Modeling Gateway Toolkit

casp1032
The 
CA Spectrum
 Modeling Gateway toolkit lets integrators import and export network topology data into and out of 
CA Spectrum
. The toolkit includes a Document Type Definition (DTD) that defines XML elements and attributes. The toolkit also includes a resource file that defines 
CA Spectrum
 syntax and what information to import or export.
For a topology import, using the DTD elements, you can create an XML file that describes devices, ports, and connections on your network. This XML file can create new topology data in 
CA Spectrum
, update existing data, or can destroy data that is no longer correct. Additionally, the elements and attributes that are used in the XML syntax can be expanded and customized to suit the needs of most integrations.
The toolkit also lets you use comma-delimited ASCII text files to import Frame Relay or ATM connections. You can also import this connection information using the XML functionality that was mentioned previously.
Once the network topology data exists in 
CA Spectrum
, you can manage these devices like any other models that are created manually or by Discovery. You can view the results of the import, as well as any diagnostic information about each import.
The Modeling Gateway toolkit also lets you export topology information and configuration settings from 
CA Spectrum
 using an XML file. The information can then be imported into a specified 
SpectroSERVER
 through the Modeling Gateway.
Populating 
CA Spectrum
 with dynamic network topology information on an ongoing basis was previously a difficult task. Discovery and manual modeling are not suited to the constant updates necessary in a changing environment. Modeling connectivity using Discovery can also be a challenge with various physical infrastructures, such as those found in these environments:
  • Cable MSO (Multi-Service Operator)
  • ATM (Asynchronous Transfer Mode)
  • Frame Relay
  • Wireless Devices
When you use the Modeling Gateway with devices located in a Secure Domain, you need to add the attribute details of the secure domain to the import to allow the Modeling Gateway to find models in question and discover the secure domain. Normally, devices can be found with just the device IP.
Example: (Device ip_dnsname="x.x.x.x" secdomain_ipname="y.y.y.y" )"
Modeling Gateway Export and Import Support for World and TopOrg Views
Spectrum 10.3 supports an out of the box approach to export and import xml files via Modeling Gateway for
World
 and
Top_Org 
models. This support is beneficial for customers moving from Spectrum 10.3 to any higher version. 
By default the 'RootContainderToExport' value is '
Universe
'.
To export models under
World
View: 
  1. In the $SPECROOT/SS-Tools\modelinggatewayresource.xml file, change the RootContainerToExport value to '
    World
    '. 
To export models under
TopOrg
View:
  1. In the $SPECROOT/SS-Tools\modelinggatewayresource.xml file, change the RootContainerToExport value to '
    Top_Org
    '.
Modeling Gateway support for Wireless Devices
From Spectrum r10.1, you can import and export topology data and configuration settings for wireless devices from and to Spectrum. However, AccessPoint devices are not supported by the Modeling Gateway Toolkit.
To discover and model AccessPoint devices, follow these steps:
 
  1. Import the relevant comma-delimited ASCII text/ XML file, using the 
    Modeling Gateway Toolkit
    .
  2. Navigate to 
    Explorer View > WLC Manager > Information Tab > Configuration 
    sub-view
     >  Access Point Discovery: 
    and then click 
    Run.

All existing access points 
(APs)
 will be created under their corresponding 
WLC  Device
(s).  
CA Spectrum
 Modeling Gateway is an effective solution for these problems.
