Abstract: An MC-LAG system may operate to monitor load conditions existing in two network switches, and to compute a load index value based on detected load conditions. If a computed load index value for a first switch is determined to exceed a predetermined threshold, an overloaded switch may predictively cause traffic to be routed to a second switch prior to rebooting of the first switch. Load index values may be computed based upon factors including excessive inter-switch link (“ISL”) flapping, excessive MAC flush or MAC move operations in a switch, excessive processing resource utilization in a switch.

Abstract: A switch includes a port and a processor to receive an event associated with unblocking of the port. In response to the event associated with the unblocking of the port, the processor is to wait a specified amount of time that is based on a loop detect time interval used by a loop protect process for detecting a loop in a network. After waiting the specified amount of time, the processor is to determine whether the port remains unblocked.

Abstract: A method for convergence of multicast traffic in response to a topology change. The method includes, in response to a change in a multicast topology, redirecting multicast traffic through a network device of a plurality of network devices in the multicast topology and determining a querier status of the network device. The method also includes flooding the multicast traffic through an interface to the network device to facilitate convergence of the multicast traffic. The interface is a connecting point between the network device and another network device of the plurality of network devices.
