Detecting and Managing Manual CLI Configuration Changes
Contrail Networking Release 2003 supports the detection of manual CLI configuration changes. You can either accept these manual changes as part of the configuration, or you can reject the CLI changes and remove the manual change from the configuration. Starting in Contrail Networking Release 2008, you can also ignore manual CLI configuration changes.
For example, consider a scenario where a user logs in to the command line interface of a fabric device, makes changes to the existing configuration, and commits the configuration. Contrail Command detects such manual CLI configuration changes. You can then choose to accept, ignore, or reject the change.
When you make configuration changes by using the command
line interface, ensure that you do not use – ;
{ } [ ] , in the description field. Using these characters
would cause the CLI detection workflow to fail.
You can view the following information before you accept, ignore, or reject the new CLI configuration change.
The user who made the change.
The time the change was made.
The actual change in configuration.
These topics provide instructions to detect, accept, ignore, and reject manual CLI configuration changes.
Detecting a CLI Change
Contrail Command can detect a manual CLI change when
You run the View Configuration job.
For steps to view device configuration, see Viewing Configuration of Devices Deployed in Contrail Fabric.
You upgrade a device image.
For more information on upgrading a device image, see Image Management.
You run a fabric job such as Reconfigure Roles.
For more information on reconfiguring device roles, see Reconfigure Roles.
As an example, consider that you have made a CLI configuration change on a fabric device. Follow these steps to detect the manual CLI configuration change when you run the View Configuration job.
- To view configuration of a device, select the check box
next to the device name and click the View Configuration icon. See Figure 1.Figure 1: View Configuration Icon
The Device Configuration tab is displayed.
The device that you have selected to view configuration for is listed in the Operation is being run on the following devices table. The status of the view configuration job for the device is displayed in the Status column next to the device name.
If there is a manual change in configuration, the job status is Review Changes. If there is no change, the status is a green tick mark. See Figure 2.
Figure 2: View Configuration Job Status
After the view device configuration job is completed, navigate to the Fabric devices page to view the status of all devices. A device is in the Changed status when there are new manual CLI changes made. Devices with no manual CLI changes are in the Active status. See Figure 3.
Figure 3: Status of a Fabric Device
For more information on reviewing changes, see Accept, Ignore, or Reject a CLI Change.
After you upgrade a device image or after you run the reconfigure roles fabric job, navigate to the Fabric Devices page to determine if the device is in the Changed status. If the device is in the Changed status, Contrail Command has detected that the device has a new CLI configuration change.
Accept, Ignore, or Reject a CLI Change
After Contrail Command has detected a CLI configuration change, you can accept, ignore, or reject CLI changes.
Follow these steps to accept, ignore, or reject a CLI change by using the Contrail Command UI.
- Select the check box next to the device name to view details
of the user who made the change and the time the change was made.
This information is displayed in the Configuration Changes for device table as show in Figure 4.
