Operation Manual – Port Basic ConfigurationH3C S5600 Series Ethernet Switches Chapter 1 Port Basic Configuration1-3Note:z Only combo optical ports on the front panel of the device support theauto-negotiation speed configuration feature. And ports on the extended interfacecard do not support this feature currently.z After you configure auto-negotiation speed(s) for a port, if you execute the undospeed command or the speed auto command, the auto-negotiation speed settingof the port restores to the default setting.z The effect of executing speed auto 10 100 1000 equals to that of executing speedauto, that is, the port is configured to support all the auto-negotiation speeds: 10Mbps, 100 Mbps, and 1000 Mbps.1.1.3 Limiting Traffic on individual PortsBy performing the following configurations, you can limit different types of incomingtraffic on individual ports. When a type of incoming traffic exceeds the threshold you set,the system drops the packets exceeding the traffic limit to reduce the traffic ratio of thistype to the reasonable range, so as to keep normal network service.Follow these steps to limit traffic on port:To do... Use the command...
