Introduction
Visibility into application traffic is important for infrastructure operations to maintain security and compliance, and to perform resource planning and troubleshooting. With the technological advances and growth in cloud-based applications, it has become imperative to gain increased visibility into the network traffic. Traditional approaches to gain visibility into network traffic are expensive and rigid, making it difficult for managers of large-scale deployments.
Cisco Nexus Dashboard Data Broker with Cisco Nexus Switches provides a software-defined, programmable solution to aggregate copies of network traffic using SPAN or network taps for monitoring and visibility. As opposed to traditional network taps and monitoring solutions, this packet-brokering approach offers a simple, scalable and cost-effective solution well-suited for customers who need to monitor higher-volume and business-critical traffic for efficient use of security, compliance, and application performance monitoring tools.
Cisco Nexus Dashboard Data Broker also provides a software-defined, programmable solution to perform inline inspection of the network traffic for monitoring and visibility purpose. Inline traffic inspection is performed on specific traffic by redirecting it through multiple security tools before it enters or exits a network.

General
● A Cisco Nexus Dashboard Data Broker instance can support only the NX-API configuration mode.
● By default, the Nexus Dashboard Data Broker cluster URL is https://<IP_address>:8443
● The switchport mode trunk and spanning-tree bpdufilter enable command should be enabled for all switch ports on all Cisco Nexus Dashboard Data Broker managed switches.
● Cisco Nexus switches managed by Cisco Nexus Dashboard Data Broker in NX-API mode must have LLDP feature enabled. Disabling LLDP may cause inconsistencies and require switch rediscovery for NX-API switches.
● For secured communication between Cisco Nexus Dashboard Data Broker and switch through HTTPS, start the Cisco Nexus Dashboard Data Broker in TLS mode for the first time only. Subsequent restarts does not require TLS mode.
For more details, see Cisco Nexus Dashboard Data Broker Configuration Guide.
● The TLS KeyStore and TrustStore passwords are sent to the Cisco Nexus Dashboard Data Broker so it can read the password-protected TLS KeyStore and TrustStore files only through HTTPS
./ndb config-keystore-passwords [--user {user} --password {password} --url {url} –verbose --prompt --keystore-password {key-store_password} --truststore-password {truststore_password}
● Cisco Nexus 92xx devices do not support QnQ; you cannot use this switch in a multi-switch environment.
● Dry Run feature is disabled by default. To enable this feature, see the Configuration Guide.
● Do not configure TACACS on the Cisco NDB devices. You can configure it only for authentication and authorization. It is not to be used for accounting.
