Utilizing DNS

A DNS policy will be required to connect to external servers by their name, rather than their IP address. Such services could be AAA, RADIUS, or vCenter.

The DNS service policy is a shared policy, in that any tenant and VRF that uses this service must be configured with the particular DNS profile label.

How to do it...

1. From Fabric, select Fabric Policies | Global Policies | DNS profiles. Right-click on DNS Profiles and select Create DNS Profile.

 

 

2. Name the profile and select the default (Out-of-Band) option next to Management EPG.

3. Click on the plus sign next to DNS Providers and add the IP addresses of the DNS servers. Select the Preferred tick box if you want to.

4. Set the DNS domains in the same manner.
5. Click on SUBMIT. We need to set the labels, again.
6. From Tenants, select the mgmt. tenant.
7. Go to Networking, then to VRFs, and select oob.
8. Scroll down the page in the working pane until you see the DNS labels box.

 

9. Enter the DNS label (Global-DNS-Policy).

10. Click on SUBMIT.
