Huawei AR1200-S User Manual

l Set the rate limit in pps for traffic suppression.
– Run the broadcast-suppression packets packets-per-second command to set the rate
limit in pps for broadcast traffic.
– Run the multicast-suppression packets packets-per-second command to set the rate
limit in pps for multicast traffic.
– Run the unicast-suppression packets packets-per-second command to set the rate limit
in pps for unknown unicast traffic.
NOTE
The SRU on the AR1200-S does not support the rate limit in pps. The rate limit in pps can be set on
LAN-side GE interfaces and LPU Ethernet interfaces.

4.4.1 Example for Setting the CIR Value for Traffic Suppression
This section describes how to set the CIR value for traffic suppression.
Networking Requirements
As shown in Figure 4-1, RouterA is connected to a Layer 2 network and a Layer 3 router. To
limit the number of broadcast, multicast, or unknown unicast packets forwarded on the Layer 2
network, you can set the rate limit in bit/s on Ethernet 0/0/0.
