What is sifIndex?
This read-only INTEGER identifies the port number, beginning with 1 for the first port. An administrator uses it as the key that ties every other per-port sif* value, such as sifState or sifCongested, back to a specific physical port. For example, the admin reads sifIndex alongside sifCongested to confirm exactly which physical port, port 4, is the one reporting outbound congestion.
