DeviceHostname
This parameter is only valid for an Ethernet device and can have multiple meanings:
l
If the "deviceModel" specifies an Ethernet device, then the "deviceHostname" identifies
the device to be updated. If the "deviceHostname" is the wildcard character "*", then it
identifies all the Ethernet devices of the type specified by "deviceModel".
l
For any combination of "deviceModel" and "deviceId", it needs to be established
whether the device to be updated is on the controller or on a peripheral connected to the
controller:
o
If the "deviceHostname" is defined, then the device to be updated is connected to
an Ethernet-connected parent device.
o
If the "deviceHostname" is not defined, then the device to be updated is connected
to the controller (Cresnet device/internal gateway).
o
If the "deviceHostname" is "*", then all devices will be updated as defined by the
"deviceModel" parameter in one of the following three ways:
n
All gateways will be updated
n
All specific devices connected to internal/external gateways will be updated
n
All Cresnet devices of a specified type connected to a CEN-CN or all EX
devices connected to an external Ethernet gateway will be updated.
IndirectCresnetId
This parameter is only valid when the "deviceModel" specifies an EX device:
l
If the "deviceModel" specifies an EX device, then it indicates the Cresnet ID of the
gateway.
l
If "indirectCresnetId" is "*", then it indicates the specific device connected to any
Cresnet gateway.
l
If the value of this parameter is not defined, then the device to be updated is connected to
the controller (Ethernet device/internal gateway).
