Configuring Port-Based Rate Shaping
Rate shaping buffers, rather than drops, traffic exceeding the specified rate until the buffer is exhausted. If any stream exceeds
the configured bandwidth on a continuous basis, it can consume all of the buffer space that is allocated to the port.
Dell Networking OS Behavior: Rate shaping is effectively rate limiting because of its smaller buffer size. Rate shaping on tagged
ports is slightly greater than the configured rate and rate shaping on untagged ports is slightly less than configured rate.
