CLI – Use the interface command to select the monitor port, then use the
port monitor command to specify the source port and traffic type.
Configuring Rate Limits
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 coming 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 or trunks. When an
interface 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.
Rate Limit Granularity
Rate limit granularity is an additional feature enabling the network manager
greater control over traffic on the network. The “rate limit granularity” is
multiplied by the “rate limit level” (page 3-114) to set the actual rate limit
for an interface. Granularity is a global setting that applies to Fast Ethernet
or Gigabit Ethernet interfaces.
Command Usage
• For Fast Ethernet interfaces, the rate limit granularity can be set to
8 Kbps, 64 Kbps, 512 Kbps, 1 Mbps, 2 Mbps, or 3.3 Mbps.
• For Gigabit Ethernet interfaces, the rate limit granularity can be set to
32 Kbps, 64 Kbps, 512 Kbps, 1 Mbps, 2 Mbps, 3.3 Mbps, 10 Mbps, or
33.3 Mbps.
