2 The load balancing feature notes:
Any ports or segments that have been fixed — Through
management you can fix ports and segments that you do not want
load balancing to move.
Any ports that are connected to external switches.
These segments and ports will not be moved by load balancing.
However, traffic generated by these ports and segments will still be
considered by the load balancing feature, when it works out what
other ports it will move.
3 The load balancing feature works out how it can configure the
segments. It attempts to:
Have frequently communicating ports on the same segment.
Reduce the total traffic utilization across the segments.
4 If some benefit will be gained from the new configuration, the load
balancing feature completes the operation by moving the ports
between the segments as required.
The best way to interconnect the cascaded segments in a stack of
PS Hubs is to use a PS Hub 50. However, if you want to connect two or
more segments using an external switch, you must connect the switch
to the PS Hub's 10BASE-T or transceiver module ports and then port
switch those ports to the relevant segments.
For information on using your switch, refer to the documentation that
accompanies it.
You can configure the load balancing feature through management
(it is disabled by default). For information on initiating the load
balancing feature using the web interface, refer to "Load Balancing"
on page 7-20. For information on setting it up using the Load
Balancing Tool (which is launched from within Quick Config Manager),
refer to "Load Balancing" on page B-18.
