LABEL DESCRIPTION
LAN Managed
Downstream
Bandwidth Enter the amount of downstream bandwidth for the LAN interfaces (including WLAN) that
you want to allocate using QoS.
The recommendation is to set this speed to match the WAN interfaces’ actual transmission
speed. For example, set the LAN managed downstream bandwidth to 100000 kbps if you
use a 100 Mbps wired Ethernet WAN connection.
You can also set this number lower than the WAN interfaces’ actual transmission speed. This
will cause the Device to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the Device automatically sets this to the LAN interfaces’
maximum supported connection speed.
Upstream
traffic priority
Assigned by Select how the Device assigns priorities to various upstream traffic flows.
• None: Disables auto priority mapping and has the 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.
