Configuring Port Trunks

Port trunks can be used to increase the bandwidth of a network connection or to ensure fault recovery. You can configure up to four trunk connections (combining 2~4 ports into a fat pipe) between any two VH-8G switches. However, before making any physical connections between devices, use the Trunk Configuration menu to specify the trunk on the devices at both ends. When using a port trunk, note that:

•Ports can only be assigned to one trunk.

•The ports at both ends of a connection must be configured as trunk ports.

•The ports at both ends of a trunk must be configured in an identical manner, including duplex mode, and VLAN assignments.

•None of the ports in a trunk can be configured as a mirror source port or mirror target port.

•All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from a VLAN.

•The Spanning Tree Algorithm will treat all the ports in a trunk as a whole.

•Enable the trunk prior to connecting any cable between the switches to avoid creating a loop.

•Disconnect all trunk port cables or disable the trunk ports before removing a port trunk to avoid creating a loop.
