Configuring Port-Based Rate Shaping
Configuring port-based rate limiting is supported on the S4820T platform.
FTOS Behavior: Rate shaping is effectively rate limiting because of its smaller buffer size. On the S4820T, 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.
