This document provides information about Cisco Crosswork Data Gateway 6.0.1 for Cloud applications, including features, compatibility information, known issues, and limitations.
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.
Cisco Crosswork Data Gateway is not a standalone product and is expected to be used with Crosswork Cloud applications. There is no separate software license needed for Cisco Crosswork Data Gateway.
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 any of the platforms listed in the following table. The file used for deployment is unique to each of these environments.

Direct upgrade from a previous Crosswork Data Gateway version is not supported. You must create a new VM with the same parameters to replace the existing Crosswork Data Gateway. |
What's New
This section lists the features and enhancements delivered in Crosswork Data Gateway 6.0.1 for Cloud Applications.
|
Feature |
Description |
|---|---|
| Auto enroll Crosswork Data Gateway with Crosswork Cloud1 |
Crosswork Cloud enrolls Cisco Crosswork Data Gateway, permitting it the ability to receive collection job configurations and gather data from network devices. Previously, enrolling a data gateway with Crosswork Cloud was possible only after the installation of the data gateway on the VM. To enroll the data gateway, you would generate an enrollment package from Crosswork Data Gateway and upload it using the Crosswork Cloud UI. In the 6.0.1 release, you would generate an enrollment token from the Crosswork Cloud UI and incorporate it into the configuration file during the deployment of the data gateway VM. Through this approach, the data gateway seamlessly enrolls with the Crosswork Cloud upon VM startup. You can choose to enroll the data gateways manually or automatically using this feature. For information on the enrollment procedures, see Enroll Crosswork Data Gateway with Crosswork Cloud. |
| Ability to configure multiple Syslog servers1 |
In the Day 0 configuration, you can configure one or more remote servers to use the same port and protocol. After the Day 1 configuration, you can modify the remote server settings using the interactive menu. You can customize the server IP, port, protocol, TLS peer name, and Syslog root certificate with this option. When one of the servers becomes inaccessible, a standby server takes its place to ensure continuity. The objective of having numerous servers is to achieve high availability. |
| Option to modify the interface address1 |
Crosswork Data Gateway allows you to modify the interfaces that are already associated with a data gateway instance after it has been installed. When Crosswork Data Gateway indicates IP address difficulties such as address conflicts or erroneous addresses, this may be required. Reconfiguring an interface involves modifying the interface name, assigning it an IP address, and obtaining access to the security group that is linked to it. |
|
Included the auto-configuration functionality to deploy Crosswork Data Gateway |
To use the auto-configuration feature, the user defines only the essential parameters with default values in the Day 0 configuration. Auto-configuration feature discovers the missing configuration parameters and configures the required parameters to install Base VM. The Dynamic Host Configuration Protocol (DHCP) framework is used to communicate the configuration settings. For more information about the auto-configuration feature, see the Auto-configuration for Deploying Crosswork Data Gateway section in Cisco Crosswork Data Gateway 6.0.1 Installation and Configuration Guide for Cloud Applications. |
|
Support to assign roles to the vNICs |
Role assignment allows you to control the traffic that an interface must handle. By default, all form of communication occurs through the network using eth0. During the installation, you can assign roles to different interfaces to match the unique requirements of your environment. Each parameter has a predefined role. The parameter accepts the interface value as eth0, eth1, or eth2. The fourth interface, eth3, allows you to separate SSH, Management, Control (Crosswork Cloud service), and Northbound External Data, and Southbound Data traffic. For more information about the different roles, see Cisco Crosswork Data Gateway Deployment Parameters and Scenarios. |

IP Addresses |
One, two, or three IPv4 or IPv6 addresses based on the number of interfaces you choose to use.
|
|||||
|
NTP Servers |
The IPv4 or 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.
The Crosswork Data Gateway host and virtual machine must be synchronized to an NTP server or the enrollment with Crosswork Cloud may not go through. |
|||||
|
DNS Servers |
The IPv4 or IPv6 addresses of the DNS servers you plan to use. If you want to enter multiple DNS servers, separate them with spaces. 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. |
|||||
| (Optional) Proxy Server |
URL of an optional management network proxy server. If your environment requires an HTTP or HTTPS proxy in order to access URLs on the public Internet, you must configure a proxy server for the Cisco Crosswork Data Gateway to successfully connect to the Crosswork Cloud service. |
|||||
