After choosing “Add”, you will see the bandwidth allocation settings window. In this window there are the following fields:
You can check what values are acceptible when you place the cursor on the field, or you can choose a value from the drop-down list containing the objects that are already known to ICS CUBE. Bandwidth allocation is a QoS (quality of service) tool, it is used, for example, to reserve a communication channel, for example, for qualitative IP-telephony the necessary bandwidth allocation and IP-telephony ports need to be set up, and the rule should be assign to approptiate users.
When you mark the “use the bandwidth allocation of a parent” checkbox, traffic set in the rule, can use bigger bandwidth then it's set in the rule, if the channel is free.
The “priority” field works when the channel is overloaded: the most prioritized traffic goes first.
