4-2-8. Quality of Service Configuration

The switch offers powerful QoS function. This function supports VLAN-tagged priority that can make precedence of 8 priorities, TOS field of IP header (equal DSCP High 3 bits) on Layer 3 of network framework, 6 kinds of special network transmission events on Layer 4 and IP DiffServe QoS service.

In Quality of Service (QoS) Configuration, there is one option named” Default Class”. As you had selected one of the four QoS functions, then some packets that did not belong to this QoS would be viewed as Default Class. For instance, if you set QoS function as VLAN Tag Priority mode, and then choose Default Class a s High, finally, the priority of the packets with no tag will be considered as High priority precedence. The initial value of the Default Class is High.

Function name:

VLAN Tag Priority

Function description:

In vlan tag, there are 3 bits belonging to priority. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0, 1 1 1. We can set High priority or Low priority for each traffic class. For instance, if we let VLAN-tagged priority 0 0 0 be high priority and VLAN-tagged priority 0 0 1 be Low Priority, and then make port 1, 2, 3 be in the vlan 2. We sent in the packets that have vlan-tagged Field appears 0 0 0 and VID equals 2 from the port 2 and the packets that have vlan-tagged Field appears 0 0 1 and VID equals 2 from the port 3. We let the two kinds of packets be transmitted for port 1 until the port results in congestion. The result is that the packets will be dropped partially from the port 3 because the packets that belong to Low Priority. For the use of VLAN Tag Priority function, please press Configure at the right section for setting in advance.
