6.16 Ingress/Egress Rate Control
The rate control function limits the maximum traffic rate for each physical port. Traffic can
be ingress traffic or egress traffic. The rate control range is 64Kbps ~ 1000Mbps. The
following table describes the rule for the rate control setting.
Maximum Rate Rate Control Number (N) Rule
No Limit 0 0 means no limit.
64K,128K,192K…1792Kbps 1 ~ 28 Rate = N x 64Kbps
2M,3M,4M…100Mbps 29 ~ 127 Rate = (N-27) x 1Mbps
104M,112M…1000Mbps 128 ~ 240 Rate = (N-115) x 8Mbps
Table 6.2
For example, if you want to limit the download traffic rate of Port 3 to 512Kbps, set the
Egress Rate Control of Port 3 to 8 (8=512/64; egress is for download operation and ingress
is for upload operation).
The Packet Drop for Ingress Limit is used for packet dropping operation when ingress
traffic rate exceeds the Ingress Rate Control. If it is enabled, the extra packets will be
dropped to limit the ingress traffic rate. If it is disabled, the flow control function will be used
to pause the ingress traffic.
