This document provides information about Cisco Crosswork Data Gateway 3.0.2, including features, compatibility information and updates.

Product Overview

Cisco Crosswork Data Gateway is a model-driven scalable data collection platform that enables real-time data collection from multi-protocol capable devices, thereby reducing the need for multiple collection points for multiple applications requiring data from the network.

Cisco Crosswork Data Gateway offers central visibility into services collecting data and the type of data being collected. It can also be used to feed external data destinations (such as, an external Kafka or gRPC server) in addition to Crosswork applications.

Cisco Crosswork Data Gateway is not a standalone product and is expected to be used with Crosswork on-premise or Crosswork Cloud applications. There is no separate software license needed for Cisco Crosswork Data Gateway. Use of Cisco Crosswork Data Gateway to forward data to third-party destinations is only supported when using the Crosswork Data Gateway with Crosswork on-premise applications and requires a separate license.

Release Details

Cisco releases updated builds of Crosswork Data Gateway on the Cisco Support & Software Download site.

Cisco Crosswork Data Gateway can be installed into a data center using either the Cisco Cloud Services Platform (CSP) or VMware. The file used for deployment is unique to each of these environments. Use:

  • *.ova file - to install Crosswork Data Gateway on VMware.

  • *.qcow2 file - to deploy Crosswork Data Gateway on Cisco Cloud Services Platform (CSP).

Interfaces

Minimum: 1

Maximum: 3

Crosswork Data Gateway can be deployed with either 1, 2, or 3 interfaces as per the combinations below:

No. of NICs

vNIC0

vNIC1

vNIC2

1
  • Management Traffic

  • Control/Data Traffic

  • Device Access Traffic

2*
  • Management Traffic

  • Control/Data Traffic

  • Device Access Traffic

3*
  • Management Traffic

  • Control/Data Traffic

  • Device Access Traffic

  • Management traffic: for accessing the UIs and command line and passing configuration information between servers (for example, a Crosswork application to Crosswork Data Gateway)

  • Control/Data traffic: for data and configuration transfer between Crosswork Data Gateway and Crosswork applications.

  • Device access traffic: for device management and telemetry data.

(*) - For live deployments, we recommend 3 NIC deployment, that is one interface for all management traffic (VMs to DNS, NTP, and the network you will use to access and manage the applications), second interface for the data network (connection between Cisco Crosswork and the Cisco Crosswork Data Gateway VM) and and third interface to communicate with devices in the network.

IP Addresses

1, 2, or 3 IPv4/IPv6 addresses based on the number of interfaces you choose to use.

Note 
Cisco Crosswork does not support dual stack configurations. Therefore, ALL addresses for the environment must be either IPv4 or IPv6.

NTP Servers

The IPv4/IPv6 addresses or host names of the NTP servers you plan to use. If you want to enter multiple NTP servers, separate them with spaces. These should be the same NTP servers you use to synchronize devices, clients, and servers across your network. Confirm that the NTP IP address or host name is reachable on the network or installation will fail.

The Crosswork Cloud application and Cisco Crosswork Data Gateway VM must must be synchronized to an NTP server, or enrollement with Crosswork Cloud may not go through.

DNS Servers

The IPv4/IPv6 addresses of the DNS servers you plan to use. These should be the same DNS servers you use to resolve host names across your network.

DNS Search Domain

The search domain you want to use with the DNS servers (for example, cisco.com). You can only have one search domain.
