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.
