Trunk Configuration
Trunk allows the switch to combine ports so that they function like a single high-
speed link. It can be used to increase the bandwidth to some devices to provide a
high-speed link. For example, trunk is useful when making connections between
switches or connecting servers to the switch. Trunk can also provide a redundant link
for fault tolerance. If one link in the trunk failed, the switch can balance the traffic
among the remaining links.
NOTE: The 10/100 Mbps port cannot be trunked with gigabit port (port 25~26). All
ports in the same trunk group will be treated as a single port. If a trunk group exists,
the ports belonging to that trunk will be replaced by "TRUNK #" in the VLAN
configuration screen. The following example configures port 25~26 as "TRUNK 1."
