Switch redundant star This test measures timeouts in ehet DLR topology due to 10 software shutdowns and 10 physical disconnections in the redundant star topology. If you have any suggestions on how to improve this document, complete this form, publication RA-DU, available at http: Labels may be on or inside the equipment, for example, a drive or motor, to alert people that dangerous voltage may be present.

In these cases, a bridge loop is created and causes a network failure.

The tests use a traffic generator ixia traffic simulator to measure network recovery performance for both ttd001 and multicast traffic. The test alternates failing and restoring the active port on IES Installation Assistance If you experience a problem within the first 24 hours of installation, review the information that is contained in this manual.

A new role, which was added in IOS version Industrial Automation Wiring and Grounding Guidelines, publication We do not recommend using device-level topologies as the backbone of the network.

In addition to the existing service policy, the interface now trusts the DSCP value. You can contact Customer Support for initial help in getting your product up and running. Documentation Feedback Your comments will help us serve your documentation needs better. It lets you combine both single-port devices and devices with embedded switch technology.

This test assesses DLR outages when the redundant switch topology experiences a disruption. This is essential to allow for linear or ring topologies of embedded switch devices.

With embedded switch technology, IACS end-devices can be directly connected to each other without the need for additional IES switches. A block on either of these ports is acceptable.


There are three break points in the ring: Both linear and DLR topologies can be ehet to a switch topology. It is possible under rare circumstances or misconfiguration that the supervisor will fail but traffic will continue to flow. Labels may be on or inside the equipment, for example, a drive or motor, to alert people that surfaces may reach dangerous temperatures.

Throughout this manual, when necessary, we use notes to make you aware of safety considerations. Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. The worst case failure is that the loop will be undetectable and will generate a broadcast storm that will take down the network.

Product Certifications website, http: Considerations for Resiliency Protocols. This topology can also provide a false sense of security in that it does not filter CIP traffic between the IES switch topology and the device-level topology. Eney allows for a ring fault recovery time of less than 3ms. This eh verifies that a disruption to the switch ring has no impact on the DLR topology. Because of this difference, and also because of the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

This beacon adds up to 2, pps of traffic that is only needed in a ring topology. New Product Satisfaction Return Rockwell Automation tests all of its products to ensure that they are fully operational when shipped from the manufacturing facility.

Flex Links Redundant star Use the mixed topology when connecting to a network using Flex Links protocol. The same set of tests were executed against the root port on IES These BPDUs will cause any other switches connected to the embedded switch network to fail into the err-disable state. If the back-up supervisor does not hear the supervisor for a period of time, it assumes the supervisor failed and takes over the supervisor role.

ennet In these tests, the ring is connected to additional switches. There are two key changes in the ab-multiport-device macro. Guidelines for Connecting Device-level and Switch Topologies.

Because these ports are connected to a single NIC, they cannot be used to connect to multiple Ethernet networks. This pattern of switches alternately connecting and failing will continue indefinitely. Attentions help you identify a hazard, avoid a hazard, and recognize the consequence. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. No additional switches are required.

In the case of DLR, the supervisor with the highest precedence value will become the active supervisor on the network. The disadvantage of this topology is that it may require direct connection to the device-level topology for dn operations yd001 non-CIP devices, such as diagnostics and configuration.

Outside United States Please contact your local Rockwell Automation representative for the return procedure. The backup supervisor must detect that the supervisor is no longer present and block port 2.

To avoid this, configure a secondary supervisor in the ring.
