SNMP

SNMP (Simple Network Management Protocol) has emerged as an important standard in the broadcast industry, allowing broadcasters to monitor the equipment from multiple vendors using a single, IP‑based protocol. iControl provides SNMP support in two distinct and important ways.
iControl acts as an SNMP manager by reading the status of third party devices that support SNMP and have published their SNMP MIB (Management Information Base). It augments the status information using streaming video, audio and scope telemetry data gathered using Densité Series cards and the Allégro Streaming Encoder/Server.
In those cases where a third party SNMP management application is deployed, iControl acts as an SNMP agent reporting errors and status to the SNMP manager using the SNMP protocol and its own SNMP MIB.
For devices that do not provide IP connectivity, the iControl Application Server acts as an SNMP translator and provides SNMP Agent functionality. The Application Server receives status information from the devices using their existing protocols, and will issue SNMP TRAPS and respond to SNMP GET messages on behalf of the devices below it. The Application Server further enhances SNMP Agent capability by allowing users to create virtual alarms, which can be enabled or disabled according to a schedule, or slaved to an automation system.
 

 

NOTE: Grass Valley devices that provide IP connectivity at the frame—such as Densité and Kaleido—offer direct SNMP support, allowing third party SNMP Manager applications to get status information using an SNMP GET command.
