3.4 Making Trunk Connections
Two switch units can be cascaded together through any regular switched
data port on each unit when a port expansion is required. However, the
transfer bandwidth between the two cascaded ports is limited to 200Mbps
full duplex. To increase the bandwidth for the connection between two
switch units, a trunking function is implemented on the switch unit for
this purpose. Normal data ports can be configured optionally as trunking
ports through the network management operation.
Two or more trunking ports composes one trunk. Two switch units can
be cascaded through one trunk. The aggregated bandwidth of one trunk
can be up to 1.6Gbps, if 8 trunking ports are used for one trunk.
Refer to the software operation manuals in the supplied CD-ROM for
more information about how to configure a data port as a trunking port.
The following figure illustrates an example of 4-port trunk connection
between switch A and switch B. The Port 3, 4, 5 and 6 of switch A are
configured as trunking ports and compose one trunk. The Port 5, 6, 7, and
8 of switch B are configured as trunking ports and compose one trunk.
The aggregated bandwidth of the trunk is 800Mbps.
