In this article we will be implementing Layer 2 NAT with Layer 3 routing as shown in the the network topology depicted below. For this example we will be leveraging two Allen-Bradley Stratix 5700 Managed Industrial Ethernet switches (Full Software Version) and three Logix based controllers (machines). With Stratix 5700 NAT capability configured, we can setup a NAT instance per VLAN. When we create multiple VLANs on one Stratix 5700 switch we can connect multiple identical machines and leverage Layer 3 routing to route between the various VLANs.
Stratix 5700 Smartports are the recommended configurations for switch ports. These configurations, referred to as smartport roles, optimize the switch connections and provide security, transmission quality, and reliability for traffic to-from the switch ports. The smartport roles also help prevent port misconfigurations.
Stratix 5700 Inter-VLAN Routing can be defined as a way to forward traffic between different VLANs by implementing a router in the network. VLANs logically segment the switch into different subnets, and the routing capabilities of the Stratix 5700 can be configured to route or forward the traffic between the various VLANs configured.
In this video I will show you step-by-step how configure the your new Stratix 5700 using the Stratix 5700 Express Setup Mode.
While the Express Setup itself is meant to be an easy method by which to configure the Stratix 5700 managed switch, it can be a little daunting initially. As a result, you can waste a considerable amount of time just trying to get passed the initial setup.
Hopefully, this video will alleviate that “pain” and get you up and running and into the switch as quickly as possible. I do recommend, if you haven’t done so already, you check out our introductory video on how to Configure PC to PLC Communication as part of our Networking Essentials video series.
