Just as if you were on the command line, NDFC can create and modify configuration intent for interfaces. In this section, you will learn how to edit or modify an interface using NDFC. Subsequent sections in the lab will introduce you to creating other types of interfaces such vPCs and Loopbacks. Different template policies exist for interfaces that can be assoicated depending on the type of interface. For example, an access interface, which is what you'll be working with in this section, has a template policy for the command line required to make an interface an access port, i.e. switchport mode access.

This section also introduces you to filtering capabilities of NDFC. This capability streamlines the tabular display which allows you to quickly and easily locate the desired item you're working with. The filter option works automatically when you start to type in the filter field. You will be prompted with word completion options to help you select the appropriate filter. Since you're working with interfaces, Interface will be the word you type in this section to begin your filter. Next, the filter needs to know if it's looking to filter on something it's equal to or not. Thus, == ("equals equals") will be used to match the string name of a particular interface. The last option for the filter requires the string name you want to match (or not match). You will want to match the string Ethernet1/5.

Step 1 - Launch Edit Interface Wizard

From the Overview dashboard, you need to navigate to Interfaces to view all the interfaces NDFC is aware of from your switches and begin your next task.

1. Click Interfaces in the top navigation bar
2. There are a lot of interfaces present from all of your switches. The easiest method of locating what you are looking for is through the filter option described above. In the filter option box, type Interface == Ethernet1/5
3. Locate Site1-L1 and Site1-L2, then check both switch's checkbox to select them
4. On the right, click Actions
5. Then click Edit

Step 2 - Launch Policy Template Selection

In the Edit interface wizard, notice Site1-L1 : Ethernet1/5 has no Policy selected. Launch the template policy selection pop up:

1. Click on int_trunk_host link

Step 3 - Select Access Host Policy Template

In the Select Attached Policy Template pop up you will select the policy template that will make your Ethernet1/5 interfaces on your Site1-L1 switch access interface.

1. Click the policy template called int_access_host
2. Click Select

3. Click Save & Next at the bottom
4. Click on int_trunk_host link

5. Click the policy template called int_access_host
6. Click Select
7. Click Save
8. Then click Deploy

Step 4 - Deploy Interface Configuration

After clicking Deploy, NDFC launches the Deploy interfaces configuration wizard. This view should look very similar to what you saw when performing the initial fabric deployment with the two stages and the option to review the pending configuration. Feel free to do so if you desire. Once done:

1. Click Deploy Config in the bottom right


You will see the intended interface configuration starting being deployed for the Ethernet1/5 interface on Site1-L1 and Site2-L1.

Step 5 - Exit Edit Interface

Upon the interface configuration being successfully deployed, NDFC will redirect you back to the Edit interface wizard.

1. Click the at the top right to close the Edit interface wizard

Step 6 - Review Site1-L1 and Site1-L2 Ethernet1/5 Policy

Back at the main Interfaces overview, the filter for Ethernet1/5 should still be active. Locate the Ethernet1/5 interfaces for Site1-L1 and Site1-L2 and ensure the Policies column shows int_access_host

Continue to the next section to create a vPC interface between your Site1-L1 and Site1-L2.
