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 Network Controller can be used to solve these problems by extending a Cisco Multi-Site fabric to Amazon Web Services (AWS), Microsoft Azure, or Google public clouds. You can also mix AWS, Azure, and Google Cloud in your deployment.

This document describes the features, issues, and limitations for the Cisco Cloud Network Controller software. For the features, issues, and limitations for the Cisco APIC, see the appropriate Cisco Application Policy Infrastructure Controller Release Notes. For the features, issues, and limitations for the Cisco Multi-Site Orchestrator/Nexus Dashboard Orchestrator, see the appropriate Cisco Nexus Dashboard Orchestrator Release Notes.

Bug ID                    

Description

Exists in          

CSCwh07187

In GCP Cisco Cloud Network Controller, for the non-default Cloud Account in a Tenant, inventory task is not started until the first CloudCtxProfile / GCP VPC Network is configured in that Account.

Because of this behavior, we cannot do a brownfield import in that Cloud Account until the first CloudCtxProfile is created.

26.0(2h) and later

CSCwh92988

Static Route config is missing in Cisco Catalyst 8000V which is leading to traffic failure.

26.0(2h) and later

CSCwh98098

In Azure Cisco Cloud Network Controller, if a subnet is pointing to the CloudCtxProfile VRF (no RsSubnetToCtx), and if the VRF association of the subnet is changed by addition of RsSubnetToCtx to a different VRF while there is a running instance/VM in the subnet, there will be two instances/VM seen in the Cisco Cloud Network Controller UI.

In the above condition, when the subnet is moved from CloudCtxProfile VRF to another VRF while there is a running instance in the subnet, there will be two HcloudInstance MOs for this VM, one in each of the VRFs.

There is no functional impact because of this issue.

26.0(2h) and later

CSCwe26882

After a Cisco Cloud Network Controller upgrade, there is a banner on Cisco Cloud Network Controller Dashboard which says that the system is still in progress. The banner usually disappears when the Cisco Cloud Network Controller shows that all the Vnet peering is OK. However, the banner could disappear before the Cisco Cloud Network Controller shows all the VNet Peering are OK. There is no functional impact but can cause confusion to the users.

26.0(1c) and later

CSCwe68147

After the L4-L7 configuration is posted, the connector crashes on adding more than 25 firewall VMs on Azure in one request.

26.0(1c) and later

The "Cloud Access Privilege" for certain brownfield Cloud Context Profiles in the tabular view under "Application Management" may sometime show as "Not Applicable"

25.1(1e) and later

CSCwd10789

When we scale up CCRs or manage the CCRs in a region within 1 min after CCR scale down or unmanaging CCRs in a region, the new CCRs will not be programmed with licenses.

A fault on the UI will indicate that the CCR is not programmed with licenses and the hcplatformlicense operational state is down.

25.1(1e) and later

CSCwd10816

Flow filter options may still be available in the statistics chart dropdown after the filter is deleted.

25.1(1e) and later

CSCwc71587

In some cases, the BGP session between the on-premises router and the Cisco Catalyst 8000V router in the cloud is down. Although the crypto sessions and tunnels are up, there could be some traffic loss when this happens.

25.0(5k) and later

CSCwc83944

You might not be able to SSH to the Cisco Cloud Network Controller on Azure after launching it for the first time during first 5-10 minutes of system bringup.

25.0(5k) and later

CSCwa97199

No functional issue, stale licenses are configured on the Cisco Catalyst 8000V. On programming a T2 license on the Cisco Catalyst 8000V, a stale license entry is seen on both the Cisco Catalyst 8000V and the Cisco Smart account.

 

25.0(4k) and later

CSCwb01378

The following fault appears on the Cisco Cloud APIC indicating that the license is not configured on the CCR:

Oper State of HcplatformLicense is down with administrative-down.

25.0(4k) and later

When BFD is enabled between sites, the BFD sessions go down and come back up quickly with no user intervention/trigger.

25.0(4k) and later

CSCwc39392

In a few specific cases, on importing a brownfield VNet with a Routing & Security access policy, an NSG might not get created and/or VNets might not peer.

25.0(4k) and later

CSCvx16601

When the "AllowAll" flag is enabled on a service device such as a native load balancer or on the logical interface of a third party device, it is possible that to see some specific rules apart form a rule that allows all traffic from any source to any destination.

25.0(1c) and later

CSCvy89617

Cloud routers may not get created if external network objects are not configured. External network configuration is required for configuring cloud routers.

25.0(1c) and later

CSCvy97972

Cisco Cloud APIC in this release limits the number of regions where we can deploy the hubnetwork in order to establish external connectivity. When you attempt to deploy/configure hubnetwork in more than four regions, the configuration will be rejected with the following error:

Invalid Configuration CT_INTNETWORK_REGION_MAXIMUM: At present, there can be at most 4 cloudRegionName in cloudtemplateIntNetwork uni/tn-infra/infranetwork-default/intnetwork-default; current count = <total-hubnetwork-regions-attempted>

Bug ID                    

Description

Exists in          

CSCvo06626

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.

25.0(1c) and later

CSCvo30542

TACACS monitoring of the destination group is not supported through the GUI.

25.0(1c) and later

CSCvo55112

Logs are lost upon stopping the Cloud APIC instance.

25.0(1c) and later

CSCvo95998

There is traffic loss after a Cloud APIC upgrade. Traffic will eventually converge, but this could take a few minutes.

25.0(1c) and later

CSCvq11780

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.

25.0(1c) and later

CSCvq76039

When a fault is raised in the Cloud APIC, the fault message will be truncated and will not include the entire cloud message description.

25.0(1c) and later

CSCvr01341

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.

25.0(1c) and later

CSCvu05329

The Ctx Oper managed object is not deleted after the attachment is deleted.

25.0(1c) and later

CSCvu64277

Stats seen on Cisco Cloud APIC are sometimes not in sync with Azure stats.

25.0(1c) and later

CSCvu72354

Adding an EPG endpoint selector fails with an error message saying the selector is already attached.

25.0(1c) and later

CSCvu78074

Route nextHop is not set to the redirect service node specified in the service graph.

25.0(1c) and later

CSCvu81355

Traffic gets dropped after downgrading to the 5.0(1) release. Cloud Services Router has incompatible configurations due to an issue with reading configurations using SSH.

25.0(1c) and later

CSCvu88006

On the Dashboard, fewer VNet peerings are shown than expected.

25.0(1c) and later

CSCvv32664

When the CSR bandwidth needs to be increased, the user needs to undeploy all the CSRs in all the regions and redeploy with the desired bandwidth, which can cause traffic loss.

25.0(1c) and later

CSCvv81647

When an invalid Cloud Services Router license token is configured after initially configuring a valid token, the Cloud Services Router fails the license registration and keeps using the old valid token. This failure can only be found from the CSR event log.

25.0(1c) and later

CSCvw05821

Redirection and UDR does not take effect when traffic coming through an express route and destined to a service end point is redirected to a native load balancer or firewall.

25.0(1c) and later

CSCvw07392

Inter-site VxLAN traffic drops for a given VRF table when it is deleted and re-added. Packet capture on the CSR shows "Incomplete Adjacency" as follows:

Punt     1    Count       Code  Cause    1           10    Incomplete adjacency  <<<<<<<

Drop     1    Count       Code  Cause    1           94    Ipv4NoAdj

25.0(1c) and later

CSCvw07781

There is complete traffic loss for 180 seconds.

25.0(1c) and later

CSCvw24376

Inter region traffic is black-holed after the delete trigger for contracts/filter. It was observed that the TGW entry pointing to the remote region TGW is missing for the destination routes. On further debugging it was found that post delete trigger as part of re-add flow, when a describe call is sent to AWS got a reply with the state of this entry as "active" because of which a new create request is not being sent.

25.0(1c) and later

CSCvw39814

Infra VPC subnet route table entry for 0.0.0.0/0 route with TGW attachment as nh, is left as a stale entry upon being undeployed. There is no functional impact. Upon being redeployed, this entry is updated with the correct TGW attachment ID as nh.

25.0(1c) and later

CSCvw40737

SSH to a virtual machine's public IP address fails, despite the NSG allowing the traffic inbound. SSH to the private IP address of the virtual machine from within the VNet works.

25.0(1c) and later

CSCvw40818

After upgrading Cloud APIC, the Cloud Services Routers will be upgraded in two batches. The even set of CSRs are triggered for upgrade first. After their upgrade is complete and all of the even CSRs are datapathReady, only then the odd set of CSRs will be triggered for upgrade. When even one of the upgrade of the even CSRs fail and they don't become datapathReady, the odd set of CSRs will not be triggered for upgrade. This is the behavior followed to avoid any traffic loss.

25.0(1c) and later

CSCvw48190

When Cloud APIC is restart, the VPN connection from a tenant's VNets will get deleted and re-created, one by one. This can be seen in the Azure activity logs. It should not impact traffic, as all connections are not deleted at the same time.

25.0(1c) and later

CSCvw49898

When the downgrading from the 5.2(1) release to the 5.0(2) release, traffic loss is expected until all of the CSRs are downgraded back to the 17.1 release. The traffic loss occurs because when the CSRs are getting downgraded to the 17.1 release, the CSR NIC1s will be in the backendPools and traffic from the spokes will still be forwarded to the native load balancer. The traffic gets blackholed until the CSRs get fully programmed with all the configurations in the 17.1 release.

25.0(1c) and later

CSCvw50918

Upon downgrading Cloud APIC, VPN connections between Cloud APIC and the cloud (AWS/Azure VPN gateway) will be deleted and re-created, causing traffic loss. Traffic loss is based on how quickly the VPN connections are deleted and re-created in AWS due to AWS throttling.

25.0(1c) and later

CSCvw51544

A user who is assigned a large number of security domains may not be able to create other Cisco ACI policies.

25.0(1c) and later

CSCvw55088

A user who is assigned a large number of security domains may not be able to create other Cisco ACI policies.

25.0(1c) and later

CSCvx91010

When TGW Connect is disabled, traffic loss is observed for about 8 minutes.

25.0(1c) and later

CSCvx98260

When delete followed by add operations of tenant or other resources (such as VPCs and contracts) are done within a short span of time, it is possible that the resource deployment in Google Cloud may get out of sync with the configuration on Cisco Cloud APIC. The likelihood of this happening is directly proportionate to the scale of configuration and how quickly the operations are done.

We may see resources either not created or not deleted on Google Cloud to match the user configuration on Cisco Cloud APIC.

25.0(1c) and later

CSCvy06610

The eventmgr crashes when handling a fault triggered by a new cloud account.

25.0(1c) and later

CSCvy10936

Downgrading Cisco Cloud APIC from release 5.2(1) to 5.1(2) may cause CSRs to not be downgraded. The CSR release for 5.2(1) is 17.3.2, and the CSR version for release 5.1(2) is 17.3.1. After the Cisco Cloud APIC downgrade, the CSR version should be downgraded to 17.3.1,  but it will not happen due to this bug.

25.0(1c) and later

CSCvy12722

Loss of traffic between a cloud and Cisco ACI On-Premises deployment.

25.0(1c) and later

CSCvy13369

After upgrading AWS, infra vPC peering does not get deleted.

25.0(1c) and later

CSCvy19286

There is traffic loss after downgrading from 5.2(1) to 5.1(2).

25.0(1c) and later

CSCvy28890

There is a loss in SSH connectivity to the Cisco Cloud APIC across reboots. But, after a few minutes, the connection should come back and users will be able to SSH in to the Cisco Cloud APIC again.

25.0(1c) and later

CSCvy28896

There is an increase in the connector's memory utilization. All of the CSR workflows rerunning might happen even after the setup is in the steady state.

25.0(1c) and later

CSCvy30314

After upgrading the Cisco Cloud APIC, on the TGW route tables, the default route (0.0.0.0/0) does not point to infra VPC attachment or is missing. In this case, traffic intended to get forwarded to the CSR will be dropped or forwarded to an invalid next-hop.

25.0(1c) and later

CSCvy33435

There is intersite traffic loss when TGW Connect is enabled.

25.0(1c) and later

CSCvy34180

Cloud Intersite traffic is dropped due to the CSR in the cloud site not advertising the EVPN routes.

25.0(1c) and later

CSCvy45517

The Cisco Cloud APIC GUI shows the total allowed count for CtxProfile, VRF (fvCtx), EPGs, and contracts. These numbers have been validated only for Azure-based deployments. For AWS deployments, the numbers supported are much lower.

25.0(1c) and later

CSCvy77233

Routes for subnets that are not yet configured in Google Cloud may become visible on an external device. When you configure routes to be advertised to an external device, but don't actually configure subnets in the cloud that you intend to advertise the routes for, those routes are still advertised.

Remote router may see routes that are advertised even when the subnets are not yet configured.

The traffic will get dropped because the subnets are not actually configured.

25.0(1c) and later

CSCvz11574

The cloud VRF egress route table is missing the route for 0.0.0.0/0 via the Internet Gateway (IGW), which leads to issues with ssh for VMs in the cloud VRF.

25.0(1c) and later

CSCvz20282

An upgrade to or downgrade from the Cloud APIC 5.2(1g) release to any release while using "Ignore Compatibility Check: no" will fail. The following fault is raised: "The upgrade has an upgrade status of Failed Due to Incompatible Desired Version."

25.0(1c) and later

CSCvz49747

When delete followed by add operations of tenant or other resources (such as VPCs and contracts) are done within a short span of time, it is possible that the resource deployment in Google Cloud may get out of sync with the configuration on Cisco Cloud APIC. The likelihood of this happening is directly proportionate to the scale of configuration and how quickly the operations are done.

We may see resources either not created or not deleted on Google Cloud to match the user configuration on Cisco Cloud APIC.

25.0(1c) and later

CSCwa08564

UI dashboard shows the wrong status for inter-region connectivity.

25.0(2e) and later

CSCwa28888

This issue is hit in some cases where Cloud APIC is unable to deploy infra configuration, such as creating cloud routers in overlay-1 VPC. This is sometimes seen in new deployments, but not in the case of upgrade scenario. Cloud routers and other configurations do not get deployed in Google Cloud.

25.0(2e) and later

CSCwa36940

Transit gateway external connectivity is not getting deployed in regions where cloud context profiles are deployed.

25.0(2e) and later

CSCwa40705

When an IKEv1 tunnel is configured to a destination while another tunnel already exists to the same destination but with a different source interface, this tunnel will remain with the protocol shown as down.

25.0(2e) and later

CSCwa45047

This is not a functional issue. There will be no fault shown in the Cloud APIC UI if the border gateway protocol sessions of the transit gateway external connectivity are down.

25.0(2e) and later

CSCwa49263

In VPC route table, the route table entry for a destination CIDR pointing to transit gateway is sometimes missing when a quick delete and add of tenant or contract is done or when we move from transit gateway connect to legacy transit gateway solution. This happens only with legacy transit gateway solution in either of the cases.

This is a timing issue with the legacy transit gateway solution, where we create two transit gateways per hub network in a region. This can happen either if we move to legacy transit gateway solution or if legacy transit gateways are coming up for the first time.

These conditions result in deleting the route table entry for a given destination CIDR and adding back the same entry at the same time. Due to an issue with the AWS API which returns a deleted route table entry as a non deleted entry, Cloud APIC deletes the wrong entry.

25.0(2e) and later

CSCwa92698

If the Cloud APIC infra CIDR has a collision with the reserved CIDR 172.17.0.0/16, connectivity to the Cat8kv VMs from Cloud APIC VM might fail. If the connectivity fails, the configuration push to Cat8kv will fail and Cat8kv will remain unreachable from Cloud APIC. A fault will be raised in the Cloud APIC.

Currently 172.17.0.0/16 is reserved by Cloud APIC and it cannot be used as Infra CIDR. 172.17.0.0/16 is used by the docker network running on Cloud APIC.

25.0(3k) and later

CSCwc11244

In this case the HcloudCtxOper of infra VNet, which is used to deploy NLB/ALB, is down. Since one of the network interface associated with the Vnet is in a failed state, Cisco Cloud APIC is unable to add a new Cidr to the VNet.

25.0(4k) and later

CSCwd20102

Statistics page for Azure stats might contain missing data in the GUI when Azure cloud reports data incorrectly.

25.1(1e) and later
