Chapter 2 Basic Concepts
Containment Views
Containment Views
The Cisco EMF Map Viewer application uses a concept called containment views to allow logical
grouping of monitored objects. Objects being managed by Cisco EMF must be added to one or more
containment views. Objects are organized into different views and can exist in multiple views
simultaneously by reference. Objects can be in one or more containment views.
When installed, the Cisco Catalyst Switch Manager does not modify the visible containment views and
all managed objects will appear in the Physical tree. Note that previous versions of the EMS added three
other containment views (Catalyst6000Manager, Catalyst6500Manager and Cisco7600Manager). If
these views are present, the version 2.0 or earlier release of the Manager application is still installed. See
the Cisco 6500/7600 Manager Installation Guide for instruction on removing the previous version of the
Manager.
Views are accessible by clicking the Viewer icon on the Cisco EMF launchpad. These views appear in
the frame at the left of the window when you open the Map Viewer window (see the following figure for
an example).
Views model hierarchical relationships between objects, both physical and logical. Objects are organized
into different views and can exist in multiple views simultaneously by reference. Each object can have
a number of parent and child objects. You can access EM objects by navigating through one of the views
to find specific objects by expanding the text. Click on the plus sign (+) next to any object to expand the
view. A minus sign (–) next to an object indicates there are no more levels to expand; you may, however,
click on a minus sign (–) to collapse the view to the level of the specific object as necessary. Each view
represents a different way of containing and grouping objects.
The EM adds specific views to the standard views supplied by Cisco EMF. The standard Cisco EMF
views are the Physical and Network views.
Note
For further information on views, see the Cisco Element Management Framework User Guide Release
3.2.

EM Views
The number in parenthesis next to a view indicates how many top–level objects are contained within the
view. Notice that the RME and VLAN–QinQ views do not display a number beside the view name. In
addition to the minus sign beside the view name, the absence of a number is a indicator that there are no
objects beneath it.
