Network 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 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 3. Open Bugs—Open Bugs—HA

Bug Identifier

Headline

CSCvm33809

Three-node HA: The device remains in onboarding state even after the image upgrade succeeds.

CSCvm92516

After master node is down in a three-node setup, several pipeline get into restarting state.

CSCvn32215

In a three-node setup, if you bring down the node while LAN automation is in progress, the LAN automation status shows as complete, yet without success.

This problem occurs if you perform a network-orchestration service restart or a full node restart while LAN automation is in progress.

The network orchestration service doesn't resume the ongoing LAN automation session. It marks LAN automation as complete and releases all IP addresses allocated from IPAM. Users are expected to perform a configuration cleanup on the seed and write-erase/reload discovered devices and start a new LAN automation session.

CSCvn64113

External clients (such as Cisco ISE, network devices, and so on) can no longer communicate with Cisco DNA Center.

This behavior occurs when you change one or more of the virtual IP addresses used by your Cisco DNA Center deployment.

CSCvn32554

A wireless controller goes into unmonitored state after a restore from the backup.

CSCvn42568

After vNICs are deleted from vNFS, interfaces and configurations aren't deleted.

CSCvn46294

The Assurance Sensor-Driven Test interface allows a single sensor to be used in multiple test suites, of which each test suite can have one or more tests. Each suite has a defined recurring interval at which the tests within the suite are scheduled to run. If a sensor is overloaded by the number of tests within a single suite or is used across multiple suites containing multiple tests, a scenario occurs where the sensor cannot complete the suite tests within the defined recurring interval. When this occurs, gaps are seen in the 24-hour test results.

CSCvn54563

Images loaded through Plug and Play show in newly added sites and in all sites.

CSCvn75941

Resolved Bugs

The following table lists the resolved bugs in Cisco DNA Center, Release 1.2.12.2.

Table 5. Resolved Bugs for Cisco DNA Center, Release 1.2.12.2

Bug Identifier

Headline

CSCvr03768

The WSDL certificate in Cisco DNA Center's EJBCA Public Key Infrastructure (PKI) broker service expired on October 4, 2019. After this server certificate expires, Cisco DNA Center clients that use the EJBCA service for secure sessions fail to connect. As a result, Cisco DNA Center fails to onboard the Embedded Wireless Controller on Cisco Catalyst 9800 series devices and 1800s wireless sensors. Apart from the eWLC, there is no impact to any other WLC, switch, or router onboarding, or any other feature in Cisco DNA Center.

There is no workaround for this problem. You must upgrade Cisco DNA Center to a version that has been patched to include a new WSDL certificate. The following Cisco DNA Center releases have the fix with the new WSDL certificate: 1.2.10.5, 1.2.12.2, 1.3.0.4, and 1.3.1.1. The new certificate has a 20-year expiry.

Limitations and Restrictions

Backup and Restore Limitations

Backup and restore limitations and restrictions include:

  • 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.

HA Limitation

In this release, Cisco DNA Center provides HA support only for Automation and Cisco SD-Access. HA for Assurance is not supported.

Cisco ISE Integration Limitations

Cisco ISE integration limitations and restrictions include:

  • 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 subordinate CA of a root CA, the certificate chain uploaded to Cisco DNA Center while replacing the Cisco DNA Center certificate must contain all three certificates.

  • Self-signed certificates applied to 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.

  • For automation integration, the Cisco ISE internal certificate authority must issue the pxGrid certificate for Cisco DNA Center.

Brownfield Feature-Related Limitations

Brownfield feature-related limitations include:

  • 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 groups with the SSID are associated with the same interfaces.

  • 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, the error "Policy Deployment failed" is displayed.

Cisco Plug and Play Limitations

Plug and Play limitations and restrictions include:

  • 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 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>

LAN Automation Limitation

Cisco Catalyst 9500 high-performance switches (including C9500-32C, C9500-32QC, C9500-24Y4C, C9500-48Y4C) are not supported as seed devices and PnP agents for LAN automation. If you try to use a Catalyst 9500H as the seed device, the GUI displays the following error:

Failed to create LAN Automation session. BAD_Request:
[Common Settings - Please change the discovery interface configuration to L2 mode and then re-sync the primary device from Inventory App].
