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 9 and Port 10).
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 1~ Port 2 as “TRUNK 1.”
