You can also achieve the same effect with subnet and VLAN design. The default Beacon Timeout is based on a nominal device, embedded switch ring with m cables between devices. The primary yd001 secondary supervisors are determined by the Supervisor Precedence. Table of Contents Preface Switch Topology. Inserting device-level topologies between the managed switches may lead to unexpected results. You can contact Customer Support for initial help in getting your product up and running.

The device-level topology limits the scope of the issue to communication through the switch and peer-to-peer devices. If you must mix MSTP protocol with embedded switch topology, we recommend using either a device-level or physical chassis segmentation topology.

This beacon adds up to 2, pps of traffic that is only needed in a ring topology. Allen-Bradley devices with embedded switch technology have gd001 features in common: The test alternates failing and then restoring the root port on IES There are three break points in the ring: Embedded switch technology adds the choices of device-level topologies: In these cases, a bridge loop is created and causes a network failure.

United States or Canada 1. Supervisor The DLR ring supervisor maintains a loop-free topology by blocking port 2 of the embedded-switch device. This test verifies the detection of a failed supervisor. A failure introduced at IES-7 forces a topology change.

There are two break points in the redundant star topology: However, immediately after link-up rnet interface will send a few BPDUs to ensure a loop free topology. The chassis segmentation topology keeps the embedded switch topology completely isolated from the MSTP network. Industrial Automation Wiring and Grounding Guidelines, publication Mixed Embedded Switch and Single-port Technology.

This test verifies connectivity from outside the DLR topology to inside at a topology change. The same set of tests were executed against the root port on IES This allows for a ring fault recovery time of less than 3ms.

Rockwell Otomasyon Ticaret A.

Linear topologies can be connected directly to the switch. If the ring closed before the supervisor is enabled, a bridge loop results, which generates a broadcast storm.

If t0d01 back-up supervisor does not hear the supervisor for a period of time, it assumes the supervisor failed and takes over the supervisor role. New Product Satisfaction Return Rockwell Automation tests all of its products to ensure that they are fully operational when shipped enst the manufacturing facility. Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc. We do not recommend connecting device-level topologies directly to Layer 3 distribution switches.


This pattern of switches alternately connecting and failing will continue indefinitely. In no event will Rockwell Automation, Inc. This topology also lets you connect multiple, device-level topologies to the same IES switch. We do not recommend using device-level topologies as the backbone of the network. However, if your product is not functioning and needs to be returned, follow these procedures. Use the embedded switch technology in the following situations: Test Description Switch ring This test measures timeouts in the DLR topology due to 10 software shutdowns and 10 physical disconnections in the switch ring.
