The unique identifier of an ACI object is represented by the universal resource identifier (URI)2.

With unicast routing enabled on the bridge domain, the two conditions that enable the Cisco ACI leaf to learn a source IP as a local endpoint are:

Through Ethernet traffic received in a bridge domain (Option A): The leaf switch learns the source IP address as a local endpoint when it receives Ethernet traffic within the bridge domain.

Through ARP received on an SVI (Option E): The leaf switch also learns the source IP address as a local endpoint when it receives an ARP request or reply on a Switched Virtual Interface (SVI) associated with the bridge domain.

These conditions allow the ACI fabric to maintain an accurate endpoint database for efficient routing and forwarding of traffic within the fabric.

The type of port used for in-band management within ACI fabric is the spine switch port4.

Storm control should be configured on port channel on a single leaf switch (Option B) and endpoint-facing trunk interface (Option D) to protect against broadcast traffic6. These interfaces are where storm control policies are typically applied to prevent disruptions caused by traffic storms6.
