Cisco Nexus Dashboard and Services

Cisco Nexus Dashboard is a central management console for multiple data center fabrics and a common platform for hosting Cisco data center operation services. These services are available for all the data center fabrics and provide real-time analytics, visibility, assurance for network policies and operations, as well as policy orchestration for the data center fabrics, such as Cisco Application Centric Infrastructure (ACI) or NX-OS deployments spanning LAN Fabric, SAN, and IP Fabric for Media (IPFM) networks. The services are as follows:

●     Cisco Nexus Dashboard Fabric Controller (NDFC): A comprehensive management solution for all Cisco NX-OS deployments spanning LAN, SAN, and IP Fabric for Media (IPFM) networks in data centers powered by Cisco. Cisco NDFC also supports devices such as IOS XE switches, IOS XR routers, and third-party devices. Being a multi-fabric controller, Cisco NDFC manages multiple deployment models such as VXLAN EVPN, classic 3-tier, FabricPath, and routed fabrics for LAN while providing ready-to-use control, management, monitoring, and automation capabilities. In addition, when enabled as a SAN controller, NDFC automates Cisco Multilayer Director Switches (MDS) and Cisco Nexus-family infrastructure in NX-OS mode with a focus on storage-specific features and analytics.

●     Cisco Nexus Dashboard Insights: Simplifies and automates visibility, troubleshooting, root-cause analysis, and remediation of network issues. By ingesting real-time streamed network telemetries from all devices, Nexus Dashboard Insights provides pervasive infrastructure visibility. It continuously verifies and validates the operational states of the network while proactively detecting any drifts from the operators’ intent, detecting different types of anomalies throughout the network, analyzing the root cause of anomalies, and identifying remediation methods. It modernizes the operation of networks, helping the network team to reduce troubleshooting efforts, increase operation efficiency, and proactively prevent network outages.

●     Cisco Nexus Dashboard Orchestrator: The intersite policy manager, which provides single-pane management that enables you to monitor the health of all interconnected fabrics. It also allows you to define centrally the intersite configurations and policies that can then be pushed to the different Cisco Application Policy Infrastructure Controller (APIC), Cisco Cloud Network Controller, or DCNM fabrics, which in turn deploy them in those fabrics. This provides a high degree of control over when and where to deploy the configurations.

This document describes the features, issues, and limitations for the Cisco Nexus Dashboard and supported services.

Supported upgrade paths

For supported upgrade paths, see the Cisco Nexus Dashboard and Services Deployment and Upgrade Guide, Release 3.2(x).

Changes in behavior

Changes in behavior for Nexus Dashboard

●     Beginning with Nexus Dashboard release 3.2(2m), bugscan no longer detects Active bugs through CLI and device log analysis, but is limited to Susceptible Bug detection using platform and software version information only. This functionality will be re-introduced in a future release.

●     Beginning with ND release 3.2(2), there are updates to the behavior when deploying in Linux KVM (for example, only CLI-based procedures are supported when creating the VMs for the nodes).

For more information, see the "Deploying in Linux KVM (Release 3.2(2) and Later)" chapter in see Cisco Nexus Dashboard and Services Deployment and Upgrade Guide, Release 3.2.x.

Changes in behavior for Orchestrator

●     There are no changes in behavior in this release.

Changes in behavior for Fabric Controller

Common enhancements to all personas

●     Beginning with NDFC release 12.2(3), a behavior change is introduced where SSH host key verification is enforced in NDFC. This is similar to any SSH client behavior where a new key seen is trusted but a new key seen afterwards for a given host causes a key verification failure.

For more information, see the section "Server Settings" in the Overview and Initial Setup of Cisco NDFC.

LAN controller enhancements

●     The security groups feature is now supported on FX, FX2, H, and C9408 switches.

For more information, see Configuring Security for VXLAN EVPN Fabrics.

●     ToR switches in Data Center VXLAN EVPN fabrics will be out of sync with NX-API and SNMP trap configurations pending diffs after you upgrade to NDFC 12.2(2x) or later.

◦    The old behavior: NX-API and SNMP trap host configurations are not generated for ToR switches.

◦    The new behavior: NX-API and SNMP trap host configurations are generated for ToR switches.

●     Beginning with NDFC release 12.2(3), for switches in Classic LAN or External Connectivity Network fabric types, a new Expected config/Generated config toggle switch is available, which displays the NDFC-generated configuration based on the intent in the NDFC policies.

For more information, see the section "Previewing Switches" in Add Switches for LAN Operational Mode.

●     Beginning with NDFC release 12.2(3), when editing a network attachment in a VXLAN fabric on a switch with border or border gateway shown in the Switch Role column, you can also provide comma-separated route targets to import or export at the switch level in the Import Route Target and Export Route Target fields. This is supported for both Nexus 9000 and Catalyst 9000 switches.

For more information, see the section "Network Attachments" in About Fabric Overview for LAN Operational Mode Setups.

●     Beginning with NDFC release 12.2(3), support is available for Type 6 for BGP authentication key encryption type for VXLAN EVPN, Enhanced Classic LAN, and BGP fabrics.

For more information, see:

◦    BGP Fabric

◦    Data Center VXLAN EVPN

◦    Enhanced Classic LAN

●     Beginning with NDFC release 12.2(3), a new Set Allowed Vlan On Leaf-ToR Pairing field is introduced when configuring ToR switches in Data Center VXLAN EVPN fabrics.

For more information, see Configuring ToR Switches.

●     Beginning with NDFC release 12.2(3), a new Freeform tab is introduced when creating or editing these fabric types:

◦    BGP Fabric

◦    Data Center VXLAN EVPN

◦    Enhanced Classic LAN

◦    IPFM and Classic IPFM

●     Beginning with NDFC release 12.2(3), a new VRF Lite tab is introduced when creating or editing VRFs.

For more information, see the “Creating a VRF” section in About Fabric Overview for LAN Operational Mode Setups.

SAN controller enhancements

When contract associations belonging to different VRFs reference the same contract (Filter and Action), the direction gets indirectly converted to policies and filter security CLIs.

VRF creation happens implicitly as part of network creation. This means that VRFs are created and security groups/associations are also created for the VRF referencing the same contract. No switches are attached to the VRF yet. Switches are attached to the network, and NDFC implicitly creates the VRF and the security policies.

The security group/associations are removed for multiple VRFs. When deployment is done from the Networks, Switches, or VRFs page, VRF deployment fails.

A new knob has been introduced on the switch preview side-by-side page for viewing Expected/Generated configurations in Nexus Dashboard Fabric Controller (NDFC) for LAN Classic and External Fabric. The Pending Config option, which is meant to display the same order of commands for the same operation, does not consistently show the correct order in some scenarios.

Specifically:

Incorrect Command Ordering: When there is a config diff (i.e., differences in configurations that need to be pushed), the Generated Config displays the commands in the wrong order. This is especially noticeable when comparing the configuration to the running config output in the same screen. The ordering mismatch can lead to confusion, even though there is no functional impact on the system.

Display Gaps Between Configs: In some cases, there are visible gaps between configuration entries in the display, which further contributes to the confusion. These gaps may appear when comparing the Expected vs. Generated configurations, making it unclear whether there are missing configurations or misalignment in the data.

While the issue does not affect the functionality of the system (i.e., the configuration will still be pushed and applied correctly), it could cause confusion for users who are relying on the previewed config order to verify changes before applying them.

Known issues for Nexus Dashboard

Table 14 Known issues for Nexus Dashboard

Bug ID

Description

CSCwj24254

The issue occurs in the following scenario:

1) During bootstrap, add three nodes

2) Select the NDFC and NDI deployment mode

3) Go back to the previous page and delete two nodes

4) UI does not block bootstrap process afterwards. The API error appears after submitting the bootstrap configuration.

CSCwi08020

On some of the virtual setup we have seen DB we store for prometheus gets full and mond stops working. As a result, UI will fail to poll some of the metrics required for cluster health etc.

CSCvy62110

For Nexus Dashboard nodes connected to Catalyst switches packets are tagged with vlan0 even though no VLAN is specified. This causes no reachability over the data network. In this case, 'switchport voice vlan dot1p' command must be added to the switch interfaces where the nodes are connected.

CSCvw39822

On power cycle system lvm initialization may fail due to a slowness in the disks.

CSCvw48448

Upgrade fails and cluster is in diverged state with one or more nodes on the target version.

CSCvw57953

When the system is being recovered with a clean reboot of all nodes, the admin login password will be reset to the day0 password that is entered during the bootstrap of the cluster.

CSCvw70476

When bringing up ND cluster first time, all three primary nodes need to join Kafka cluster before any primary node can be rebooted. Failing to do so, 2 node cluster doesn't become healthy as Kafka cluster requires 3 nodes to be in Kafka cluster first time.

CSCvx89368

After ND upgrade, there will be still pods belonging to the older version running on the cluster.

CSCvx98282

Pods in pending state for a long period upon restart. These pods are usually stateful sets that require specific node placement and capacity must be available on the specific node they are first scheduled. This happens when multiple applications are installed on the same ND cluster and the ND capacity overloaded.

CSCvu21304

Intersight device connector connects to the Intersight over the Cisco Application Services Engine Out-Of-Band Management.

CSCwe04619

The 'acs health' command may show a service as unhealthy and kubectl (available in the Tech Support collection) shows the service is in ContainerCreateError state.

CSCwd84875

Two Nodes RMA requires manual intervention.

CSCwb31373

After node failover, kubernetes scheduling may be unable to find appropriate resources for the pods in an app.

The symptom is that the app health will not converge and kubectl commands will show unhealthy pods.

CSCwj06781

If GUI-based upgrade workflow fails, the UI error message shows a documentation link for using a manual upgrade as a workaround, but the documentation link points to existing release's content which does not apply to the target release.

CSCwj44955

There may be an issue during the bootstrap process on 3-node vND (ESX) clusters which can cause the 'acs health' command to show the following error:

'k8s: services not in desired state - aaamgr,cisco-intersightdc,eventmonitoring,infra-kafka,kafka,mongodb,sm,statscollect'

CSCwd84563

Upgrade to v2.3 from v2.1.2d - No warning messages to disable old App/containers.

Known issues for Orchestrator

Table 15 Known issues for Orchestrator

Bug ID

Description

CSCwk73141

When upgrading using NDO, the validation of the APIC image upgrade fails with timeout error.

This can happen if the APIC takes more than 90 seconds to respond to the validation request from NDO or if the APIC has lots of faults, which need to be examined during the validation process.

CSCwi64894

Extra contract relationships seen in shadow objects when parent EPG consumes or provides to multiple contracts.

CSCwi12966

Implicit Filters and Contracts are not getting updated when the original policies are modified. Any small property changes in policies is not updating the implicit objects.

CSCvv67993

NDO will not update or delete VRF vzAny configuration which was directly created on APIC even though the VRF is managed by NDO.

CSCvo82001

Unable to download Nexus Dashboard Orchestrator report and debug logs when database and server logs are selected

CSCvn90706

For hybrid cloud deployments, no validation is available for shared services scenarios

CSCvi61260

If an infra L3Out that is being managed by Cisco Multi-Site is modified locally in a Cisco APIC, Cisco Multi-Site might delete the objects not managed by Cisco Multi-Site in the Infra L3Out.

CSCvu71584

Routes are not programmed on CSR and the contract config is not pushed to the Cloud fabric.

CSCvw47022

Shadow of cloud VRF may be unexpectedly created or deleted on the on-premises fabric.

CSCvt47568

Let's say APIC has EPGs with some contract relationships. If this EPG and the relationships are imported into NDO and then the relationship was removed and deployed to APIC, NDO doesn't delete the contract relationship on the APIC.

CSCwa31774

When creating VRFs in infra tenant on a Google Cloud fabric, you may see them classified as internal VRF in NDO. If you then import these VRFs in NDO, the allowed routeleak configuration will be determined based on whether the VRF is used for external connectivity (external VRF) or not (internal VRF).

This is because on cAPIC, VRFs in infra tenant can fall into 3 categories: internal, external and un-decided.

NDO treats infra tenant VRFs as 2 categories for simplicity: internal and external.

There is no usecase impacted because of this.

CSCwa47934

Removing fabric connectivity or changing the protocol is not allowed between two fabrics.

CSCwa52287

Template goes to approved state when the number of approvals is fewer than the required number of approvers.

CSCvy31532

After a fabric is re-registered, NDO may have connectivity issues with APIC or CAPIC

CSCwc62636

If cloud fabrics have EVPN-based connectivity with another cloud or on-premises fabric, then contract-based routing must be enabled for intersite traffic to work.

CSCwc59208

When APIC-owned L3Outs are deleted manually on APIC by the user, stretched and shadow InstP belonging to the L3Outs get deleted as expected. However, when deploying the template from NDO, only the stretched InstPs detected in config drift will get deployed.

CSCvz07639

NSG rules on Cloud EPG are removed right after applying service graph between Cloud EPG and on-premises EPG, which breaks communication between Cloud and on-premises.

CSCwa26712

Existing IPSec tunnel state may be affected after update of connectivity configuration with external device.

CSCwa40878

User can not withdraw the hubnetwork from a region if intersite connectivity is deployed.

CSCwa17852

BGP sessions from Google Cloud fabric to AWS/Azure fabric may be down due to CSRs being configured with a wrong ASN number.

CSCwi19857

APIC has GOTO and GOTHROUGH options when configuring an L3 device, but in NDO the GOTHROGH option is not exposed intentionally. Only the GOTO option is supported.

CSCwi95494

May be unable to deploy a template with VPCI after modifying Node 1 and Node 2.

NDO will not delete a VPC peer group on APIC, because it may be shared by multiple other VPCs that are not managed by NDO, removing which may cause config issues.

CSCwi35916

After an upgrade to NDO 4.2.1 or later, the orchestrator raises configuration drifts that are not automatically reconciled, associated to the configuration objects for Service Devices and Service Graphs.

N/A

The ipDPLearning configuration under EPG and BD subnets is available as an option through the NDO 4.4.3 REST API but is not supported.
