SWTGIGABIT/FAST ETHERNET SWITCH TYPE SWT 54/137USER GUIDE - M0SWTA1903Iv09 - V09 March 20195.6 BANDWIDTH LIMIT CONFIGURATIONThe Rate Control menu permits bandwidth limits to be established in each one of theports, both incoming and outgoing. The data volume limit may be established in general forall types of traffic, as well as for certain combinations that take into account the type ofmessages.The menu parameters are divided into two quite different blocks, which are:− Incoming bandwidth control to the port (Ingress Rate Control).− Outgoing bandwidth control from the port (Egress Rate Control).The configuration parameters of each block are indicated below.Ingress Rate Control:• #. It identifies the port number, and it coincides with the equipment connectornumber. The last four ports are always associated with the SFP ports.• Enable. This permits each port to be enabled or disabled individually, by ticking ornot ticking the respective Enable box.• Traffic. It specifies the type of traffic: all, broadcast (b), broadcast and multicast(bm) or broadcast, multicast and flooding (bmf).Broadcast refers to the diffusion messages, that is, the information transmissionmode where an emitting node sends information to all the receivers simultaneously.Multicast refers to the multi-diffusion messages, which are directed towards to themembers of a multi-diffusion group.Flooding refers to the situation when there is a flood in a short time, usually due toan incorrect topology, an inappropriate configuration, or a voluntary action by someclient equipment.• Rate (bps). It establishes the maximum incoming bandwidth to the port: 64000 bps(64 kbps) to 250000000 bps (250 Mbps). The maximum speed only affects theGigabit Ethernet ports.Egress Rate Control:• #. It identifies the port number, and it coincides with the equipment connectornumber. The last four ports are always associated with the SFP ports.• Enable. This permits each port to be enabled or disabled individually, by ticking ornot ticking the respective Enable box.
