Installation Requirements

You can deploy Crosswork Data Gateway either on VMware or on Cisco Cloud Services Platform (Cisco CSP) hosts. This section provides information about the general guidelines and minimum requirements for installing Crosswork Data Gateway on either platform.

This section contains the following topics:

VM Requirements

The requirements are same for both VMware and Cisco CSP, unless stated otherwise.

Table 1. Cisco Crosswork Data Gateway VM Requirements

Requirement

Description

Data Center

VMware

  • VMWare vCenter 7.0, ESXi 7.0 installed on the hosts

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

Cisco CSP

  • Cisco CSP 2.8.0.276 or later

    Allowed_hardware_list = ['CSP-2100', 'CSP-2100-UCSD', 'CSP-2100-X1', 'CSP-2100-X2','CSP-5200', 'CSP-5216', 'CSP-5228','CSP-5400', 'CSP-5436', 'CSP-5444', 'CSP-5456']

  • Management Traffic

  • Control/Data Traffic

  • Device Access Traffic

  • Management traffic: for accessing the Interactive Console and troubleshooting the Crosswork Data Gateway VM.

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

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

IP Addresses

One, two or three 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.

The Cisco 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/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.

Note
The Cisco Crosswork Data Gateway application is bundled with Ubuntu Server 20.04.2. Cisco will provide updates as need to address security and other fixes.

In Cloud deployments, Cisco Crosswork Data Gateway must connect to the Internet via TLS, and a proxy server may be required. If there is a proxy server in the network, it needs to be configured either during the installation process or from the Interactive Console of the Crosswork Data Gateway VM after installation. See:

Ports Used

The following table shows the minimum set of ports needed for Cisco Crosswork Data Gateway to operate correctly.


Note

This is only to enable the base Cisco Crosswork Data Gateway functionality. Additional ports may be used depending on the application that is running in the Cisco Crosswork Data Gateway.


Note

The SCP port can be configured.
