Forwarding table generation including override configuration

Abstract

In one embodiment, a network switch device includes a network interface comprising ingress ports and egress ports, and configured to receive forwarding-table-configuration packets from a network management node, a processor to form a forwarding table based on the received forwarding-table-configuration packets, generate a forwarding-table-override configuration for a given ingress port of the ingress ports to override at least one forwarding rule of the forwarding table for the given ingress port, and install the forwarding table and the forwarding-table-override configuration for use by the given ingress port, and forwarding circuitry to forward packets received at the given ingress port based on the forwarding table overridden by the forwarding-table-override configuration.

Dependencies are inferred from the claim text.
