10.4 Queue Setup
Click Network Setting > QoS > Queue Setup to open the screen as shown next.
Use this screen to configure QoS queue assignment to decide the priority on WAN/LAN interfaces. Traffic
with higher priority gets through faster than those with lower priority. Low-priority traffic is dropped first
when the network is congested.
Note: Apart from the default entry that cannot be edited, you can add up to 6 extra entries.
Note: Configure the priority level for a QoS queue from 1 to 8. The smaller the number in the
Priority column, the higher the priority.
Note: The corresponding classifier(s) will be removed automatically if a queue is deleted.
Note: Rate limit 0 means there is no rate limit on a queue.
Note: Priority level 1 is the highest priority for QoS.

Upstream traffic
priority Assigned
by
Select how the Zyxel Device assigns priorities to various upstream traffic flows.
• None: Disables auto priority mapping and has the Zyxel Device put packets into the queues
according to your classification rules. Traffic which does not match any of the classification
rules is mapped into the default queue with the lowest priority.
• Ethernet Priority: Automatically assign priority based on the IEEE 802.1p priority level.
• IP Precedence: Automatically assign priority based on the first three bits of the TOS field in the
IP header.
• Packet Length: Automatically assign priority based on the packet size. Smaller packets get
higher priority since control, signaling, VoIP, Internet gaming, or other real-time packets are
usually small while larger packets are usually best effort data packets like file transfers.
