The following sections describe how to interpret the status colors related to the COMSPHERE 6700 Series NMS and its proxied devices, and how to access and interpret the dialogs that describe their health and status.
Evaluating Status Colors
You can quickly evaluate the status of a 6700 Series NMS or proxied device by noting its symbol color. Table 3-7 describes the colors and their meaning.

NOTE
For a NetManage, proxy agent, or control channel symbol to reflect the status color of its subobjects, set the Propagate Most Critical parameter using the HP OpenView menu selection File–>Describe/
Modify Map.
Health and Status Display
The read-only Proxied Device Health and Status Display provides status information about a proxied device, as described in Table 3-8. (Appendix A identifies the MIB objects used to generate the display.)
Note that if N/A is displayed in a field, the information is unavailable.
After the status has been displayed, update the information by clicking the Refresh button. To exit the display, click the Cancel button.
Any errors that prevent a task (such as communicating to the COMSPHERE 6700 Series NMS SNMP Proxy Agent) from completing are logged in the HP OpenView Log database (nettl). Any errors returned by the proxy agent are displayed in the status region of the display.
Accessing the Display from the Menu
To access the display from the menu:
1. Select a device by clicking on a proxied device symbol as it appears on an HP OpenView Windows submap.
2. Use the menu selection Monitor–>OneVision Device Mgmt: DCE Manager–>Health and Status to access the display. The selection name of the device is displayed in the title bar.
Accessing the Display from the Command Line
To access the display from the UNIX command line:
TYPE: /usr/OV/bin/att6700Status –target <selection name>
Where: selection name is the selection name of the device

Circuit Quality Table
The read-only Circuit Quality Table is a Network Node Manager Application Builder application that provides the operating characteristics of the data circuit being used by the device, as described later in Table 3-10. (Appendix A identifies the MIB objects used to generate the display.)
NOTE
Circuit quality information is not available for 3550 or 3600 Series devices without the dBM option.
Note that if no value is displayed in a field, the information has not been configured in the device.
After the status has been displayed, update the information by clicking the Restart button. To exit the display, click the Close button.
Any errors that prevent a task (such as communicating to the COMSPHERE 6700 Series NMS SNMP Proxy Agent) from completing are logged in the HP OpenView Log database (nettl). Any errors returned by the proxy agent are displayed in the status region of the display.
1. Select a device by clicking on a proxied device symbol as it appears on an HP OpenView Windows submap.
2. Use the menu selection Monitor–>OneVision Device Mgmt: DCE Manager–>Circuit Quality Table to display the table. The selection name of the device is displayed in the title bar.
Because certain devices may not return certain circuit quality values, it is important to check the Validity of the values returned as described in Table 3-9.

Overview
The DCE Manager enables you to display and set selected configuration parameters (MIB variables) of 3100 Series devices and proxied devices. You can also display configuration information about the COMSPHERE 6700 Series NMS. Additionally, you can use a front panel emulator to configure a proxy device as if you were using the device’s front panel. The first part of the chapter discusses the configuration of 3100 Series devices; the second part discusses the configuration of the 6700 Series proxy agent and proxied devices.
Be aware that although you can only set selected MIB variables via the DCE Manager, you can set any read-write MIB variable using the HP OpenView MIB Browser utility (Monitor–> MIB Values:Browse MIB: SNMP). All the MIBs necessary to manage the 3100 Series devices, proxy agent, and proxied devices are loaded automatically as part of the installation of the DCE Manager.
See Figure 1-2 in Chapter 1 for a illustration of the MIB tree.
