Advanced > Port Trunking
Port Trunking is a feature that allows multiple links between switches to work as one virtual link (aggregate link). Trunks can be defined for similar
port types only. For example, a 10/100/1000 port cannot form a Port Trunk with a GBIC port. Up to four trunks can be enabled at the same time.
To set up a trunk, use the pointer to select the ports that will participate in the trunk. Spanning Tree will treat trunked ports as a single virtual port.
