The Quality of Service (QoS) menu groups together multiple options of manipulating user data flow.
Ingress policing
Fig. 6.9: Configuration menu Settings – QoS
Ingress policing – causes user data flow to be limitted to certain value. The excessive packets are
discarded.
Ingress policing Enable Ingress policing. Applies to the device user port.
Speed [Mbps] Data rate to limit the Ethernet traffic to. If this speed is exceeded, Flow control
is initiated. If packets are still incoming, they are dropped.
Mode Ingress policer operation mode:
•
soft – Flow control is activated at low fill of input buffer. Good to use if the
connected device has Flow control enabled and has a large buffer.
• default – Universal settings. Close to “hard” settings, but with Flow control
enabled at connected device, packet loss is not possible.
• hard – Flow control is activated only after the input buffer is completely full.
Good to use if the connected device has a small buffer.
Warning
The Ingress policing activation deactivates the switch QoS functions.
