Abstract
A packet is received via a port of the network device, and a database lookup is performed using header information of the packet. A priority associated with the packet is determined, and it is determined whether the priority is associated with a particular communication protocol that provides guaranteed delivery, defined latency, and/or defined throughput. When it is determined that the priority is associated with the particular communication protocol, i) it is determined, based on the database lookup, whether a destination address (DA) of the packet is associated with the particular communication protocol, and ii) when it is determined that the DA of the packet is associated with the particular communication protocol, the packet is prevented from egressing from ports of the network device that are operating according to the particular communication protocol with a frame priority indicator corresponding to a value reserved for the particular communication protocol.
