inter-network. Actually, the link does not have an inherent total bandwidth equal to the sum
of its component physical links. Traffic in a trunk is distributed across an individual link
within the trunk in a deterministic method that called a hash algorithm. The hash algorithm
automatically applies load balancing to the ports in the trunk. A port failure within the trunk
group causes the network traffic to be directed to the remaining ports. Load balancing is
maintained whenever a link in a trunk is lost or returned to service. This switch may use
Port ID, Source MAC Address, Destination MAC Address, or a combination of Source MAC
Address and Destination MAC Address to be the selection for Trunk Hash Algorithm. Traffic
pattern on the network should be considered carefully before applying it. When a proper
hash algorithm is used, traffic is kind of randomly decided to be transmitted across either
link within the trunk and load balancing will be seen.
This managed switch supports two trunk group, each trunk consists of 2~4 ports. Trunk
hash algorithm can be selected according to 2 different methods.

4.23 QoS Setting

Here you can configure QoS policy priority mode and CoS (Class of Service) configuration.
QoS (Quality of Service) refers to mechanisms in the network software that make the actual
determination of which packets have priority. CoS refers to feature sets, or groups of
services, that are assigned to users based on company policy. If a feature set includes
