Figure 77: Configuring Ingress Port Tag Classification

CONFIGURING PORT

POLICIERS

Use the QoS Ingress Port Policers page to limit the bandwidth of frames

entering the ingress queue. This function allows the network manager to

control the maximum rate for traffic received on an port. Port policing is

configured on interfaces at the edge of a network to limit traffic into of the

network. Packets that exceed the acceptable amount of traffic are dropped.

Port policing can be applied to individual ports. When an 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.

PARAMETERS

These parameters are displayed:

◆ Port – Port identifier.

◆ Enabled – Enables or disables port policing on a port.

◆ Rate – Controls the maximum rate for frames entering the ingress

queue for a port. (Range: 100-1,000,000 kbps/fps, 1-3.300 Mbps/kfps;

Default: 500 for all units of measure)

◆ Unit – Controls the unit of measure for the policer rate as kbps, Mbps,

fps or kfps. The default value is kbps.

◆ Flow Control – If flow control is enabled and the port is in flow control

mode, then pause frames are sent instead of discarding frames.
