Abstract
A stacked switch includes two or more individual network switches connected to each other in a ring or daisy chain topology over stacking links, and at least one port on two or more of the individual switches comprising the stacked switch is a member of a LAG configured on the stacked switch. Each of the individual switches comprising the stacked switch include control plane and data plane functionality that operates to maintain switching tables and to process network data ingressing to the switch to determine how to forward the network data through the switch to an egress point. The control functionality included in each of the switches comprising the stacked switch also includes an enhanced ECMP functionality that operates to optimize the use of stacking link bandwidth on the stacking links connecting the two or more individual switches to each other.
