The following illustration shows the difference between using CoPP and not using CoPP on a switch.
Figure 28. CoPP Versus Non-CoPP Operation
NOTE:
On the Z9500, CoPP does not convert the input rate of control-plane traffic from kilobits per second (kbps) to packets per
second (pps) as on other Dell Networking switches. On other switch, CoPP converts the input kilobit-per-second rate to a
packet-per-second rate, assuming 64 bytes as the average packet size. CoPP then applies the packet-per-second rate to
the appropriate queue. On these switches, 1 kbps is approximately equal to 2 pps.
Configure Control Plane Policing
You can create a CoPP service policy on a per-protocol and/or a per-queue basis that serves as the system-wide configuration
for filtering and rate limiting control-plane traffic.
Configuring CoPP for Protocols
This section lists the commands necessary to create and enable the service-policies for CoPP.
