Port Trunking
Port trunks can be used to increase the bandwidth of a network
connection or to ensure fault recovery. You can configure up to 6
trunk connections (combining 2 to 8 ports into a fat pipe) between
any two DES-3326 or other Layer 2 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:
•
The ports used in a trunk must all be of the same
media type (RJ-45, 100 Mbps fiber, or 1000 Mbps
fiber). The ports that can be assigned to the same
trunk have certain other restrictions (see below).
•
Ports can only be assigned to one trunk.
•
The ports at both ends of a connection must be
configured as trunk ports.
•
None of the ports in a trunk can be configured as a
mirror source port or a mirror target port.
•
All of 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 Protocol 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 data loop.
•
Disconnect all trunk port cables or disable the
trunk ports before removing a port trunk to avoid
creating a data loop.
Use the Port Trunking Configuration screen to set up port trunks
as shown below.
