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 trunking ports
composes one trunk. Two switch units can be cascaded through one
trunk. The aggregated bandwidth of one trunk can be up to 400Mbps, if
2 trunking ports are used for one trunk.
The switch supports the following trunk configurations:
Configuration Trunk Trunking ports
1 None None
2 1 Trunk [Port 1, Port 2]
3 1 Trunk [Port 7, Port 8]
4 2 Trunk1 [Port 1, Port 2]
Trunk2 [Port 7, Port 8]
Refer to Console (Telnet) management chapter and Web management
chapter for more information about how to configure a data port as a
trunking port.
