COMSPHERE 6800 Series Network Management System1-6 January 1997 6800-A2-GB20-20PollingAlarms from devices in the network are automatically reported to the 6800 Series NMS via thepolling process. The 6800 Series NMS polling process consists of two steps. First, the NMSestablishes a poll list of the local control modems, DSUs, and Shared Diagnostic Units (SDUs)through entries in the device profiles of these local control devices or via the Acquire ModemControl Channel Poll List (acmccpl) command. Thereafter, the NMS continuously polls each localcontrol device on its poll list. For a discussion of NMS poll lists, refer to COMSPHERE 6800Series Network Management System User’s/System Administrator’s Guide.Each control modem and DSU must then establish a poll list of its tributary devices. Tributarydevices must then establish a poll list of extended control devices. You can cause a device toestablish its poll list by executing the Acquire Poll List (acpl) or Change Poll List (chpl) command.Also, in the case of DATAPHONE II DDD devices, each local SDU must establish a poll list of itsDDD modems. After a poll list is established, the control modem, DSU, and SDU poll each deviceon its poll list. When alerts are detected by the polling of these control devices, they are reportedback to the NMS when the local control devices are polled.To establish a modem, DSU, or SDU poll list, execute the following commands:Acquire Poll List (acpl)This command directs a control modem or DSU to compile a poll list automatically bypolling all allowable addresses one diagnostic level below it. A device is added to the polllist when it responds to the poll. This command is also used to establish an SDU poll listby polling the SDU’s serving dataset slots to determine if a DDD modem is present. If aDDD modem responds, it is added to the SDU poll list.Each device on the poll list has a unique address based upon its location within thenetwork. Refer to Appendix D of the COMSPHERE 6800 Series Network ManagementSystem User’s/System Administrator’s Guide for more detailed information on deviceaddressing.Change Poll List (chpl)This command allows you to add or delete a device manually from a control modem’s orDSU’s poll list, or to change a device’s polling status from active to inactive so that it isskipped during the polling process. This command also allows you to perform the sametask with each local SDU and its DDD modems. You can use this command to add alimited number of devices to a poll list, or to otherwise update an existing poll list.Refer to the COMSPHERE 6800 Series Network Management System Communications ProductsSupport Command Reference Manual for additional information on these commands.
