Fabric discovery is an important process in Cisco Data Center infrastructure, as it allows switches and nodes to discover and join the fabric network. When fabric discovery fails, the network switches and nodes cannot join the fabric, and connectivity is lost. To troubleshoot fabric discovery failure, two requirements about switch connectivity that must be verified are:
B. A Cisco APIC must be attached to leaf nodes: The Cisco Application Policy Infrastructure Controller (APIC) is the centralized management and configuration point for the Cisco Data Center network fabric. It is responsible for managing the network switches, nodes, and policies. In a fabric network, the APIC must be attached to the leaf nodes, as the leaf nodes are responsible for connecting end devices to the fabric network. Therefore, verifying that the APIC is attached to the leaf nodes is critical in troubleshooting fabric discovery failure.
E. Leaf nodes must connect to spine nodes only: In a Cisco Data Center fabric network, switches and nodes are connected through a hierarchical topology, where the leaf nodes are connected to the spine nodes only. The spine nodes act as the backbone of the fabric network and are responsible for forwarding traffic between the leaf nodes. Therefore, verifying that the leaf nodes are connected to the spine nodes only is essential in troubleshooting fabric discovery failure.
Therefore, the correct answers are B and E.
A. A Cisco APIC must be attached to a spine node only is incorrect, as the APIC should be attached to leaf nodes. C. Spine nodes must connect to other spine nodes is incorrect, as the spine nodes should only connect to leaf nodes. D. A Cisco APIC must be dual-attached to two separate spine nodes is incorrect, as the APIC should be attached to leaf nodes, not spine nodes.
