Good afternoon! Below is the network diagram detailing the configuration of the supervisor on the en2tr module. The Stratix is currently operating in RSTP mode, causing it to block one of the Gi1/2 ports on a line with Multiport Automation Device roles. When I activate the first supervisor on the en2tr module, I can only access backplane addresses within the same cabinet, not those in other locations connected via fiber optic lines. Despite both PLC and RSLinx connections being established, I am unable to view backplanes from other cabinets. Time synchronization is temporarily disabled, and the speed is consistently set to 100 across all devices. What could be causing this issue? Any insights would be greatly appreciated. Thanks!
It is important to note that Spanning Tree and DLR cannot be combined on the same network ring. All ports on a Stratix switch involved in DLR must be correctly configured for DLR and Smartport to work effectively with a Multiport Automation device, using access port single VLAN. Additionally, it is advisable to use Fiber for switch-to-switch connections, requiring SFPs that support 100Mb speeds.
Contr_Conn mentioned the importance of not mixing Spanning Tree Protocol (STP) and Device Level Ring (DLR) on the same network ring. All ports on Stratix involved in DLR must be properly configured as DLR and Smartports set for a Multiport Automation device, with access port single VLAN settings. Additionally, it is assumed that the switch to switch connections are via Fiber, requiring 100Mb SFPs. After implementing these configurations, a successful setup was achieved, although there was a discrepancy in identifying the network as DLR. Furthermore, an issue was encountered where the Cisco device became disconnected from the Stratix switch.
If your Cisco is disconnected despite appearing as a regular ring, there may be a separate underlying issue. This could be due to multiple pathways leading to a distribution point that necessitates a redundant gateway.
In response to Contr_Conn, it appears that your ring is displaying as a typical ring structure, which could be why your Cisco device is disconnected. This issue may stem from a separate underlying problem, such as multiple pathways to a distribution point necessitating a redundant gateway. Thank you for the clarification and insight provided.
Hi there! If I understand correctly, you're having trouble getting access to backplane addresses beyond your local cabinet, right? My first inclination is the problem could be attributed to the network structure. In particular, when incorporating fiber optics into a LAN setup like this, it's crucial that both the signal strength and signal fidelity are properly maintained for successful communication between cabinets. You may want to give your fiber optic lines a thorough inspection to ensure no physical damage or deterioration that could be affecting signal quality. If those are fine, look into your RSTP settings. Try tweaking those and see if it improves the reach beyond your local cabinet. Hope that offers you a start!
Hello! Based on the issue you've described, it appears this could be a problem with the configurations on your fiber optic lines. While the en2tr module is engaged and your Stratix operating in RSTP mode should help avoid loops, the issue may be connected to VLAN or routing strategies. It might be beneficial to double-check your VLAN settings and also ensure that the routing information is correctly propagated on fiber optic lines. Additionally, ensure that your patch cables are in good working condition. Just by focusing on these areas, you might be able to solve the problem with accessing backplanes from other cabinets. Good luck!
It sounds like you're dealing with a tricky networking issue! Since you're in RSTP mode and facing connectivity problems with backplane addresses across different cabinets, it's possible that the spanning tree protocol is not allowing the proper routing of traffic due to the blocked port. Have you checked the configuration settings on the switches for proper VLAN tagging or any misconfigurations that could be limiting the communication? Additionally, since time synchronization is off, it might be worth looking into how that could impact your connections, especially if you’re using protocols that require timestamp accuracy. It may help to troubleshoot those connections step-by-step to isolate where the breakdown occurs. Good luck!

Answer: - The Stratix 5700 may be blocking one of the Gi1/2 ports due to a configuration issue or a network loop. Check the RSTP configuration settings and ensure there are no loops in the network.
Answer: - The limitation to access backplane addresses in other locations connected via fiber optic lines could be due to network routing or VLAN configuration issues. Verify the network routing setup and VLAN configurations to ensure proper communication across locations.
Answer: - The inability to view backplanes from other cabinets despite established connections could indicate a network segmentation issue or firewall restrictions. Check the network segmentation settings and firewall rules to enable communication between cabinets.
Answer: - Disabling time synchronization and maintaining consistent speed settings across devices should not directly impact the ability to view backplanes from other locations. Consider checking for IP address conflicts, subnetting issues, or routing problems that may be affecting cross-cabinet communication.
