Configuring 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 traffic on an interface.

Example of the rate police Command
The following example shows configuring rate policing.
Dell#configure terminal
Dell(conf)#interface gigabitethernet 1/1
Dell(conf-if-gi-1/1)#rate police 100 40 peak 150 50
Dell(conf-if-gi-1/1)#end
Dell#show interfaces gigabitEthernet 1/2 rate police

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.

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.
