Cisco Crosswork Data Gateway 1.1.4 Release Notes

This document describes the features, limitations, and bugs for Cisco Crosswork Data Gateway 1.1.4.

This document includes the following sections:

Introduction

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 is not a standalone product and needs to be deployed in either a Cloud or On Premise configuration. See Compatibility Information.

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

New Features, Enhancements, and Requirements

New features and enhancements provided in the Cisco Crosswork Data Gateway 1.1.4 release include:

  • Changes in VM Requirements:

    • Disk space requirement increased from 50 GB to 70 GB.

Release Dates

Cisco releases updated builds on the Cisco Support & Download site when needed.

Compatibility Information

  • Cisco Crosswork Data Gateway 1.1.4 has been qualified to be used only with Crosswork Cloud applications.

  • Cisco Crosswork Data Gateway release 1.1.4 has been validated in conjunction with the following Crosswork applications:

    • Cisco Crosswork Trust Insights

You can deploy Cisco Crosswork Data Gateway as a VM on a host that meets the following minimum requirements:

Table 2. Cisco Crosswork Data Gateway VM requirements

Requirement

Description

Hypervisor

  • VMware vCenter Server 6.7 Update 3g or later (ESXi 6.7 Update 1 installed on hosts)

  • VMware vCenter Server 6.5 Update 2d or later (ESXi 6.5 Update 2 installed on hosts)

Memory

32 GB

Disk space

50 GB

vCPU

8 vCPUs

Interfaces

Minimum: 1

Maximum: 3

Cisco Crosswork Data Gateway 1.1.3 can be deployed with either 1, 2, or 3 interfaces as per the combinations below:

Combination #

vNIC0

vNIC1

vNIC2
1

  • Management Traffic

  • Device Access Traffic

  • Control/Data Traffic

—

—
2

  • Management Traffic

  • Device Access Traffic

  • Control/Data Traffic

—
3

  • Management Traffic

  • Device Access Traffic

  • Control/Data Traffic

  • Management traffic: for accessing the UIs and command line and passing Control/Data information between servers (for example, Cisco Crosswork Change Automation and Health Insights to Cisco Crosswork Data Gateway or NSO).

  • Device access traffic: for device configuration and management (NSO or to the devices as a result of KPI configuration or playbook execution) and telemetry data being forwarded to the Cisco Crosswork Data Gateway.

  • Control/Data traffic: for data and configuration transfer between Cisco Crosswork Data Gateway and and other data destinations.

IP Addresses

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

Note 

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.

Also, the ESXi hosts that will run the and Cisco Crosswork Data Gateway VM must have NTP configured, or the initial handshake may fail with "certificate not valid" errors.

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.

Destination Networks

For live deployments, we recommend one virtual switch for the Data Network (connection between the VM and the Cisco Crosswork Data Gateway VM) and second virtual switch for all the management traffic (vms to dns, ntp and the network you will use to access and manage the applications).

Table 3. VM Requirements

Interfaces

There are three interfaces available. However, only two interfaces (i.e., vNIC0 and vNIC1) are applicable for cloud deployment.

Cisco Crosswork Data Gateway 1.1.4 can be deployed with either 1 or 2 interfaces as per the combinations below:

Combination #

  • Management Traffic

  • Control/Data Traffic

  • Management traffic: for accessing the UIs and command line and passing Control/Data information between servers (for example, Crosswork application to Cisco Crosswork Data Gateway or NSO).

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

IP Addresses

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

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.

Features and Enhancements in Cisco Crosswork Data Gateway 1.1.4

This section lists the features/functionalities delivered in Cisco Crosswork Data Gateway 1.1.4:

Feature

Description

Accessing SCP server via a custom port

Cisco Crosswork Data Gateway allows you to use a custom port instead of the default SCP Port 22.

You can specify the port as a part of the SCP command. For example,

-P55 user@host:path/to/file

where 55 is a custom port.

Cisco Crosswork Data Gateway provides report of its available bandwidth and performance. This includes Network I/O, Disk I/O, Memory, and CPU utilization.

Centralized logging

Lets you use an external syslog server.

Deploy Cisco Crosswork Data Gateway with either 1 or 2 NICs configurations

You can choose to use either 1 or 2 vNICs as per the following combinations:

  1. Send all traffic through vNIC0.

  2. Send management traffic through vNIC0 and all data traffic through vNIC1.

Test SSH Connection

Cisco Crosswork Data Gateway allows you to test the SSH connection between itself and a remote host.
