each switch. The reconciliation process ensures resiliency and minimal traffic disruption by verifying and

synchronizing the controller’s information with each switch in the active fabric. In case of traffic loss, the

controller resolves the data discrepancies on the switches by adding or removing flows.

Link Aggregation Control Protocol (LACP) and NIC

Teaming

To dynamically form an LACP logical group with extended connectivity from a single node to multiple

nodes, the controller uses LACP to respond to messages from external ports on external legacy networks

or servers connected using LACP. LACP enables the controller to dynamically aggregate multiple links as

a logical group while eliminating loops and duplicate packet generation inside the group. Port parameter

changes or link status changes are detected and synchronized with neighbors having updated members.

NOTE: All members of a LAG or port channel must be the same speed (1G, 10G, or 40G). Link speed

combinations are not supported.

The software automatically detects LACP-enabled external nodes. This extends connectivity from the

standard one-to-one LACP connection to multi-to-one LACP connection by exposing the virtual system

and port information when the external nodes configure LACP over multiple links as one group. The

group is terminated into multiple internal switch nodes and the internal switch nodes are directly

connected to each other.

The NIC teaming feature collects NIC teaming information from the orchestration tool and optimizes

traffic flow originating from or destined for NIC teaming. NIC teaming extends coverage of connectivity

to multiple internal switching nodes. The multi-node extension for LACP and NIC teaming allows traffic
