When working with the BlueCat Cisco DNA Generic IPAM Driver, the following known issues exist:
- If you modify any settings within a Global Pool, such as the servers or gateway address, the changes are not reflected in Address Manager unless you also update the name of the Global Pool. Once the Global Pool name is updated, the additional changes are reflected in Address Manager.
- When releasing the Global Pool using the Cisco DNA Generic IPAM Driver API, you can incorrectly release the Global Pool even if there is an IP address assigned within the Global Pool. You cannot delete a Global Pool unless the pool is empty and there are no IP addresses assigned within the pool. The Cisco DNA Center UI catches this issue; however, the Cisco DNA Generic IPAM Driver API does not.
- When integrating the Cisco DNA Generic IPAM Driver workflow with Cisco DNA Center, if an assigned Global IP Pool exists, this is not imported into Address Manager automatically. The network will be created upon assigning IP addresses using the API.
- When adding a Sub-Pool that has the same CIDR as the parent IP Address Pool, the Sub-Pool can be added to Cisco DNA Center UI; however, no Cisco DNA Generic IPAM Driver API will be triggered, resulting in the Sub-Pool not being added to Address Manager. The network will be created upon assigning IP addresses using the API.
- You cannot retrieve the network IPv6 gateway property.
- When deleting DNS/DHCP Servers in the Cisco DNA Center UI, messages are not sent to the Cisco DNA Generic IPAM Driver to delete the servers and the DNS/DHCP Servers are not cleared from the global pool.
- If the BlueCat Cisco DNA Generic IPAM Driver container goes down, you cannot add
new resources within Cisco DNA Center until the plug-in container is restored.
Note: BlueCat recommends configuring two Cisco DNA Generic IPAM Driver instances on the same network: one that acts as a primary instance and one that acts as a standby instance in the event of an outage with the primary instance. If the primary BlueCat Cisco DNA Generic IPAM Driver container goes down, you can switch to the standby Cisco DNA Generic IPAM Driver instance to maintain service while repairing the primary instance.
In the event that you configure only one instance of the Cisco DNA Generic IPAM Driver that goes down, and you cannot restore it and must remove the plug-in to restore Cisco DNA Center service, contact Cisco support for assistance.
