Limitations and Restrictions
Cisco DNA Center VA on AWS has the following limitations and restrictions:
-
Support for only one on-premises IPsec tunnel is available in this release.
-
Support for multiple IPsec tunnels is not available, so you cannot have pre-existing IPsec tunnels.
-
Configuration for the Existing Transit Gateway (TGW) and Existing Customer Gateway (CGW) scenario is not available in the automated deployment method. You must manually configure this routing as discussed in the Cisco DNA Center Virtual Appliance on AWS Deployment Guide.
-
Any manual alterations made to the automated configuration workflow of Cisco DNA Center VA on AWS can cause conflict with the automated deployment. We recommend against making manual changes with Cisco DNA Center VA Launchpad through the AWS console, because it can lead to issues that Cisco DNA Center VA Launchpad cannot resolve.
-
You can only create one Cisco DNA Center per VA pod.
-
Reusing a CGW to create a new VA pod in the same region is not supported.
-
Multiple users should not update their email IDs concurrently. If this occurs, the latest updated email ID is used for email notification.
-
The Amazon CloudWatch alarms for lambda functions remain in the insufficient data state unless a failure occurs in the corresponding lambda function execution. When a lambda function fails, Amazon CloudWatch gathers the metrics and triggers the alarm. The threshold for all lambda alarms is one, so Amazon CloudWatch can capture alerts if there are any failures.
-
For some alarms, like S3, the metrics are only reported once per day at midnight in Greenwich Mean Time (GMT) or 00:00 UTC. So, it can take 24 to 48 hours for the dashboard metrics to be updated, which is an expected behavior.
-
Deleting a VA pod on Cisco DNA Center VA Launchpad can take approximately 20 to 40 minutes.
-
Cisco DNA Center VA Launchpad does not support local zones and wavelength zones. Only AWS availability zones are provided for regions.
The r5a.8xlarge instance size is not supported for the us-east-1e availability zone in the us-east-1 region and the sa-east-1b availability zone in the sa-east-1 region.
