Working with topology maps
Modifying a service from the topology view
The topology view for a service provides a graphical representation of the various components and their interconnections. You can also use this view to add, modify, or just navigate to service components. This provides an alternative approach to performing these functions from the navigation tree view in the service configuration forms.
Working from the topology view can expedite the creation of the components, since many of the fields you would ordinarily have to set in the configuration forms will be automatically populated using this approach. The configuration forms can also be accessed directly at any time from this view by right-clicking a component. This allows quick access to conduct more detailed component configuration.
Services that can be modified from their topology views include VPLS, VPRN, VLL, IES, and composite services. See the appropriate service management chapter for procedures that describe how to modify services from the topology view.
Managing OAM diagnostics from the topology view
An NFM-P operator can configure and execute OAM diagnostic tests from the service topology or composite service flat topology view. A right-click contextual menu of test types and test operations allows a GUI user to perform many test-management tasks. The OAM diagnostic functions on the map are enabled and disabled using a selector in the map window.
NFM-P OAM diagnostic test management using the service topology map is supported for the following service types:
The NFM-P OAM diagnostic test management functions are also available for composite services using the composite service flat topology map.
You can use a contextual menu option to open a test-creation form for selected map objects such as NEs, SAPs, SDPs, MEPs, and MIPs. The form is automatically populated with the information for the selected objects. After you apply the test configuration, you can use the map to execute the test and view the results. A test result summary is viewable using statically displayed or mouse-over global info tables that are shown beside the object that initiates the test. By default, the info table for a tested object displays the five most recent test results; you can enable or disable the display of individual or all results.
The general OAM contextual menu options that are available include the following:
-
Create OAM Tests—lists the tests that are appropriate for the service type and selected objects; choosing a test type opens the pre-populated test-creation form
-
Select OAM Tests—opens a filterable list form from which you can choose previously created tests associated with one or two objects
Note: The tests that are listed using the Select OAM Tests option do not include generated tests, or manually added first-run or last-run tests in a test suite.
See To use OAM diagnostic functions on service topology and composite service flat topology maps for information about enabling basic OAM-related map functions.
See To configure and run OAM tests contextually for information about contextually configuring and executing OAM tests for entities and services on topology maps.
Working with Ethernet CFM objects
You can configure and manage Ethernet CFM objects such as MEGs, MEPs, and MIPs using the Ethernet CFM contextual menu option. MEPs and MIPs are represented iconically. For example, a SAP or SDP binding object can have a graphical connector to MEPs and MIPs, and a site object can be connected to a B-VPLS MEP.
Within a MEG, MEPs can be divided into logical groupings called sub-groups. A MEG which contains sub-groups is called a Global MEG. When created, a Global MEG has by default one subgroup.
A service topology map displays only one MEG at a time. The MEG is selectable using a drop-down menu in the map window when the OAM function on the map is enabled. The CFM objects associated with the currently selected MEG are displayed.
For a MEP, the following attributes are displayed:
-
the MEP direction, as the up or down direction in which the icon points
-
the MEG sub-group to which the MEP belongs, as the icon outline color.
Note: For composite services, MEP generation does not occur for for VLAN uplinks and overlapping service sites.
When the Show Test Options check box is enabled, the roles assigned to MEPs for Test Suite Generation are displayed beside the MEP icons. The roles are Target, Source, and Hub or Spoke. See To use OAM diagnostic functions on service topology and composite service flat topology maps .
For a MIP, only the level is displayed.
The displayed Ethernet CFM contextual menu options for MEPs and MIPs depend on the Ethernet CFM configuration, for example, the MD level and whether MEPs and MIPs are already in the MEG.
When an operator right-clicks on the map background, the Ethernet CFM options are:
-
global MEG creation, which opens a configuration form populated with the selected sites or all service sites, if none are selected.
When the selected object is a SAP, you can create, view, change and delete MEPs. See To configure an Ethernet CFM MD policy and subordinate objects for information about configuring MEPs. You can enable, disable, and view MIPs. Enabling a MIP creates a MIP only when the configuration supports this function.
When the selected object is a VLAN uplink, a solid line is displayed between the two SAPs and an OAM icon is displayed above the port icons. Right-click on the OAM icon to display the following Ethernet CFM options:
When the selected object is an SDP binding, you can enable, disable, and view the associated MEPs.
Note: When you enable a MIP on a SAP or SDP binding, the NFM-P creates a MEG site if one does not exist, and uses explicit MHF creation.
