Adding Other Assets as Data Sources

Telemetry collection has been extended to devices not managed by the Cisco DNA Center, enabling customers to view and interact with telemetry-derived insights and analytics for a broader range of devices. After the initial CX Cloud Agent setup, users have the option to configure CX Cloud Agent to connect to 20 additional Cisco DNA Centers within the infrastructure monitored by CX Cloud. 

Users can identify devices to incorporate into CX Cloud by uniquely identifying such devices using a seed file or by specifying an IP range, which can be scanned by CX Cloud Agent. Both approaches rely on Simple Network Management Protocol (SNMP) for the purpose of discovery (SNMP) and on Secure Shell (SSH) for connectivity. These must be properly configured to enable successful telemetry collection.

To add other assets as data sources:

• Upload a seed file using a seed file template.
• Provide an IP address range.

Discovery Protocols

Both seed file-based direct device discovery and IP range-based discovery rely on SNMP as the discovery protocol. Different versions of SNMP exist, but CX Cloud Agent supports SNMPV2c and SNMP V3 and either or both versions can be configured. The same information, described next in complete detail, must be provided by the user to complete configuration and to enable connectivity between the SNMP-managed device and SNMP service manager.

SNMPV2c and SNMPV3 differ in terms of security and remote configuration model. SNMPV3 uses an enhanced cryptographic security system supporting SHA encryption to authenticate messages and ensure their privacy. It is recommended that SNMPv3 be used on all public and internet-facing networks to protect against security risks and threats. On CX Cloud, it is preferred that SNMPv3 be configured and not SNMPv2c, except for older legacy devices that lack built-in support for SNMPv3. If both versions of SNMP are configured by the user, CX Cloud Agent can, by default, attempt to communicate with each respective device using SNMPv3 and revert to SNMPv2c if the communication cannot be successfully negotiated.

Connectivity Protocols

As part of the direct device connectivity setup, users must specify details of the device connectivity protocol: SSH (or, alternatively, telnet). SSHv2 can be used, except in the cases of individual legacy assets which lack the appropriate built-in support. Be aware that SSHv1 protocol contains fundamental vulnerabilities. Absent additional security, telemetry data and the underlying assets can be compromised due to these vulnerabilities when relying on SSHv1. Telnet is also insecure. Credential information (usernames and passwords) submitted through telnet are not encrypted and therefore vulnerable to compromise, absent additional security.

Telemtery Processing Limitation for Devices

The following are limitations when processing telemetry data for devices:

• Some devices may show as reachable in the Collection Summary but are not visible in the CX Cloud Assets page. Device instrumentation limitations prevent the processing of such devices telemetry.
• If a device from the seed file or IP range collections is also part of the Cisco DNA Center inventory, the device is reported only once for the Cisco DNA Center entry. The respective devices within the seed file/IP range entry are skipped to avoid duplication.

Adding Other Assets Using a Seed File

A seed file is a .csv file where each line represents a system data record. In a seed file, every seed file record corresponds to a unique device from which telemetry can be collected by CX Cloud Agent. All error or information messages for each device entry from the seed file being imported are captured as part of job log details. All devices in a seed file are considered managed devices, even if the devices are unreachable at the time of initial configuration. In the event a new seed file is being uploaded to replace a previous one, the date of last upload is displayed in CX Cloud.

CX Cloud Agent can attempt to connect to the devices but cannot be able to process each one to show in the Assets pages in cases where it is not able to determine the PIDs or Serial Numbers.Any row in the seed file that starts with a semicolon is ignored. The header row in the seed file starts with a semicolon and can be kept as is (recommended option) or deleted while creating the customer seed file.

It is important that the format of the sample seed file, including column headers, not be altered in any way. Click the link provided to view a seed file in PDF format. This PDF is for reference only and can be used to create a seed file that needs to be saved in .csv format.

Click this link to view a seed file that can be used to create a seed file in .csv format.

Note: This PDF is for reference only and can be used to create a seed file that needs to be saved in .csv format.

This table identifies all necessary seed file columns and the data that must be included in each column.

Seed File Column	Column Header / Identifier	Purpose of the Column
A	IP Address or hostname	Provide a valid, unique IP Address or hostname of the device.
B	SNMP protocol version	The SNMP protocol is required by CX Cloud Agent and is used for device discovery within the customer network. Values can be snmpv2c or snmpv3, but snmpv3 is recommended due to security considerations.
C	snmpRo : Mandatory if col#=3 selected as  'snmpv2c'	If the legacy variant of SNMPv2 is selected for a specific device, then snmpRO (read only) credentials for the device SNMP collection must be specified. Otherwise, entry can be blank.
D	snmpv3UserName : Mandatory if col#=3 selected as 'snmpv3'	If SNMPv3 is selected to communicate with a specific device, then the respective login username must be provided.
E	snmpv3AuthAlgorithm : values can be MD5 or SHA	SNMPv3 protocol permits Authentication via either the MD5 or SHA Algorithm. If the device is configured with secure Authentication, then the respective Auth Algorithm must be provided.  Note: MD5 is considered insecure, and SHA can be used on all devices that support it.
F	snmpv3AuthPassword : password	If either a MD5 or a SHA cryptographic algorithm is configured on the device, then the relevant Authentication password needs to be provided for device access.
G	snmpv3PrivAlgorithm : values can be DES , 3DES	If the device is configured with the SNMPv3 privacy algorithm (this algorithm is used to encrypt the response), then the respective Algorithm needs to be provided. Note: 56-bit keys used by DES are considered too short to provide cryptographic security, and that 3DES can be used on all devices that support it.
H	snmpv3PrivPassword : password	If the SNMPv3 privacy algorithm is configured on the device, then its respective privacy password needs to be provided for device connection.
I	snmpv3EngineId : engineID, unique ID representing device, specify engine ID if manually configured on device	The SNMPv3 EngineID is a unique ID representing each device. This engine ID is sent as a reference while collecting the SNMP datasets by CX Cloud Agent. If the customer configures the EngineID manually, then the respective EngineID needs to be provided.
J	cliProtocol: values can be 'telnet', 'sshv1', 'sshv2'. If empty can set to 'sshv2' by default	The CLI is intended to interact with the device directly. CX Cloud Agent uses this protocol for CLI collection for a specific device. This CLI collection data is used for Assets and other Insights Reporting within CX Cloud. SSHv2 is recommended; absent other network security measures, in themselves SSHv1 and Telnet protocols do not provide adequate transport security.
K	cliPort : CLI protocol port number	If any CLI Protocol is selected, its respective port number needs to be provided. For example, 22 for SSH and 23 for telnet.
L	cliUser : CLI User name (either CLI username/password or BOTH can be provided, BUT both columns (col#=12 and col#=13) cannot be empty.)	The respective CLI username of the device needs to be provided. This is used by CX Cloud Agent at the time of connecting to the device during CLI collection.
M	cliPassword : CLI user password (either CLI username/password or BOTH can be provided, BUT both columns (col#=12 and col#=13) cannot be empty.)	The respective CLI password of the device needs to be provided. This is used by CX Cloud Agent at the time of connecting to the device during CLI collection.
N	cliEnableUser	If enable is configured on the device, then the device’s enableUsername value needs to be provided.
O	cliEnablePassword	If enable is configured on the device, then the device’s enablePassword value needs to be provided.
P	Future Support (No Inputs required)	Reserved for Future Use
Q	Future Support (No Inputs required)	Reserved for Future Use
R	Future Support (No Inputs required)	Reserved for Future Use
S	Future Support (No Inputs required)	Reserved for Future Use

Collection can be initiated on-demand or run according to a schedule defined here. Users can perform the first telemetry connection by selecting the Run the first collection now check box. Depending on the number of entries specified in the seed file and other factors, this process can take a considerable amount of time.

9. Click Connect. The Data Sources window opens, displaying a confirmation message.
   

Add Other Assets Using a Modified Seed File

To add, modify, or delete devices using the current seed file:

1. Open the previously created seed file, make required changes, and save the file. 
   

   Note: To add assets to the seed file, append those assets to the previously created seed file and reload the file. This is necessary since uploading a new seed file replaces the current seed file. Only the latest uploaded seed file is used for discovery and collection.

2. From the Data Sources page, click the CX Cloud Agent data source that requires an updated seed file. The CX Cloud Agent details window opens.
   CX Cloud Agent Details window
3. Click Replace Seed File. 
   CX Cloud Agent window
4. Drag-and-drop or click browse files to upload the modified seed file.
5. Click Upload.

Add Other Assets Using IP Ranges

IP ranges allow users to identify hardware assets and, subsequently, collect telemetry from those devices based on IP addresses. The devices for telemetry collection can be uniquely identified by specifying a single network-level IP range, which can be scanned by CX Cloud Agent using the SNMP protocol. If the IP range is chosen to identify a directly connected device, the IP addresses that are referenced can be as restrictive as possible, while allowing coverage for all required assets.

• Specific IPs can be provided, or wildcards can be used to replace octets of an IP to create a range.
• If a specific IP address is not included in the IP range identified during setup, CX Cloud Agent does not attempt to communicate with a device that has such an IP address, nor does it collect telemetry from such a device.
• Entering *.*.*.* allows CX Cloud Agent to use the user-supplied credential with any IP. For example: 172.16.*.* allows the credentials to be used for all devices in the 172.16.0.0/16 subnet.
• If there are any changes to the network or Installed Base (IB), the IP range can be modified. Refer to section Editing IP Ranges

CX Cloud Agent will attempt to connect to the devices but may not be able to process each one to show in the Assets view in cases where it is not able to determine the PIDs or Serial Numbers.

Notes:
Clicking Edit IP Address Range initiates on-demand device discovery. When any new device is added or deleted (within or outside) to a specified IP-range, customer must always click Edit IP Address Range (refer to section Editing IP Ranges) and complete the steps required for initiating the on-demand device discovery to include any newly added device to the CX Cloud Agent collection inventory.

Adding devices using an IP range requires users to specify all applicable credentials through the configuration UI. The fields visible vary depending on the protocols selected on the previous windows. If multiple selections are made for the same protocol, for example, selecting both SNMPv2c and SNMPv3 or selecting both SSHv2 and SSHv1, CX Cloud Agent automatically auto-negotiates the protocol selection based on the individual device capabilities.

When connecting devices using IP addresses, customer should ensure all relevant protocols in the IP range along with SSH versions and Telnet credentials are valid or the connections will fail.

About Devices Discovered from Multiple Controllers

It is possible that some devices could be discovered by both the Cisco DNA Center and direct device connection to CX Cloud Agent causing duplicate data to be collected from those devices. To avoid collecting duplicate data and having only one controller manage the devices, a precedence for which CX Cloud Agent manages the devices needs to be determined.

• If a device is first discovered by Cisco DNA Center and then rediscovered by direct device connection (using a seed file or an IP range), Cisco DNA Center takes precedence in controlling the device.
• If a device is first discovered by direct device connection to CX Cloud Agent and then rediscovered by Cisco DNA Center, Cisco DNA Center takes precedence in controlling the device.

Scheduling Diagnostics Scans

Customers can schedule on demand diagnostic scans in CX Cloud.

Note: Cisco recommends scheduling diagnostic scans or initiating on-demand scans at least 6-7 hours apart from inventory collection schedules so they do not overlap. Executing multiple diagnostic scans simultaneously can slow the scanning process and potentially result in scan failures.

To schedule diagnostic scans:

1. On the Home page, click the Settings (gear) icon.
2. On the Data Sources page, select Data Collection in the left pane.
3. Click Schedule Scan.

Configure Cisco DNA Center To Forward Syslog to CX Cloud Agent

Prerequisites

Supported Cisco DNA Center versions are 2.1.2.0 to 2.2.3.5, 2.3.3.4 to 2.3.3.6, 2.3.5.0, and Cisco DNA Center Virtual Appliance

Configure Syslog Forward Setting

To configure Syslog Forwarding to CX Cloud Agent in the Cisco DNA Center, perform these steps:

1. Launch Cisco DNA Center.
2. Go to Design > Network Settings >Network.
3. For each site, add the CX Cloud Agent IP as the Syslog Server.
   Syslog Server

Notes:
Once configured, all devices associated with that site are configured to send syslog with level critical to CX Cloud Agent. Devices must be associated to a site for enabling the syslog forwarding from the device to CX Cloud Agent. When a syslog server setting is updated, all devices associated with that site are automatically set to default critical level.

Configure Other Assets to Forward Syslog to CX Cloud Agent

Devices must be configured to send Syslog messages to the CX Cloud Agent to use the Fault Management feature of CX Cloud.

Note: Only Campus Success Track Level 2 devices are eligible to configure other assets to forward syslog.

Existing Syslog Servers with Forward Capability

Perform the configuration instructions for the syslog server software and add the CX Cloud Agent IP Address as a new destination.

Note: When forwarding syslogs, ensure that the source IP address of the original syslog message is preserved.

Existing Syslog Servers without Forward Capability OR without Syslog Server

Configure each device to send syslogs directly to the CX Cloud Agent IP Address. Refer to this documentation for specific configuration steps.

Security

CX Cloud Agent assures the customer of end-to-end security. The connection between CX Cloud and CX Cloud Agent is TLS secured. Cloud Agent’s default SSH user is limited to perform only basic operations.

Physical Security

Deploy CX Cloud Agent OVA image in a secured VMware server firm. The OVA is shared securely through Cisco software download center. Bootloader (single user mode) password is set with a randomly unique password. Users must refer to this FAQ to set this bootloader (single-user mode) password.

Account Security

During deployment, the cxcadmin user account is created. Users are forced to set a password during the initial configuration. cxcadmin user/credentials are used to access both the CX Cloud Agent APIs and to connect to the appliance over SSH.

cxcadmin users have restricted access with the least privileges. The cxcadmin password follows the security policy and is one-way hashed with an expiry period of 90 days. cxcadmin users can create a cxcroot user using the utility called remoteaccount. cxcroot users can gain root privileges.

Network Security

The CX Cloud Agent VM can be accessed using SSH with cxcadmin user credentials. Incoming ports are restricted to 22 (SSH), 514(Syslog).

Authentication

Password based authentication: Appliance maintains a single user (cxcadmin) which enables the user to authenticate and communicate with the CX Cloud Agent.

• Root privileged actions on the appliance using SSH.

cxcadmin users can create cxcroot user using a utility called remoteaccount. This utility displays an RSA/ECB/PKCS1v1_5 encrypted password which can be decrypted only from the SWIM portal (DECRYPT Request Form). Only authorized personnel have access to this portal. cxcroot users can gain root privileges using this decrypted password. Passphrase is valid only for two days. cxcadmin users must recreate the account and obtain the password from the SWIM portal post password expiry.

Hardening

CX Cloud Agent appliance follows Center of Internet Security hardening standards.

Data Security

CX Cloud Agent appliance does not store any customer personal information. Device credential application (running as one of the pods) stores encrypted server credentials inside secured database. The collected data is not stored in any form inside the appliance except temporarily when it is being processed. Telemetry data is uploaded to CX Cloud as soon as possible after the collection is complete and is promptly deleted from local storage after it is confirmed that the upload was successful.

Data Transmission

The registration package contains the required unique X.509 device certificate and keys to establish secure connection with Iot Core. Using that agent establishes a secure connection using Message Queuing Telemetry Transport (MQTT) over Transport Layer Security (TLS) v1.2

Logs and Monitoring

Logs do not contain any form of Personal Identifiable Information (PII) data. Audit logs capture all security-sensitive actions performed on the CX Cloud Agent appliance.

Cisco Telemetry Commands

CX Cloud retrieves asset telemetry using the APIs and commands listed in the Cisco Telemetry Commands. This document categorizes commands based on their applicability to the Cisco DNA Center inventory, Diagnostic Bridge, Intersight, Compliance Insights, Faults, and all other sources of telemetry collected by the CX Cloud Agent.

Sensitive information within asset telemetry is masked before being transmitted to the cloud. The CX Cloud Agent masks sensitive data for all the collected assets that send telemetry directly to the CX Cloud Agent. This includes passwords, keys, community strings, usernames, and so on. Controllers provide data masking for all controller-managed assets before transferring this information to the CX Cloud Agent. In some instances, controller-managed assets telemetry can be anonymized further. Refer to the corresponding product support documentation to learn more about anonymizing the telemetry (for example, the Anonymize Data section of the Cisco DNA Center Administrator Guide).

While the list of telemetry commands cannot be customized and the data masking rules cannot be modified, customers can control which assets’ telemetry CX Cloud accesses by specifying data sources as discussed in the product support documentation for controller-managed devices or the Connecting Data Sources section of this document (for Other assets collected by CX Cloud Agent).
