

If that works, start a sniffer trace filtering on all tcp/25 traffic between the LMS server and the SMTP server. Generate new DFM events which should trigger email notifications, then check the sniffer trace to see what is happening.

Re: DFM email notification setup


I have been trying to generate alerts for down switches. I have performed all the notification subscription steps, but for some reason, alerts are not generated when I take down a switch via reload. Is there something I am missing? I can’t seem to find how else to configure the alert for an unresponsive switch.

Thanks for your help



Re: DFM email notification setup


Instead of a reload have you tried shutting an interface that is being actively monitored?
