ensure there is overhead free in case there is total saturation of the scheduler.
If your egress throughput traffic rate on the Wan1_Uplink is 5 Mbps and you want to constrain it to
not exceed 3 Mbps. Set the Outbound QoS Bandwidth to 3Mbps to ensure that the aggregate
throughput upon the egress of the Wan1_Uplink doesn’t exceed your configured bandwidth.
Different traffic classes (Urgent, High, Normal, Low) sent on the same WAN uplink will share the
bandwidth at a ratio of (4:3:2:1) respectively. Their combined bandwidth will not exceed the
configured rate.
If you configure an inbound policy as well as an outbound policy, it is rate limited independent of
the outbound policy.
