The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

DMS-Admin supports email (SMTP) natively.
In addition, you can purchase and install a license key to activate our SNMP Notifications Module. After you activate this module, you can start to use:
In this framework, you can define alarms that associate system events with methods to deliver notification messages.
Timesaver The Alerts gauge at Administration > Dashboard shows the total count of notification messages delivered in the past 1 hour. Click View Alerts to jump directly to the Alerts page.
– Your NMS can use SNMP to submit queries to DMS-Admin but cannot use SNMP to edit the configuration of any Cisco DMS component.
– You cannot edit the (default) community string of your DMM appliance.
Your fully licensed and equipped DMS-Admin software can use SNMPv1 or SNMPv2c to:
Any dedicated NMS that supports SNMP can load CISCO-DIGITAL-MEDIA-SYSTEMS-MIB.my into its MIB browser. CiscoWorks is one example. Your NMS can then send SNMP queries to DMS-Admin and represent its responses correctly to monitor objects from our MIB schema.
Our MIB schema models three object groups.
An address conflict occurs when a DHCP server assigns to one registered DMP the exact dynamic IP address that some other registered DMP used previously.

Activates automatic delivery of email notification messages for all corresponding event types.
Activates automatic delivery of SNMPv2c notification messages to your NMS for all corresponding event types.
Activates automatic delivery of notification messages to your Syslog collector.
You can enable or disable the email service (SMTP) on your DMM appliance. When this service is enabled, DMS-Admin can send email notifications automatically to you or other interested parties whenever system events of predefined types occur.
Step 2 Choose Settings > External Servers > SMTP.
Step 3 Enter the required values to start or stop email service on your DMM appliance.
You must enter these values or you cannot send notification messages:
Step 5 Stop. You have completed this procedure.
Cisco DMS can convey its notifications to an external SNMP server.
Step 2 Choose Settings > SNMP.
Step 3 Click the Server Status radio button to enable or disable SNMP monitoring.
Step 4 Enter in the Host field the routable IP address or DNS-resolvable hostname of your NMS.
Step 5 Enter in the Port field the numeric UDP port assignment reserved for SNMP traffic.
Step 6 Apply the community string.
Step 7 Enter in the Community String field the password to identify that community.
Tip The default Community String value is public.
Step 9 Stop. You have completed this procedure.
Step 1 Log in to your Cisco.com account on ftp.cisco.com.
Timesaver Alternatively, go to http://cisco.com/go/dms/mib.
Step 4 Load both files into your network management system (NMS).
Tip Manufacturer documentation for your NMS should tell you how to do this.
Step 5 When your NMS prompts you to enter the SNMP port number for your DMM appliance, use the port number :161.
Step 6 Stop. You have completed this procedure.
Step 4 Click the radio button to choose a monitoring mode.
Step 5 Choose the range of dates.
Step 6 Choose a n event type from the Type list, and then click Apply .
Step 8 Stop. You have completed this procedure.

Step 2 Choose Alerts > Notification Rules.
Step 3 Check the check boxes to turn On one or more notification methods for each listed event type.
Uncheck every check box for an event type to stop its delivery of notication messages through any medium or channel.
Step 4 (Optional) Did you check Email?
If so, you activated the Recipent field, which is now editable. Enter the email address that should receive notification messages.
Note Enter only one email address in this field. It rejects any entry that contains multiple email addresses (CSCts96411).
Tip You can enter a unique recipient address for each notification rule.
Step 6 Stop. You have completed this procedure.
Q. What might interfere with the delivery of configured email notifications for events that the Alert Browser shows?
Explanation This might happen when DMM cannot connect to your SMTP server — due to either a misconfiguration or a service outage (SMTP error 421). To determine the cause, get copies of your DMM system logs from AAI and inspect /var/log/dms/EmsService.log file.
Recommended Action Make sure the SMTP server configuration is correct in DMS-Admin. If the configuration is correct, test with a different mail server.
Q. Which SNMP versions does the MIB support?
The MIB supports SNMPv1 and SNMPv2 in this release.
Note This release does not support SNMPv3.
Q. If multiple DMPs become unreachable at the same time, will I receive separate SNMP notifications for each?
Maybe. This can occur when you configure DMS-Admin to send SNMP notifications for unreachable DMPs.
Note This release does not support notification throttling.
Q. Where can I download the MIB and its agent capabilities file?
Log in to your Cisco.com account and go to ftp://ftp.cisco.com/pub/mibs/v2/. Alternatively, go to http://cisco.com/go/dms/mib.
Q. Which object groups does the MIB support?
To understand these object groups, see the agent capabilities file.
Q. Can I configure the community for my SNMP agent to accept ‘get’ requests?
Yes, from the public community.
Q. Can I configure the community for my SNMP agent to accept ‘set’ requests?
Q. Can I configure the community for my external SNMP server, which receives traps?
