Known Affected Releases

DNAC-Magneto DNAC1.3.3.7

Description (partial)

Symptom:
Cisco DNA Center's LAN Automation app may fail to start with the message, "Error while reserving the SVI space" error.  The network-orchestration service may return similar errors:

2020-08-31 11:27:17,170 |  ERROR | SimpleAsyncTaskExecutor-1 |  | c.cisco.dnac.error.log.ErrorLogger | NCSU10151: "IPAM Error: Error in assignIpSubnetFromIpPool: "
java.lang.Exception: IPAM return null value.

And the ipam-service may return similar errors:
| 1284 | 2020-08-31 11:27:16,899 |  ERROR | SimpleAsyncTaskExecutor-1 |  | c.c.a.i.e.e.IpamInfobloxException | Connection time out:I/O error on POST request for "https://<IPAM IP>/wapi/v2.9.5/fixedaddress": Read timed out; nested exception is java.net.SocketTimeoutException: Read timed out |
| 1285 | 2020-08-31 11:27:16,968 |  ERROR | SimpleAsyncTaskExecutor-1 |  | c.c.a.i.r.AutoAssignIpsMessageHandler | Error during auto assign ip addresses <LAN Autosubpool>/23 in external ipam: NCIP10119: Connection timeout |

Conditions:
This was observed in Cisco DNA Center 1.3.3.7 when the integrated IPAM takes longer time (more than 10 seconds) to process the data from Cisco DNA Center.
