Abstract

An example embodiment includes a network element. The network element includes an ingress port, an ingress line card, a link aggregation group (LAG) including multiple egress ports, and a distributor. The ingress port receives multiple packets including flood traffic. The ingress line card separates the packets into buckets. The distributor is configured to allocate the buckets to the egress ports, transmit the buckets to the egress ports, and when a failed egress port is identified, reallocate the buckets from the failed egress port to at least one functional egress port while continuing to transmit the buckets to functional egress ports of the LAG.
