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.
INTERFACE mode
rate police
Example of the rate police Command
The following example shows conguring rate policing.
DellEMC#configure terminal
DellEMC(conf)#interface tengigabitethernet 1/1/1
DellEMC(conf-if-te-1/1/1)#rate police 100 40 peak 150 50
DellEMC(conf-if-te-1/1/1)#end
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 EMC 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.

• Apply rate shaping to outgoing trac on a port.

• Apply rate shaping to a queue.

Example of rate shape Command
DellEMC#configure terminal
DellEMC(conf)#interface tengigabitethernet 1/1/1
DellEMC(conf-if-te-1/1/1)#rate shape 500 50
DellEMC(conf-if-te-1/1/1)#end
