displays the local port condition as Unbalanced.
2 Select the Controller folder icon.
3 From the shortcut menu, select Rebalance Local Ports.
To clear the automatic reminder from System Manager to rebalance local ports, in the
Rebalance Local Ports window, select or clear Check for unbalanced local ports at Startup.
Note System access is restricted while the rebalancing process is in progress.
