To determine which user is responsible for the disappearance of a previously existing port group from vCenter, the engineer should check the EPG audit logs for any ‘deletion’ actions. By comparing the affected object and the user who performed the action, the engineer can identify the responsible individual2.

In Cisco ACI, when a packet is routed between two endpoints on different leaf switches, the VXLAN VNID that is applied to the packet corresponds to the Bridge Domain (BD). The BD VNID is used to encapsulate the packet for Layer 2 transport across the fabric. This VNID ensures that the packet is delivered to the correct bridge domain, maintaining the segmentation and policy enforcement required by the ACI fabric.

Cisco ACI Basic Configuration Guide

 When creating a subnet within a bridge domain in Cisco ACI, the configuration option used to specify the network visibility of the subnet is the scope12. The scope can be set to private, public, or shared, determining how the subnet is advertised and accessed within and outside of the ACI fabric12.

To complete the task of configuring a Layer 3 connection to the WAN router and allowing hosts in the production VRF to access WAN subnets, the engineer should configure the Export Route Control Subnet scope for the external EPG. This setting allows the subnets associated with the external EPG to be advertised to external routers, enabling connectivity to the WAN.
