6.4 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.

1.The 10/100 Mbps port cannot be trunked with gigabit port (port 25~26).

2.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.”
