D: the Aruba 6400 switch series does not support high-availability with dual-control planes. The Aruba 6400 series switches are fixed-configuration switches designed for access and aggregation deployments in campus networks. While they offer advanced features and performance, including support for 10GbE and 40GbE interfaces, they do not incorporate dual-control planes for redundancy and high availability.
However, Aruba offers other switch series, such as the Aruba 5400R zl2 and Aruba 8400, that do provide dual-control planes for enhanced resiliency. These series are typically targeted for more demanding network environments where high availability and redundancy are critical.
If you require high availability and dual-control planes, it is recommended to consider the Aruba 5400R zl2 or Aruba 8400 series switches or consult the official Aruba documentation to explore other switch models that meet your specific requirements.
