SP+WRR-Mode: 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.
Equ-Mode: 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.
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.
