When adding or updating Global IP Address Pools and Sub-Pools in Cisco DNA Center, you can map DNS/DHCP Servers that have been added in Cisco DNA Center to those Global IP Pools and Sub-Pools. Mapping the DNS/DHCP Servers to the pool in Cisco DNA Center adds a deployment role to the DNS/DHCP Server in Address Manager.

The servers in Cisco DNA Center that have the same interface IP address as the DNS/DHCP Server address in Address Manager will receive deployment roles in Address Manager. If the IP addresses do not match, a deployment role is not added in Address Manager and a warning is logged to the log file. The first server address assigned in the pool receives the primary role and the other server addresses receive a secondary role.

Before you begin

Ensure that you have DNS/DHCP Servers managed by Address Manager and that the DNS/DHCP Servers have been imported into Cisco DNA Center. For more information on importing DNS/DHCP Servers into Cisco DNA Center, refer to Importing DNS/DHCP Servers into Cisco DNA Center.



To add servers to IP Pools
  1. Log in to your Cisco DNA Center instance.
  2. In the menu, select Design > Network Settings.
  3. In the Network Settings page, select the IP Address Pools tab.
  4. Within the IP Address Pools table, select the name of an existing IP address pool or add a new IP address pool
  5. Under DHCP Server(s), enter the IP address of the DNS/DHCP Servers that you would like to assign DHCP roles.
  6. Under DNS Server(s), enter the IP address of the DNS/DHCP Servers that you would like to assign DNS roles.
  7. Click Save to update the existing IP address pool or add the new IP address pool.
Verifying that the deployment role has been assigned
  1. Log in to your Address Manager instance.
  2. Select the IP Space tab.
  3. Under IPv4 Blocks, select the name of the IPv4 block that is associated IP address pool that you just added or edited in the Cisco DNA Center instance.
  4. Select the Deployment Roles tab.

If the DNS/DHCP Servers were successfully assigned to the IP address pool, the names of the associated DNS/DHCP Servers appear with the appropriate deployment roles in the Address Manager UI.

If the DNS/DHCP Servers were not successfully assigned to the IP address pool warning messages are logged. The following are example warning messages that appear within the logs:
2021-11-11 09:18:17,291 [WARNING] [CISCO-DNAC-2] Note: DHCP Server '6.6.6.6' doesn't exist under view 'test'
2021-11-11 09:18:17,291 [WARNING] [CISCO-DNAC-2] Note: DNS Server '7.7.7.7' doesn't exist under view 'test'
