Restrictions
• SNMP features in this release are read-only.
–
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.
• SNMPv1 and SNMPv2c are not secure protocols.
You cannot use a firewall to secure SNMP traffic.
•
In this release, the SNMP Notification Module does not support the SNMPv3 protocol.
Understand SNMP Concepts
Your fully licensed and equipped DMS-Admin software can use SNMPv1 or SNMPv2c to:
•
Respond to Cisco DMS MIB schema-compliant queries from your NMS.
•
Send notification messages automatically to your NMS whenever predefined system event
types occur.
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.
Our MIB schema models three object groups.
Object Group Description
DMS Systems Group Models all distributed component parts of this CiscoDMS installation as a
single, abstract system.
