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.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.
Our MIB schema models three object groups.
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.
