Ethernet Port Configuration Commands 49 Ethernet Port Configuration Commands This section describes the commands you can use to configure and manage the ports on your Switch 5500G-EI. broadcast-suppression Syntax broadcast-suppression { ratio | pps pps } undo broadcast-suppression View Ethernet Port View Parameter ratio: Specifies the bandwidth ratio of broadcast traffic allowed on an Ethernet port. The ratio value ranges from 1 to 100. The incremental step is 1. By default, the ratio is 100 meaning all broadcast traffic is accepted. The smaller the ratio is, the less bandwidth is allocated to broadcast traffic and therefore less broadcast traffic is accepted on the Ethernet port. pps pps: Specifies the maximum number of broadcast packets per second accepted on an Ethernet port. Ranges from 1 to 148810 pps. Description Use broadcast-suppression to configure the amount of broadcast traffic that will be accepted on a port. Once the broadcast traffic exceeds the value set by the user, the excess broadcast traffic will be discarded. This feature can be used to ensure network service and prevent broadcast storms. Example Enable a limit of 20% of the available bandwidth on a port to be allocated to broadcast traffic. Broadcast traffic exceeding 20% of the ports bandwidth will be discarded. system-view System View: return to User View with Ctrl+Z.
