Alarm status table generated by a GSM SNMP agent
The alarm status table (statusTable) is composed of alarm entries (statusEntry) which are
categorized by device index (deviceIndex), slot index (slotIndex) and status type index
(trapIndex)
• The device index is a unique number attributed to each Imaging or Densité frame the first
time it is discovered by the GSM.
• The slot index corresponds to the physical slot containing a card.
• The trap index maps to a type of alarm such as freeze detect or black detect.
The different alarm types available for all Grass Valley Imaging and Densité Cards are
enumerated in the MIRANDA-MIB file.
The table also contains the type, the name and the status of each alarm.
• The type field corresponds to the long ID of a card. This is a unique identifier made up of a
device identifier (Application Server host name, Densité frame name, or COM port number
for Imaging frames) plus the slot number and the card model number.
• The name field contains a human readable label for the alarm name.
• The status field contains the status of the alarm.
Device Index
The iControl GSM uses auto-discovery to find the Grass Valley Densité and Imaging frames
present in the system. These devices may originate from the Application Server where the
GSM is running, or from other Application Servers that the GSM has discovered.
The GSM SNMP agent arbitrarily allocates a unique device index to each device the first time it
is discovered. The device index starts at 1, and increments by one for each newly-discovered
device.
There is no way to know ahead of time the device index for a given Densité or Imaging frame.
The only way to determine the device index for a specific frame is to browse the GSM SNMP
