Device Index

512

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
alarm table using an SNMP MIB browser loaded with the MIRANDA-MIB and the GSM-MIB
definitions. You can do this by using iC Navigator’s integrated MIB Browser.

Figure 8-124: Viewing device index values using iC Navigator’s integrated MIB Browser

Devices are distinguished based on the host name of the Application Server and either the
Densité frame name, or the Imaging frame ID and com port. If these settings are not changed,
the device index will not change, even if the system is rebooted or restarted.

The index will change if one of the following occurs:

• a Densité frame name changes

• an Application Server host name (or IP address, if there is no DNS) changes

• the RS422 ID of an Imaging frame changes

• an Imaging frame’s serial (com) port connection to the Application Server changes
