Rate Control
Rate limiting is a form of flow control that is used to enforce a strict bandwidth limit at a port. You
can program separate transmit (egress) and receive (ingress) rate limits at each port, and even
apply the limit to certain packet types as described below.
Limit packet type
: You can select the packet type that you want to be filtered. The packet types
listed here include broadcast/multicast/unknown unicast packets, broadcast/multicast packets,
and broadcast only packets. The broadcast/multicast/unknown unicast packet,
broadcast/multicast packet, and broadcast packet only are only for ingress packets (incoming
packets). The egress (outgoing) rate only supports “All” packet types.
Bandwidth
: Ports 1-8 support port ingress (incoming traffic) and egress (outgoing traffic) rate
controls. For example, let’s assume port 1 is at 10Mbps--you can set its effective transmit/egress
rate to be 1Mbps, and receive/ingress rate to be 500 Kbps. The switch then uses the packet
counter to control the number of packets coming in so that the configured ingress rate can be
achieved.
Ingress:
Select the ports effective ingress rate here. Valid values are 1Mbps, 2Mbps, 4Mbps,
8Mbps, 16Mbps, 32Mbps and 64Mbps. The default value is “disable”.
Egress:
Select the ports effective egress rate here. Valid values are 128kbps, 256Kbps,
512Kbps, 1Mbps, 2Mbps, 4Mbps, and 8Mbps. The default value is “disable”.

Note:
Always remember to click on the
Save Configuration
button to save your settings.
Otherwise, the settings you made will be lost when the switch is powered off.
IMPORTANT
: Both QoS and Rate Control settings cannot exist at the same time.
