9.2 Bandwidth Control

Bandwidth function, allowing you to control the traffic rate and broadcast flow on each port to
ensure network in working order, can be implemented on Rate Limit and Storm Control pages.

9.2.1 Rate Limit

Rate limit functions to control the ingress/egress traffic rate on each port via configuring the
available bandwidth of each port. In this way, the network bandwidth can be reasonably distributed
and utilized.
Choose the menu QoS→Bandwidth Control→Rate Limit to load the following page.
Strict-Priority + Weight Round Robin Mode. In this mode, this switch
provides two scheduling groups, SP group and WRR group. Queues
in SP group and WRR group are scheduled strictly based on
strict-priority mode while the queues inside WRR group follow the
WRR mode. In SP+WRR mode, TC3 is in the SP group; TC0, TC1
and TC2 belong to the WRR group and the weight value ratio of
TC0, TC1 and TC2 is 1:2:4. In this way, when scheduling queues,
the switch allows TC3 to occupy the whole bandwidth following the
SP mode and the TC0, TC1 and TC2 in the WRR group will take up
the bandwidth according to their ratio 1:2:4.
Equal-Mode. In this mode, all the queues occupy the bandwidth
equally. The weight value ratio of all the queues is 1:1:1:1.
