Abstract
Various embodiments of the invention provide systems, devices, and methods of configuring and controlling the operation of fallback links within a network. In certain embodiments, this is accomplished by selecting an operationally active port and internally configuring it to be part of an uplink LAG to achieve minimal L2 connectivity. Compared with existing designs, the presented invention has reduced delay time, minimal impact on network traffic, increased fallback bandwidth, faster convergence, and prevents link flaps of downstream server ports. In line with the IOA's plug- and play philosophy, no administrator intervention or reprogramming of VLANs is required in selecting fallback links.
