The best practices for configuring NIC teaming load balancing for Cisco UCS B-Series blades
connected to Cisco ACI leaf switches involve enabling LACP (Link Aggregation Control Protocol) in
active mode and enabling MAC pinning.
LACP active mode (option B) allows for the automatic bundling of several physical links into a single
logical link, providing redundancy and increased bandwidth. This mode actively tests the link to
ensure its functionality, which is essential for maintaining a stable connection.
MAC pinning (option E) is a method that assigns a virtual machine’s MAC address to a specific uplink.
This ensures consistent forwarding paths for traffic within the same session, which is crucial for
avoiding potential traffic distribution issues that could arise from dynamic changes in the network
topology.
Creating vPC+ (option A) and vPC (option D) are not recommended as they are related to virtual port
channels, which are not applicable in this scenario. PAgP (Port Aggregation Protocol) (option C) is
Cisco’s proprietary protocol similar to LACP, but it is not the recommended practice in this context.
