NOTE: In the line-card CPU, some queues have no protocol trac mapped to them. These rows appear blank in the preceding
table.
CoPP Example
The illustrations in this section show the benet of using CoPP compared to not using CoPP on a switch.
The following illustration shows how CoPP rate limits protocol trac destined to the control-plane CPU.
Figure 26. Control Plane Policing
NOTE
: On the system, CoPP does not convert the input rate of control-plane trac 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.
The following illustration shows the dierence between using CoPP and not using CoPP on a switch.
