In my first weblog in this series on objective constructed switches, I detailed the sturdy {hardware} design of our Industrial Ethernet switches that allows them to face up to harsh environments. On this weblog, I’ll give attention to their software program options – notably the help of commercial communications protocols – additional cementing the “objective” in these purpose-built merchandise.
Cisco’s IE (Industrial Ethernet) switches are designed to leverage as a lot of Cisco’s know-how as attainable. This contains {hardware} and software program options. Clients anticipate our software program options to behave persistently throughout product households, together with the IE Switching merchandise. Cisco IE switches additionally run IOS or IOS-XE. There are variations. One distinction between Enterprise and Industrial Switching is help for industrial protocols.
What’s a protocol? Protocols outline the algorithm by which gadgets talk with one another. The web runs on a protocol referred to an IP. Industrial communications have been utilizing protocols since earlier than IP turned as common as it’s at this time. Each trade appears to have its personal set of protocols. Cisco IE switches help a overwhelming majority of those protocols enabling them to be a part of any industrial networking resolution.
Protocol help is one among many causes that makes Cisco IE Switching common
Our Industrial Ethernet (IE) switches are the global market leader in Industrial Ethernet Switching for a number of causes:
- Supply a portfolio of din rail and rack mount of industrialized switching merchandise to suit a number of use instances
- Have a top quality, built-to-purpose ruggedized {hardware} design for reliability in industrial deployments
- Leverage Cisco’s community administration and safety applied sciences
- Assist of protocols that allows industrial prospects to simply incorporate Cisco’s networking merchandise into their deployments and options.
Why help industrial protocols?
Briefly, as a result of these protocols are very important for the performance of any fashionable industrial operation.
Cisco builds community gadgets to be deployed in all kinds of commercial networks and options. No two industrial networks are alike. There’s all kinds of necessities and use instances. And there may be a minimum of one protocol utilized in each industrial resolution. The networking infrastructure should help all necessities, use instances, and protocols, it doesn’t matter what they’re.
We prefer to assume we don’t have a know-how bias. Whereas specializing in our key competency, networking, we’ll construct what prospects wish to deploy. This is applicable as nicely to help of commercial protocols. We’re not selling or supporting one industrial protocol over one other. We’re not sure to anyone know-how, resolution set, or protocol.
Finish customers, system integrators, and anybody placing collectively an answer wish to use the instruments and purposes they know and belief and on the identical time reap the benefits of the state-of-the-art networking know-how. To allow the instruments and purposes utilized in industrial deployments, our IE switches help industrial protocols used to construct options primarily based on Ethernet networks. Failure to help an industrial protocol usually eliminates a networking product as a viable possibility.
What does help for industrial protocol imply?
Identical to the numerous industries and protocols, help anyone protocol means various things. Protocols differ broadly, thus help does too. In case you will need to have a single definition of help, help for an industrial protocol will be equated to ‘talking the language’. Our IE switches help the communication of commercial protocols enabling finish gadgets to speak successfully and effectively.
Determine 1: communication move by means of the Cisco IE change
PROFINET and Ethernet/IP CIP are two protocols generally utilized by industrial automation and management techniques (IACS). Our IE switches are licensed compliant to those two protocols by together with the software program stacks for them. It’s the identical software program stack because the IACS parts. For PROFINET and Ethernet/IP, the Cisco IE switches actually do converse the language. Functions utilizing PROFINET or Ethernet/IP can uncover and mechanically setup Cisco IE switches as part of the answer, thus avoiding guide procedures.
For different protocols, help could imply recognition. GOOSE is an efficient instance of such a protocol. Our IE switches don’t must help the GOOSE software program stack. Protocols corresponding to GOOSE use Layer2 Ethernet or Layer3 Web protocol. Customers can construct high quality of service insurance policies to prioritize the communication of those protocols. The Cisco IE change can acknowledge and prioritize industrial protocol working on customary Ethernet or Web protocol primarily based messages within the community guaranteeing finish to finish high quality of service. Whatever the interplay and help for industrial protocols, Cisco IE switches present quick, dependable, and secured transport.
What about security protocols?
Particularly security protocols. Equivalent to PROFIsafe, and CIP Security.
Assist for any protocol implies help for the security portion of the protocol. Industrial automation (eg: manufacturing) options prioritize help for security protocols. If a protocol has a security element, then our IE switches help the security protocol. More often than not this implies recognizing the protocol or the security messages within the protocol and constructing a quality-of-service coverage to prioritize the communication finish to finish.
What about Cyber Imaginative and prescient?
Cisco Cyber Imaginative and prescient is an software that runs on Cisco IE switches and makes use of deep packet inspection to research all site visitors passing by means of the change and establish industrial protocols in use.
Cyber Imaginative and prescient does greater than ‘converse the language’. Utilizing its information of commercial protocols, Cyber Imaginative and prescient can establish industrial property and decide if the payload in these protocols is inside working bounds. It additionally offers safety posture assessments of IACS parts.
The appliance working on our IE switches report a summarized model of its findings to the Cyber Imaginative and prescient heart, the place finish customers get a real-time visible illustration of all of the communications on their operational community.
The determine beneath is an instance of how Cyber Imaginative and prescient allows customers to visualise communication between gadgets. It acknowledges which system is talking which protocol amongst different issues.
Determine 2: Cybervision visualizes system communication flows
Cyber Imaginative and prescient is a safety instrument to extend visibility into operational networks. You’ll be able to’t safe what you’ll be able to’t see. To be taught extra, go to the Cyber Vision page on Cisco.com.
Closing
Finally, it’s about providing you with, the client, what you need and what you want. You need the most recent and best know-how since you’re investing for the long run. You need high quality, which is why you’ve chosen IE switches from Cisco. You need ease of use. You wish to construct techniques and options with the instruments , belief and which you have already got invested in.
Failure to supply any of the above means the client should compromise. No one desires that. With Cisco IE Switching, you don’t must.

Temporary Description of choose industrial protocols (with examples)
In case you’re new to industrial networking, you could find a quick overview of the principle industrial protocols beneath.
Why so many protocols? Totally different industries have completely different protocols they’ve developed through the years to fulfill their wants. Most industrial protocols leverage the Web protocol (IP) for communication. However not at all times.
