Chapter 8 Events and Notifications

Concepts

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.myinto 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.

Our MIB schema models three object groups.

Object Group	Description
DMS Systems Group	Models all distributed component parts of this Cisco DMS installation as a
	single, abstract system.
DMS Features Group	Categorizes licensed and unlicensed features.
DMS Inventory Group	Lists the devices that constitute your Cisco DMS installation and describes
	their operational status.

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.
