Use this procedure to compare and view the differences
between modeled configurations on a device. The modeled configurations
being compared can be any that exist in the Netcool Configuration
Manager database,
regardless of whether these configurations have been obtained from
an actual network resource or simply entered by a user as a “draft”
configuration.
Before you begin
- Access rights
- Your access rights are determined by group membership, and they
dictate the commands for which you can view any differences.
- For example, if you do not have view rights for 'ntp server',
you would not see any differences for the ntp server command.
- Juniper devices
- The 'show diff' functionality is only available for Juniper devices
that are using SmartModel drivers.
About this task
Generating a list of configuration differences allows
you to quickly view any differences in command values between one
modeled configuration (or a part of that modeled configuration) and
another.
To compare and view the differences between modeled
configurations, follow these steps.
Procedure
- Select the Resource
Browser in
the navigation tree.
The Resource
Browser displays.
- Search for the resources or configurations that you want
to compare.
- Click to highlight the selected devices.
Note: The
Ctrl key may be used to select more than one device. Selected devices
must have the same device model in order to compare.
- Right click and select Show Differences.
Remember: The 'show diff' functionality is only
available for Juniper devices that are using SmartModel drivers.
- If you chose one device, the Show Differences wizard
displays the Select Master and Compared dialog.
Select which device you want to consider the master and click Next.
You can change your selections, and even choose different devices
at this point. In addition, you must choose the same model devices
for comparison. Deciding which device to use as the master is important
if you decide to leave the Show All Differences check
box unchecked. You can click the Switch icon to change your master
and compared selections. Click Next to continue.
- If you chose multiple devices, the Show Differences wizard
displays the Select View of Report dialog.
If the support level of the device/configuration is SmartModel, there
are options for a Modeled view and a Native View.
To
compare and view modeled device configurations:
- Select the Modeled View radio
button. If you want to view all differences, check the Show
All Differences check box.
