Overview
DMS-Admin supports email (SMTP) natively.
In addition, you can purchase and install a license key to activate the SNMP Notifications Module . After you activate this module, you can start to use:
- A network management MIB file called CISCO-DIGITAL-MEDIA-SYSTEMS-MIB.my .
- The agent capabilities file that describes which MIB objects we support in this release.
In this framework, you can define alarms that associate system events with methods to deliver notification messages.

Restrictions
–
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.
Understand SNMP Concepts
Your fully licensed and equipped DMS-Admin software can use SNMPv1 or SNMPv2c to:
Understand MIB and NMS Concepts
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.
- Cisco DMS server appliances.
- Cisco DMPs — in the sense that, when your DMPs report their events to your DMM appliance, it forwards the appropriate SNMP alerts .
- Cisco Digital Media Manager software.
- Cisco Show and Share software.
Understand IP Address Conflict Events
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.
When the DMP that previously used the address is no longer in active use, you should delete the record of it in Digital Signs .
When the DMP that previously used the address is one that should remain active, confirm that it is still running and still connected to the network, then restart it and confirm that its DHCP server does not assign IP addresses with expiration dates.

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.
Procedures
Enable or Disable Email
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.
To see and use the Settings tab, you must be logged in as an administrator.
Step 1
Choose Settings > External Servers > SMTP .
Step 2
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:
Click the radio button to enable or disable the email service.
The number to identify which TCP port is reserved for SMTP traffic.
Step 4
Stop. You have completed this procedure.
Configure SNMP Server Settings for Your DMM Appliance
Cisco DMS can convey its notifications to an external SNMP server.
Step 1
Choose Settings > SNMP .
Step 2
Click the Server Status radio button to enable or disable SNMP monitoring.
Step 3
Enter in the Host field the routable IP address or DNS-resolvable hostname of your NMS.
Step 4
Enter in the Port field the numeric UDP port assignment reserved for SNMP traffic.
Step 5
Apply the community string.
Step 6
Enter in the Community String field the password to identify that community.

Tip The default Community String value is public.
Populate the MIB Browser in Your NMS
Step 1

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 .
Define Alert Report Parameters
Step 2
Click Alert Reports , .
Step 3
Click the radio button to choose a monitoring mode.
Step 4
Choose the range of dates.
Step 5
Choose a n event type from the Type list, and then click Apply .
Define Notification Rules
- Before you can deliver notification messages to any email recipent, you must configure SMTP and enable notification operations for it.
- Before you can deliver notification messages to any NMS, you must purchase and install a license key that activates the SNMP Notification Module. Then, you must configure SNMP and enable both notification operations and query operations for it.
- Before you can deliver notification messages to any Syslog collector, you must configure Syslog and enable notification operations for it.
Step 1
Choose Alerts > Notification Rules .
Step 2
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 3
( 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.

SMTP FAQs
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.
SNMP and MIB FAQs
Q. Which SNMP versions does the MIB support?
![]()
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.
