Table 8. New and Changed Software Features in Cisco Software-Defined Access
Feature Description

Support for VLAN ID customization

You can now assign a desired VLAN ID to a host pool VLAN and Layer 3 handoff VLAN. The VLAN IDs can be in the range of 1 to 4095.

This feature provides more flexibility in segment creation for the brownfield SD-Access deployments. Delete any existing overlapping or conflicting VLANs or SVIs or AAA configurations from the device and resynchronize the device in the inventory prior to adding it to the SD-Access fabric.

When you upgrade from an earlier release, the existing VLANs continue to work normally. Post upgrade, you will need to provide an external VLAN ID for new Layer 3 handoffs. Layer 2 Handoff VLAN is auto populated based on the VLAN ID assigned to the host pool. You can edit the Layer 2 Handoff VLAN ID to assign a different VLAN number.

To change the VLAN ID for an existing IP pool VLAN, delete the IP pool and create the IP pool again with the desired VLAN ID.

Consider the following guidelines before assigning a custom VLAN ID:

  • If you do not provide a custom VLAN ID, Cisco DNA Center generates a VLAN ID in the range of 1021 to 2020.

  • VLAN IDs 1, 1002-1005, 2046, 4095 are reserved and cannot be used.

  • Critical voice or pre-auth VLAN is assigned a VLAN ID of 2046 and cannot be changed.

  • Borders in the same site or in different sites can share the same Layer 3 handoff VLAN IDs.

Fabric edge node scale

The number of local endpoints that an SD-Access fabric edge node supports is now enhanced. The support is limited to the capability of the platform that is configured as the fabric edge.

Use the show lisp platform command to check the platform limits.

See the Cisco DNA Center Data Sheet for specific scale numbers.

Table 9. New Features in Cisco Group-Based Policy Analytics
Feature Description

View and Modify Access Contracts

Access Contracts can now be created and modified directly from the Analytics tab. You can view, create, edit, and delete access contracts from the Analytics tab directly.

Deprecated Features

SNMPv3 Data Encryption Standard (DES) Privacy Mode support is deprecated in Cisco DNA Center 2.2.2. SNMPv3 DES is no longer supported in Cisco DNA Center 2.2.2 or any later releases.

SNMPv3 DES is used to ensure data confidentiality, where the designated portion of an SNMP message is encrypted and included as part of the message sent to the recipient. DES is no longer considered secure due to its too-short key length and its proven ineffectiveness against brute force attacks. Advanced Encryption Standard (AES) is the recommended privacy mode.

Cisco DNA Center-Supported Devices

Cisco DNA Center supports Cisco Connected Mobile Experiences (CMX) 10.6.2. Earlier versions of CMX are not supported.


Note

While configuring the CMX settings, do not include the # symbol in the CMX admin password. The CMX integration fails if you include the # symbol in the CMX admin password.


Plug and Play Considerations

Plug and Play Support

General Feature Support

Plug and Play supports the following features, depending on the Cisco IOS software release on the device:

  • AAA device credential support: The AAA credentials are passed to the device securely and the password is not logged. This feature allows provisioning a device with a configuration that contains aaa authorization commands. This feature requires software release Cisco IOS 15.2(6)E1, Cisco IOS 15.6(3)M1, Cisco IOS XE 16.3.2, or Cisco IOS XE 16.4 or later on the device.

  • Image install and upgrade for Cisco Catalyst 9200 Series, Catalyst 9300 Series, Catalyst 9400 Series, Catalyst 9500 Series, Catalyst 3650 Series, and Catalyst 3850 Series switches are supported only when the switch is booted in install mode. (Image install and upgrade is not supported for switches booted in bundle mode.)

Secure Unique Device Identifier Support

The Secure Unique Device Identifier (SUDI) feature that allows secure device authentication is available on the following platforms:

  • Cisco routers:

    • Cisco ISR 1100 Series with software release 16.6.2

    • Cisco ISR 4000 Series with software release 3.16.1 or later, except for the ISR 4221, which requires release 16.4.1 or later

    • Cisco ASR 1000 Series (except for the ASR 1002-x) with software release 16.6.1

  • Cisco switches:

    • Cisco Catalyst 3850 Series with software release 3.6.3E or 16.1.2E or later

    • Cisco Catalyst 3650 Series and 4500 Series with Supervisor 7-E/8-E, with software release 3.6.3E, 3.7.3E, or 16.1.2E or later

    • Cisco Catalyst 4500 Series with Supervisor 8L-E with software release 3.8.1E or later

    • Cisco Catalyst 4500 Series with Supervisor 9-E with software release 3.10.0E or later

    • Cisco Catalyst 9300 Series with software release 16.6.1 or later

    • Cisco Catalyst 9400 Series with software release 16.6.1 or later

    • Cisco Catalyst 9500 Series with software release 16.6.1 or later

    • Cisco Catalyst IE3300 Series with software release 16.10.1e or later

    • Cisco Catalyst IE3400 Series with software release 16.11.1a or later

  • NFVIS platforms:

    • Cisco ENCS 5400 Series with software release 3.7.1 or later

    • Cisco ENCS 5104 with software release 3.7.1 or later


Note

Devices that support SUDI have two serial numbers: the chassis serial number and the SUDI serial number (called the License SN on the device label). You must enter the SUDI serial number in the Serial Number field when adding a device that uses SUDI authentication. The following device models have a SUDI serial number that is different from the chassis serial number:

  • Cisco routers: Cisco ISR 43xx, Cisco ISR 44xx, Cisco ASR1001-X/HX, Cisco ASR1002-HX

  • Cisco switches: Cisco Catalyst 4500 Series with Supervisor 8-E/8L-E/9-E, Catalyst 9400 Series


Management Interface VRF Support

Plug and Play operates over the device management interface on the following platforms:

  • Cisco routers:

    • Cisco ASR 1000 Series with software release 16.3.2 or later

    • Cisco ISR 4000 Series with software release 16.3.2 or later

  • Cisco switches:

    • Cisco Catalyst 3650 Series and 3850 Series with software release 16.6.1 or later

    • Cisco Catalyst 9300 Series with software release 16.6.1 or later

    • Cisco Catalyst 9400 Series with software release 16.6.1 or later

    • Cisco Catalyst 9500 Series with software release 16.6.1 or later

4G Interface Support

Plug and Play operates over a 4G network interface module on the following Cisco routers:

  • Cisco 1100 Series ISR with software release 16.6.2 or later

Configure Server Identity

To ensure successful Cisco DNA Center discovery by Cisco devices, the server SSL certificate offered by Cisco DNA Center during the SSL handshake must contain an appropriate Subject Alternate Name (SAN) value so that the Cisco Plug and Play IOS Agent can verify the server identity. This may require the administrator to upload a new server SSL certificate, which has the appropriate SAN values, to Cisco DNA Center.

The SAN requirement applies to devices running the following Cisco IOS releases:

  • Cisco IOS Release 15.2(6)E2 and later

  • Cisco IOS Release 15.6(3)M4 and later

  • Cisco IOS Release 15.7(3)M2 and later

  • Cisco IOS XE Denali 16.3.6 and later

  • Cisco IOS XE Everest 16.5.3 and later

  • Cisco IOS Everest 16.6.3 and later

  • All Cisco IOS releases from 16.7.1 and later

The value of the SAN field in the Cisco DNA Center certificate must be set according to the type of discovery being used by devices, as follows:

  • For DHCP option-43 or option-17 discovery using an explicit IPv4 or IPv6 address, set the SAN field to the specific IPv4 or IPv6 address of Cisco DNA Center.

  • For DHCP option-43 or option-17 discovery using a hostname, set the SAN field to the Cisco DNA Center hostname.

  • For DNS discovery, set the SAN field to the plug and play hostname, in the format pnpserver.domain.

  • For Cisco Plug and Play Connect cloud portal discovery, set the SAN field to the Cisco DNA Center IP address if the IP address is used in the Plug and Play Connect profile. If the profile uses the Cisco DNA Center hostname, the SAN field must be set to the FQDN of the controller.

If the Cisco DNA Center IP address that is used in the Plug and Play profile is a public IP address that is assigned by a NAT router, this public IP address must be included in the SAN field of the server certificate.

If an HTTP proxy server is used between the devices and Cisco DNA Center, ensure that the proxy certificate has the same SAN fields with the appropriate IP address or hostname.

We recommend that you include multiple SAN values in the certificate, in case discovery methods vary. For example, you can include both the Cisco DNA Center FQDN and IP address (or NAT IP address) in the SAN field. If you do include both, set the FQDN as the first SAN value, followed by the IP address.

If the SAN field in the Cisco DNA Center certificate does not contain the appropriate value, the device cannot successfully complete the plug and play process.


Note

The Cisco Plug and Play IOS Agent checks only the certificate SAN field for the server identity. It does not check the common name (CN) field.

Table 10. Open Bugs
Bug Identifier Headline

CSCvw61097

Under Policy > Group-Based Access Control > Manage Views, when you duplicate a custom view, the new (duplicate) is created with the string "_Copy" appended to the original view name. If you then try to duplicate a given view (with a given name) more than once, and you didn't previously edit and rename the original duplicate, an error message states that the new view cannot be created because the name already exists. Note that this is expected behavior, similar to what may be observed when creating new views.

CSCvx19662

The following behavior is seen on Cisco DNA Center 2.2.2 with the Cisco Wide Area Bonjour application and the Wide Area Bonjour patch:

  1. The switch running config is visible in Cisco DNA Center for a switch added to Inventory with Priv 1 user and NETCONF if that switch was also added with the enable password. Because the user has Privilege 1 credentials in the switch, the running config should not be visible. However, it is visible.

  2. After the switch is added, even if you remove the enable password and update the switch in the Inventory, the behavior remains unchanged; you can still view the running configuration.

CSCvx51633

Searching for a specific rule in Endpoint Analytics rules pages might take longer than 10 seconds.

CSCvx66625

In a Cisco DNA Center environment with large numbers of endpoints (around 200,000), if you try to perform a Global search for MAC/IP address and go to Endpoint Analytics, it might take around 10 seconds to see the Endpoint Details page.

CSCvx69133

Disaster recovery system status stuck in registering and recovery site stuck in connecting to main site during register.

CSCvx75691

CSCvx90914

Image import fails with the following errors:

Unable to download the image from cisco.com.
The remote server presented an untrusted or expired certificate. Please verify the certificate.

CSCvx95166

For Cisco Catalyst 9000 switches, LAN automation coupled with SWIM deletes the current running software packages, as well as older packages, during a software image upgrade. In contrast, performing SWIM by itself does not delete the current software packages.

CSCvy08147

The route text box in the config-wizard has a limitation of 1024 characters. If the number of static routes exceed that number of characters, then the config-wizard will crash.

CSCvy15212

Cisco Wide Area Bonjour: On powering up from Cisco IMC, a single-node cluster does not come up after several hours. While coming up, several pods go into Error State while waiting for the GlusterFS mount point. Remedyctl starts to recover, but fails because the maglevserver pod is down.

CSCvy21115

For the Cisco DNA Center Application Hosting service, when you update a newer application version on top of an existing application version, the application name on the new version must match the existing application name. If the application names (from the package descriptor file) don’t match, the Application Hosting service rejects the Update operation.

CSCvy23774

A user with a Super Admin role cannot see notifications from the Notification Center. Also, changes made by a user with an Admin role don't persist.

CSCvy42676

After a successful upgrade from Cisco DNA Center 2.1.2.3 to 2.2.2.1, all users other than the Admin user see the following error on the Software Updates page:

Connectivity check failed. Unable to locate new system updates. An error occurred while checking connectivity.
Cannot locate new updates. Retry.

With the Admin login, there is no error. The page accurately shows "Your system package is up to date."

CSCvy45589

Bug Identifier Headline

CSCvx89202

In the External Authentication page > AAA Server(s) area, the Shared Secret field is missing text or string information.

In Cisco DNA Center 1.3.3.9, the Shared Secret field shows descriptive text for the required value. If the value is empty, additional text is displayed under the "Shared secret must not be empty" line.

However, in Cisco DNA Center 2.2.2.0, the following problems occur:

  • The shared secret is not displayed when empty, so it's unclear what the field is used for.

  • When the Shared Secret field contains a value, nothing is displayed. In earlier releases, a string such as " ****** " was displayed to show that a value was configured.

  • When you click Show to see if there is a value configured, nothing is displayed. If a value is already configured, there is no indicator.

CSCvx92936

Under the My Profile and Settings page, a change to the first name does not take effect.

CSCvx97127

When the Notification Center is enabled for License notification, Assurance issue notifications are reported along with the license notifications. While there is no functional impact, notifications become a bit noisy based on the amount of network issues that Cisco DNA Center detects. Also, the Assurance issues don't provide any details when you click the notifications.

This problem occurs when you enable notifications for licensing issues (Notification Center > Settings > Notification Preferences > Know Your Network > Devices).

CSCvx99671

In the Workflows GUI, when text in an "In Progress" tile is long or impedes other elements in the tile, the text should be truncated or abbreviated.

Limitations and Restrictions

Upgrade Limitation

If you are upgrading to Cisco DNA Center and all of the following conditions apply, the upgrade never starts:

  • Cisco ISE is already configured in Cisco DNA Center.

  • The version of Cisco ISE is not 2.6 patch 1 or 2.4 patch 7 or later.

  • Cisco DNA Center contains an existing fabric site.

  • The number of DNS servers must not exceed three.

Although the UI does not indicate that the upgrade failed to start, the logs contain messages related to the upgrade failure.

To work around this problem, upgrade Cisco ISE to 2.6 patch 1 or 2.4 patch 7 or later, and retry the Cisco DNA Center upgrade.

Backup and Restore Limitations

  • You cannot take a backup of one version of Cisco DNA Center and restore it to another version of Cisco DNA Center. You can only restore a backup to an appliance that is running the same Cisco DNA Center software version, applications, and application versions as the appliance and applications from which the backup was taken.

  • After performing a restore operation, update your integration of Cisco ISE with Cisco DNA Center. After a restore operation, Cisco ISE and Cisco DNA Center might not be in sync. To update your Cisco ISE integration with Cisco DNA Center, choose System Settings > Settings > Authentication and Policy Servers. Choose Edit for the server. Enter your Cisco ISE password to update.

  • After performing a restore operation, the configuration of devices in the network might not be in sync with the restored database. In such a scenario, you should manually revert the CLI commands pushed for authentication, authorization, and accounting (AAA) and configuration on the network devices. Refer to the individual network device documentation for information about the CLI commands to enter.

  • Re-enter the device credentials in the restored database. If you updated the site-level credentials before the database restore, and the backup that is being restored does not have the credential change information, all the devices go to partial-collection after restore. You must then manually update the device credentials on the devices for synchronization with Cisco DNA Center, or perform a rediscovery of those devices to learn the device credentials.

  • Perform AAA provisioning only after adjusting network device differential changes to the restored database. Otherwise, device lockouts might occur.

  • You can back up and restore Automation data only or both Automation and Assurance data. But you cannot use the GUI or the CLI to back up or restore only Assurance data.

Cisco ISE Integration Limitations

  • ECDSA keys are not supported as either SSH keys for Cisco ISE SSH access, or in certificates in Cisco DNA Center and Cisco ISE.

  • Full certificate chains must be uploaded to Cisco DNA Center while replacing an existing certificate. If a Cisco DNA Center certificate is issued by a subCA of a rootCA, the certificate chain uploaded to Cisco DNA Center while replacing the Cisco DNA Center certificate must contain all three certificates.

  • Self-signed certificates applied on Cisco DNA Center must have the Basic Constraints extension with cA:TRUE (RFC5280 section-4.2.19).

  • The IP address or FQDN of both Cisco ISE and Cisco DNA Center must be present in either the Subject Name field or the Subject Alt Name field of the corresponding certificates.

  • If a certificate is replaced or renewed in either Cisco ISE or Cisco DNA Center, trust must be re-established.

  • The Cisco DNA Center and Cisco ISE IP or FQDN must be present in the proxy exceptions list if there is a web proxy between Cisco DNA Center and Cisco ISE.

  • Cisco DNA Center and Cisco ISE nodes cannot be behind a NAT device.

  • Cisco DNA Center and Cisco ISE cannot integrate if the ISE Admin and ISE pxGrid certificates are issued by different enterprise certificate authorities.

    Specifically, if the ISE Admin certificate is issued by CA server A, the ISE pxGrid certificate is issued by CA server B, and the pxGrid persona is running on a node other than ISE PPAN, the pxGrid session from Cisco DNA Center to Cisco ISE does not work.

  • The Cisco ISE internal certificate authority must issue the pxGrid certificate for Cisco DNA Center.

License Limitation

The Cisco DNA Center License Manager supports Smart Licensing only for wireless LAN controller models that run Cisco IOS XE. License Manager does not support wireless LAN controller models that run Cisco AireOS.

Fabric Limitations

  • Cisco DNA Center supports up to a maximum of 1.2 million interfaces on fabric devices. Fabric interfaces include physical and virtual interfaces like switched virtual interfaces, loopback interfaces, and so on.

    Physical ports cannot exceed 480,000 ports on a 112-core appliance.

  • IP address pools reserved at the area level are shown as inherited at the building level on the Design > Network Settings > IP Address Pools window; however, these IP address pools are not listed on the Host Onboarding window if the fabric site is defined at the building level. If the fabric site is defined at the building level, you must reserve the IP address pools at the building level; if the fabric site is defined at the area level, you must reserve the IP address pools at the area level.

    To work around this issue, release and reserve the IP address pool at the same level (area or building) as the fabric site, or reconfigure the fabric site at the same level as the reserved IP address pool.

  • Cisco DNA Center does not support multicast across multiple fabric sites that are connected by an SDA transit network.

  • In a fabric setup with Cisco Catalyst 9800 HA devices, if one of the HA devices goes down, you must complete the following steps to replace it:

    1. From the Cisco DNA Center Inventory window, resynchronize the HA device that failed. Cisco DNA Center shows the device as standalone; the standby has failed and has been removed.

    2. Set the priority for the devices. If you want the existing device to return as the active device after forming HA with the new device, ensure that the HA priority of the existing device is set to 2 (or the highest available priority value). You configure the device priority from the web UI, under Administration > Device > Redundancy. Alternatively, you can enter the following CLI command to configure the device priority:

      chassis <chassis_number> priority 2

      To view the chassis number and the current priority value, enter the show chassis EXEC command.

      If the priority is set to the default value of 1 on both devices, the device with the lower MAC address becomes the active device.

    3. Configure the chassis redundancy command on the new device using the same local and remote IP addresses that were used on the failed device. You configure the chassis redundancy in either the web UI or the CLI.

    4. Reboot both devices to form the HA pair.

    5. After HA is up, resynchronize the devices in Cisco DNA Center. The Inventory window shows the new HA pair. Verify the serial numbers in the Serial Number column. For an HA pair, both the active and standby serial numbers are shown.

Brownfield Feature-Related Limitations

  • Cisco DNA Center cannot learn device credentials.

  • You must enter the preshared key (PSK) or shared secret for the AAA server as part of the import flow.

  • Cisco DNA Center does not learn the details about DNS, WebAuth redirect URL, and syslog.

  • Cisco DNA Center can learn only one wireless controller at a time.

  • For site profile creation, only the AP groups with AP and SSID entries are considered.

  • Automatic site assignment is not possible.

  • SSIDs with an unsupported security type and radio policy are discarded.

  • For authentication and accounting servers, if the RADIUS server is present in the device, it is given first preference. If the RADIUS server is not present, the TACACS server is considered for design.

  • The Cisco ISE server (AAA) configuration is not learned through brownfield provisioning.

  • The authentication and accounting servers must have the same IP addresses for them to be learned through brownfield provisioning.

  • When an SSID is associated with different interfaces in different AP groups, during provisioning, the newly created AP group with the SSID is associated with the same interface.

  • A wireless conflict is based only on the SSID name, and does not consider other attributes.

Wireless Policy Limitation

If an AP is migrated after a policy is created, you must manually edit the policy and point the policy to an appropriate AP location before deploying the policy. Otherwise, Policy Deployment failed is displayed.

AP Limitations

  • AP as a sensor is not supported in this release of Cisco DNA Center.

  • Configuring APs in FlexConnect mode before provisioning the locally switched WLANs bypasses the AP provisioning error. Otherwise, the AP provisioning fails when the locally switched WLANs are provisioned on the wireless controller or APs through Cisco DNA Center.

    After the provisioning failure, the AP rejoins the wireless controller. You can reprovision the AP for a successful provisioning.

  • Provisioning of 100 APs takes longer in this release as compared to 3 minutes in earlier releases. The amount of time varies depending on the "wr mem" time of the Cisco Catalyst 9800 Series Controller, which includes Cisco Catalyst 9800-40 Wireless Controller, Cisco Catalyst 9800-80 Wireless Controller, and Cisco Catalyst 9800-CL Cloud Wireless Controller devices.

Inter-Release Controller Mobility (IRCM) Limitation

The interface or VLAN configuration is not differentiated between foreign and anchor controllers. The VLAN or interface that is provided in Cisco DNA Center is configured on both foreign and anchor controllers.

IP Device Tracking on Trunk Port Limitation

Rogue-on-wire detection is impacted; Cisco DNA Center does not show all clients connected to a switch via an access point in bridge mode. The trunk port is used to exchange all VLAN information. When you enable IP device tracking on the trunk port, clients connected on the neighbor switch are also shown. Cisco DNA Center does not collect client data if the connected interface is a trunk port and the neighbor is a switch. As a best practice, disable IP device tracking on the trunk port. The rogue-on-wire is not detected if the IP device tracking is enabled on the trunk port. See Disabling IP Device Tracking for more information.

IP Address Manager Limitations

  • Cisco DNA Center supports integration with an external IPAM server that has trusted certificates. In the Cisco DNA Center GUI, under System > Settings > External Services > IP Address Manager, you might see the following error:

    NCIP10282: Unable to find the valid certification path to the requested target.

    To correct this error for a self-signed certificate:

    1. Using OpenSSL, enter one of the following commands to download the self-signed certificate, depending on your IPAM type. (You can specify the FQDN [domain name] or IP address in the command.)

      openssl s_client -showcerts -connect Infoblox-FQDN:443
      openssl s_client -showcerts -connect Bluecat-FQDN:443
    2. From the output, use the content from ---BEGIN CERTIFICATE--- to ---END CERTIFICATE--- to create a new .pem file.

    3. Go to System > Settings > Trust & Privacy > Trustpool, click Import, and upload the certificate (.pem file).

    4. Go to System > Settings > External Services > IP Address Manager and configure the external IPAM server. (If the IPAM server is already configured, skip this step.)

    To correct this error for a CA-signed certificate, install the root certificate and any intermediate certificates of the CA that is installed on the IPAM into the Cisco DNA Center trustpool (System > Settings > Trust & Privacy > Trustpool).

  • You might see the following error if a CA-signed certificate is revoked by the certificate authority:

    NCIP10286: The remote server presented with a revoked certificate. Please verify the certificate.

    To correct this, obtain a new certificate from the certificate authority and upload it to System > Settings > Trust & Privacy > Trustpool.

  • You might see the following error after configuring the external IPAM details:

    IPAM external sync failed:
    NCIP10264: Non Empty DNAC parent pool <CIDR> exists in external ipam.

    To correct this, log in to the external IPAM server (such as BlueCat). Confirm that the parent pool CIDR exists in the external IPAM server, and remove all the child pools that are configured under that parent pool. Then, return to the Cisco DNA Center GUI and reconfigure the IPAM server under System > Settings > External Services > IP Address Manager.

  • You might see the following error while using IP Address Manager to configure an external IPAM:

    NCIP10114: I/O error on GET request for "https://<IP>/wapi/v1.2/":
    Host name '<IP>' does not match the certificate subject provided by the peer
    (CN=www.infoblox.com, OU=Engineering, O=Infoblox, L=Sunnyvale, ST=California, C=US);
    nested exception is javax.net.ssl.SSLPeerUnverifiedException: Host name '<IP>'
    does not match the certificate subject provided by the peer (CN=www.infoblox.com, OU=Engineering,
    O=Infoblox, L=Sunnyvale, ST=California, C=US) |

    To correct this, log in to the external IPAM server (such as Infoblox) and regenerate your external IPAM certificate with the common name (CN) value as the valid hostname or IP address. In the preceding example, the CN value is www.infoblox.com, which is not the valid hostname or IP address of the external IPAM.

    After you regenerate the certificate with a valid CN value, go to System > Settings > Trust & Privacy > Trustpool. Click Import and upload the new certificate (.pem file).

    Then, go to System > Settings > External Services > IP Address Manager and configure the external IPAM server with the server URL as the valid hostname or IP address (as listed as the CN value in the certificate).

IPv6 Limitations

If you choose to run Cisco DNA Center in IPv6 mode:

  • Access Control Application, Group-Based Policy Analytics, and Cisco AI Endpoint Analytics packages are disabled and cannot be downloaded or installed.

  • Communication through Cisco ISE pxGrid is disabled, because Cisco ISE pxGrid does not support IPv6.

Cisco Plug and Play Limitations

  • Virtual Switching System (VSS) is not supported.

  • The Cisco Plug and Play Mobile app is not supported with Plug and Play in Cisco DNA Center.

  • The Stack License workflow task is supported for Cisco Catalyst 3650 and 3850 Series switches running Cisco IOS XE 16.7.1 and later.

  • The Plug and Play agent on the switch is initiated on VLAN 1 by default. Most deployments recommend that VLAN 1 be disabled. If you do not want to use VLAN 1 when PnP starts, enter the following command on the upstream device:

    pnp startup-vlan <vlan_number>

Cisco Group-Based Policy Analytics Limitations

  • Cisco Group-Based Policy Analytics supports up to five concurrent requests based on realistic customer data. While it is desirable for GUI operations to respond within 5 seconds or less, for extreme cases based on realistic data, it can take up to 20 seconds. There is no mechanism to prevent more than five simultaneous requests at a time, but if it does happen, it might cause some GUI operations to fail. Operations that take longer than 1 minute will time out.

  • Data aggregation occurs at hourly offsets from UTC in Cisco Group-Based Policy Analytics. However, some time zones are at a 30-minute or 45-minute offset from UTC. If the Cisco DNA Center server is located in a time zone with a 30-minute or 45-minute offset from UTC and the client is located in a time zone with an hourly offset from UTC, or vice versa, the time ranges for data aggregation in Cisco Group-Based Policy Analytics are incorrect for the client.

    For example, assume that the Cisco DNA Center server is located in California PDT (UTC-7) where data aggregations occur at hourly offsets (8:00 a.m., 9:00 a.m., 10:00 a.m., and so on). When a client located in India IST (UTC+5.30) wants to see the data between 10:00 - 11:00 p.m. IST, which corresponds to the time range 9:30 - 10:30 a.m. PDT in California, no aggregations are seen.

  • Group changes that occur within an hour are not captured. When an endpoint changes from one scalable group to another, Cisco Group-Based Policy Analytics is unaware of this change until the next hour.

  • You cannot sort the Scalable Group and Stealthwatch Host Group columns in the Search Results window.

  • You might see discrepancies in the information related to Network Access Device (including location) between Cisco DNA Assurance and Cisco Group-Based Policy Analytics.

Application Telemetry Limitation

When configuring application telemetry on a device, Cisco DNA Center might choose the wrong interface as the source for NetFlow data.

To force Cisco DNA Center to choose a specific interface, add netflow-source in the description of the interface. You can use a special character followed by a space after netflow-source , but not before it. For example, the following syntax is valid:

netflow-source
MANAGEMENT netflow-source
MANAGEMENTnetflow-source
netflow-source MANAGEMENT
netflow-sourceMANAGEMENT
netflow-source & MANAGEMENT
netflow-source |MANAGEMENT

The following syntax is invalid:

MANAGEMENT | netflow-source
* netflow-source
netflow-source|MANAGEMENT
