Change [Device] Poll List (chpl)
(Disruptive for DATAPHONE II APL Modems and DSUs, and
3600 Series DSUs When Adding Tributaries)
Use the chpl command to add or delete devices in the poll list of a COMSPHERE
3400/4400 Series modem, a COMSPHERE 3900 Series modem, a COMSPHERE 3600 Series
DSU, a DATAPHONE II APL modem, DSU, or Shared Diagnostic Unit (SDU).
Polling is the process by which alarms from devices in the network are automatically reported to
the NMS. Once a poll list is established for a device, the device monitors everything on its poll list
for health and status.
The NMS polls devices on the control channel. Those devices then poll devices downstream, and
so on through the extended diagnostic network. A device always reports the health and status of all
devices on its poll list to the device that polls it. NMS is, therefore, able to obtain health and status
for all diagnostic devices in the network by polling only devices on the control channel.
For most commands, NMS enables you to specify the destination for the command’s results and
schedule its execution. If the last page of the input form cannot accommodate the Destination for
results and Schedule execution fields, an additional page is provided. For a complete description
of these fields, refer to Chapter 1, Introduction.
