Configuring Port-Based Rate Shaping
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.
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.
• Apply rate shaping to outgoing traffic on a port.
