When developing code to interface with the iControl GSM agent, developers often ask how to determine a specific device index. A programming approach would be to poll the alarm status table using SNMP GET‑NEXT, starting at the beginning of the table, and then to compare the returned varBind value (using contains) with the Densité or Imaging frame name. Once an entry in the table is found that matches the frame name, the device index can be determined from the OID.
