Setting The Ethernet Port Broadcast Suppression Ratio; Enabling Flow Control On A Port - Huawei Quidway S3100 Series Operation Manual

Operation Manual – Port
Quidway S3100 Series Ethernet Switches

1.2.2 Setting the Ethernet Port Broadcast Suppression Ratio

You can use the broadcast-suppression commands to restrict the broadcast traffic
allowed to pass through a port. After that, if the broadcast traffic on the port exceeds the
value you set, the system will maintain an appropriate broadcast traffic ratio by
discarding the overflow traffic, so as to suppress broadcast storm, avoid network
congestion and ensure normal network services.
You can execute the broadcast-suppression command in system view or Ethernet
port view:
If you execute the command in system view, the command takes effect on all
ports.
If you execute the command in Ethernet port view, the command takes effect only
on current port.

1.2.3 Enabling Flow Control on a Port

After flow control is enabled on both the local and the peer switches, if congestion
occurs on the local switch, the switch will inform its peer to suspend packet sending. In
this way, packet loss is reduced and normal network services are guaranteed.
