Command: setup qos vlanTagPri <0~7> <0~3>
Message: Please input the following information.
VLAN TAG index <0~7>: 0
Queue index (ENTER for default) <1>: 1
-----------------------------------------------------------------------------
Set up queue index(0, 1, 2 or 3) on each Priority of VLAN Tag.
VLAN Tag Priority uses the tag field information which has been inserted into an Ethernet frame. If a port has
an 802.1Q-compliant device attached (such as this modem), these tagged frames can carry VLAN
membership information.
User priority is giving eight priority levels. The default value is 0, indicating normal treatment.
Priority Level Traffic Type
0 (default) Best Effort
1 Background
2 Spare
3 Excellent Effort
4 Controlled Load
5 Video, less than 100 milliseconds latency and jitter
6 Voice, less than 10 milliseconds latency and jitter
7 Network Control
Each Priority level can be set queue index from 0 to 3.
For example, you can set the EFM modem use Weighted Round-Robin (WRR) queuing (Type 1) that
specifies a relative weight of each queue. WRR uses a predefined relative weight for each queue that
determines the percentage of service time to services each queue before moving on to the next queue.
VLAN Tag Priority QoS:
VLAN Tag Index 0 1 2 3 4 5 6 7
Queue Index
4.4.4.7 IP DSCP Priority Qos
Differentiated Services (DiffServ) is a class of service (QoS) model that enhances best-effort Internet services
by differentiating traffic by users, service requirements and other criteria. Packet are specifically marked,
allowing network nodes to provide different levels of service, as appropriate for video playback, voice calls or
other delay-sensitive applications, via priority queuing or bandwidth allocation.
The DSCP value used to identify 64 levels of service determines the forwarding behavior that each packet
gets across the DiffServ network. Based on the marking rule different kinds of traffic can be marked for
