Figure 3-5 Relationship of Port Controller, Controller Partition, and Resource Partitions
Figure 3-5 shows that the single controller partition connects to the port controller and to the resource
partitions. Note that the port controller and the controller partition both reside on the PXM1E card.
After you create a port, you must create a resource partition for that port, select the PNNI controller, and
define which ATM resources the port will use. You do not have to create the controller partition, as it is
automatically created when you create the first resource partition. It is important that the same controller
partition, and therefore the same partition ID, be used for all resource partitions of the same type on the
same PXM1E card. For example, the controller is identified by the controller ID and the controller
partition is identified by the partition ID. The resource partitions are identified by specifying the
partition ID in combination with the port ID (interface number).
To create a resource partition for a port, use the following procedure.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Note You must add the PNNI controller and add a port before you create a resource partition for a port.
For instructions on adding the controller, see the “Adding the PNNI Controller” section in
Chapter 2, “Configuring General Switch Features.” For instructions on adding ports, see the
“Adding ATM Ports” section earlier in this chapter.
Step 2 Determine the port number to which you want to assign the resource partition. To display a list of the
ports, enter the following command:
mgx8830a.1.PXM.a > dspports
This command displays all ports on the PXM1E card in the ifNum (interface number) column.
Step 3 To create a resource partition, enter the following command:
mgx8830a.1.PXM.a > addpart <ifNum> <partId> <ctrlrId> <egrminbw> <egrmaxbw> <ingminbw>
<ingmaxbw> <minVpi> <maxVpi> <minVci> <maxVci> <minConns> <maxConns>
Table 3-10 describes the parameters for this command.
