How the Resource Manager Works with ST2
The following summarizes the exchange between the ST2 agent and the Resource
Manager :
1. The router receives an ST2 connect request.
The ST2 connect request includes a flow specification (flowspec) that
indicates the resources needed to meet the QoS.
2. ST2 passes the flowspec to the Resource Manager.
3. The Resource Manager compares the requested resources with available
reservable bandwidth.
Resource Manager determines reservable bandwidth from configured values
described later in this chapter. It also accounts for any active reserved flows.
4. The Resource Manager either reserves the necessary services or refuses
service.
Starting the Resource Manager
To enable the Resource Manager for reserving and allocating bandwidth:
1. Start at the Configuration Manager window.
2. Click on the circuit connector.
Select any XCVR (10-Mb/s or 100-Mb/s Ethernet), HSSI, MCT1, or COM
connector for a line that is configured for ST2.
3. Unless you selected an MCT1 connector, go to Step 6.
The MCT1 Logical Lines window appears (F
igure 6-1).
Note: Before you can enable the Resource Manager, you must first configure
IP and the ST2 agent on a circuit.
