 For a blade server that lacks support of bonding, the port channel mode that results in “route based on originating virtual port” on the VMware VDS is MAC Pinning-Physical-NIC-load (Option B). This mode ensures that the virtual machine traffic is distributed across the available uplinks based on the MAC address of the originating virtual port1.

In a Cisco ACI bridge domain and VRF configured with a default data-plane learning configuration, the two endpoint attributes that are programmed in the leaf switch when receiving traffic are:

Local MAC, IP (Option D)5.

Local Subnet (Option E)5. These attributes are learned by the ACI fabric through common network methods such as ARP, GARP, and ND, as well as through the data-plane. The local MAC and IP addresses are learned and used for traffic routing and bridging, while the local subnet information is used for traffic optimization and endpoint location tracking56.

To prevent frequent MAC and IP address moves between different leaf switch ports, enabling rogue endpoint control is the recommended action. This feature helps in identifying and mitigating the movement of endpoints that could potentially cause loops or other issues within the network.
