Rate Limit Configuration
This function allows the network manager to control the maximum rate
for traffic transmitted or received on a port. Rate limiting is configured on
ports at the edge of a network to limit traffic into or out of the network.
Traffic that falls within the rate limit is transmitted, while packets that
exceed the acceptable amount of traffic are dropped.
Rate limiting can be applied to individual ports. When a port is configured
with this feature, the traffic rate will be monitored by the hardware to
verify conformity. Non-conforming traffic is dropped, conforming traffic
is forwarded without any changes.
Fields and Attributes
•The rate range is:
• Fast Ethernet interface – 1 to 100 Mbps.
• Gigabit Ethernet interface – 1 to 1000 Mbps.
• Resolution – the unit increment of rate change:
• Fast Ethernet interface – 1 Mbps.
• Gigabit Ethernet interface – 8 Mbps
• The maximum data rate for VDSL ports depends on the physical link
and the selected EFM profile (see page 3-147.)
