Introduction
If you have a private cloud, you might run part of your workload on a public cloud. However, migrating workload to the public cloud requires working with a different cloud provider interface and learning different ways to set up connectivity and define security policies. Meeting these challenges can result in increased operational cost and loss of consistency. Cisco Cloud Application Policy Infrastructure Controller (APIC) can be used to solve the these problems by extending Cisco Application Centric Infrastructure (ACI) Multi-Site fabric to Amazon Web Services (AWS) or Microsoft Azure public clouds. You can also mix AWS and Azure in your deployment
This document describes the features, issues, and limitations for the Cisco Cloud APIC software. For the features, issues, and limitations for the Cisco APIC, see the Cisco Application Policy Infrastructure Controller Release Notes, Release 4.2(7). For the features, issues, and limitations for the Cisco ACI Multi-Site Orchestrator, see the Cisco ACI Multi-Site Orchestrator Release Notes, Release 2.2(4).

| TACACS monitoring of the destination group is not supported through the GUI. |
4.2(7f) and later |
|
| Changing an ExtEPG subnet prefix's mark from A to B will end up messing up BGP's prefixes in the CSR and will cause traffic loss. |
4.2(7f) and later |
|
| With a larger number of Cloud APIC tenant EPGs and if the VRF configuration is pushed through the API in a single transaction, sometimes duplicate AWS resources are created. |
4.2(7f) and later |
|
| Cannot access the serial console of the CSR virtual machine in Azure. |

| No NSG is assigned when the cloud endpoint should be classified in the EPG. |
4.2(7f) and later |
|
| A network interface in a Cloud APIC managed region in AWS or Azure matches the EP Selector in a cloud EPG, but the Security Group of that cloud EPG does not get attached to the network interface. Instead, the Security Group of another cloud EPG gets attached to the network interface. |
4.2(7f) and later |
|
| A network interface in a Cloud APIC-managed AWS region matches the endpoint selector in a cloud EPG, but the security group for the cloud EPG does not get attached to the network interface. |
4.2(7f) and later |
|
| If you try to deploy Cloud APIC to an unsupported region, then the Azure portal will allow you to select the region and will fail during deployment. |
4.2(7f) and later |

| Bug ID |
Description |
Exists in |
| When a cloudExtEpg matches on a 0/0 network and has a bi-directional contract with two cloud EPGs, such as cloudEpg1 and CloudEpg2, this can result in inadvertent communication between endpoints in cloudEpg1 and cloudEpg2 without a contract between the two EPGs themselves. |
4.2(7f) and later |
|
| Logs are lost upon stopping the Cloud APIC instance. |
4.2(7f) and later |
|
| There is traffic loss after a Cloud APIC upgrade. Traffic will eventually converge, but this could take a few minutes. |
4.2(7f) and later |
|
| Creating VPN connections fail with the "invalidCidr" error in AWS or the "More than one connection having the same BGP setting is not allowed" error in Azure. |
4.2(7f) and later |
|
| When a fault is raised in the Cloud APIC, the fault message will be truncated and will not include the entire cloud message description. |
4.2(7f) and later |
|
| REST API access to the Cloud APIC becomes delayed after deleting a tenant with scaled EPGs and endpoints. The client needs to retry after receiving the error. |
