DUA1640-5AAA02Performing Load Balancing 4-32 The load balancing feature notes:n Any ports or segments that have been fixed — Throughmanagement you can fix ports and segments that you do not wantload balancing to move.n 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 beconsidered by the load balancing feature, when it works out whatother ports it will move.3 The load balancing feature works out how it can configure thesegments. It attempts to:n Have frequently communicating ports on the same segment.n Reduce the total traffic utilization across the segments.4 If some benefit will be gained from the new configuration, the loadbalancing feature completes the operation by moving the portsbetween the segments as required.Using an ExternalSwitchThe best way to interconnect the cascaded segments in a stack ofPS Hubs is to use a PS Hub 50. However, if you want to connect two ormore segments using an external switch, you must connect the switchto the PS Hub’s 10BASE-T or transceiver module ports and then portswitch those ports to the relevant segments.For information on using your switch, refer to the documentation thataccompanies it.Performing LoadBalancingYou can configure the load balancing feature through management(it is disabled by default). For information on initiating the loadbalancing feature using the web interface, refer to “Load Balancing”on page 7-20. For information on setting it up using the LoadBalancing Tool (which is launched from within Quick Config Manager),refer to “Load Balancing” on page B-18.
