In the top part of Figure 76 Port Setting are the egress queue settings for this port. This setting affects the
frames going out of the equipment.
In the middle in Figure 76 (with the complex heading) are the settings affecting the incoming (ingress)
frames to this port, i.e. opposite direction from the setting above.
Lower part in Figure 76 (Egress Class Setting Information) describes again queue settings affecting egress
frames queuing out of the equipment to this Ethernet port.
In most cases the bottle-neck is the modem. In that case only the middle part of the Ethernet QoS port
setting (the ingress frame mapping) has any real effect. Correspondingly the modem queue settings are
crucial.
QOS SETTINGS SUMMARY
After repeating the settings for all ports the Port Setting summary looks as Figure 77.
Figure 77. Summary of QoS settings.
In this case the mapping is identical and all the QoS settings for all ports are identical except for the modem
Egress Shaper rate which depends on the Channel Spacing and current Modulation.
