In a two-pod Cisco ACI Multi-Pod environment, it is recommended to deploy no more than two Cisco APIC controllers in the same pod to avoid losing all replicas of a shard if a pod fails. The APIC cluster is a distributed system where each APIC contains a replica of the configuration database, referred to as a shard. If all replicas of a shard were located in the same pod and that pod were to fail, it would result in the loss of the shard and potentially impact the entire fabric’s operation. By distributing the APIC controllers across pods, the risk of losing all replicas due to a single point of failure is mitigated, enhancing the overall resiliency of the system1.

To integrate the VMware vCenter cluster with Cisco ACI and ensure that the management traffic of the hypervisors and VM controllers uses the virtual switch associated with the Cisco Application Policy, the following steps must be taken:

Enable Infrastructure VLAN on AAEP used toward VMware hypervisors: This step involves enabling the infrastructure VLAN on the Attachable Access Entity Profile (AAEP) that is used for the VMware hypervisors. This VLAN is used for carrying infrastructure traffic such as management, vMotion, and fault tolerance.

Create a static binding in the target EPG toward VMware hypervisors with VLAN 300: This step involves creating a static binding in the “Vmware-MGMT” EPG for the VMware hypervisors with VLAN 300, setting it as an untagged access VLAN, and using Untagged 802.1P mode. This ensures that the management traffic is correctly tagged and associated with the appropriate EPG.

To set Layer 2 loop migration in an ACI Fabric with a Layer 2 Out configured, MCP (Misconfiguration Protocol) must be enabled on the ACI fabric56. MCP helps to prevent Layer 2 loops by detecting misconfigurations that could potentially cause loops56.
