schedul
ing. The switch will control the forwarding sequence of the packets according to the priority
queues and scheduling algorithms you set. On this switch, the priority levels are labeled as TC0,
TC1… TC3.

Figure 9-7 Schedule Mode
The following entries are displayed on this screen:
 Schedule Mode Config
SP-Mode: Strict-Priority Mode. In this mode, the queue with higher priority
will occupy the whole bandwidth. Packets in the queue with lower
priority are sent only when the queue with higher priority is empty.
WRR-Mode: Weight Round Robin Mode. In this mode, packets in all the
queues are sent in order based on the weight value for each
queue. The weight value ratio of TC0, TC1, TC2 and TC3 is
1:2:4:8.
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.
9.1.3 802.1P Priority
On this page you can configure 802.1P priority. 802.1P gives the Pri field in 802.1Q tag a
recommended definition. This field is used to divide packets into 8 priorities. When 802.1P Priority is
enabled, the packets with 802.1Q tag are mapped to different priority levels based on 802.1P priority
mode. The untagged packets are mapped based on port priority mode.
Choose the menu QoS→DiffServ→802.1P Priority to load the following page.
