Conguring Port-Based Rate Policing
If the interface is a member of a VLAN, you may specify the VLAN for which ingress packets are policed.
• Rate policing ingress trac on an interface.

Conguring Port-Based Rate Shaping
Rate shaping buers, rather than drops, trac exceeding the specied rate until the buer is exhausted. If any stream exceeds the
congured bandwidth on a continuous basis, it can consume all of the buer space that is allocated to the port.
Dell Networking OS Behavior: Rate shaping is eectively rate limiting because of its smaller buer size. Rate shaping on tagged ports is
slightly greater than the congured rate and rate shaping on untagged ports is slightly less than congured rate.
Rate shaping buers, rather than drops, trac exceeding the specied rate until the buer is exhausted. If any stream exceeds the
congured bandwidth on a continuous basis, it can consume all of the buer space that is allocated to the port.
