Hi folks,I'm wondering if NetFlow is supported with the collector behin the oob management nowadays. For the flow exporter you can select EPG or External EPG but you can also leave both blank which gave me some hope that if you select out-of-band IP ...

Hi folks,we've setup inband management on our ACI lab enironment. All switches and APIC can ping each other just fine. Then we have an L3Out in the management Tenant to allow external devices to reach the fabric nodes via their inband management addr...

Hi folks, first of all: We have already opened a TAC case, but I thought it cannot hurt to have several irons in the fire This is our situation: We have a Multi-Pod environment with 100 Gbps links from the Spines to the IPN and a full mesh of 400 Gb...

Hello community,I apologize, it will be a rather long text, but I think I have to explain a lot and will still be missing half of the important information :SWe have a single-pod ACI fabric: The leaf switches on the lower end of the diagram connect ...

Dear community, we have an ACI Multi-Pod environment with two Pods and one ESXi host connected to each of them. A static vPC is configured from the host to two leaf switches to provide failover redundancy: So far so good. If a leaf switch fails or a...

Hi @RedNectar,thanks for your reply  You're absolutely right, I failed to provide all context.So, everything is in VRF inb ans yes, there are other solutions than using a contract but all lead to the same result. Setting the VRF to unenforced is bas...

I'm happy to announce that we successfully upgraded our Spine to IPN bandwidth.We followed Balaji's suggestion to modify the ospf link cost on all interfaces. To be more precise we set the exact same ospf cost value for all links no matter the bandwi...

Thank you for your input Julian,this could indeed lead to the behavior that we have and it's a totally new angle to look at the issue. Highly appreciated!However, I doubt that we have a problem processing IGMP joins. After all you can see that the co...
