Chapter 2 Configuring General Switch Features
Configuring PNNI Node Parameters
Configuring PNNI Node Parameters
The Cisco MGX 8850 and Cisco MGX 8950 switches support many PNNI configuration commands.
This section describes how to configure the basic PNNI configuration parameters for the switch.
Chapter 6, “Managing PNNI Nodes and PNNI Routing,” describes how to manage PNNI after you have
brought up the PNNI node.
Caution It is important to configure the PNNI node parameters before you start creating SPVCs as described in
Chapter 6, “Provisioning AXSM Communication Links.” If you create SPVCs using the default PNNI
node parameters and later change those parameters, the node will advertise the old ATM address
information for the older SPVCs as well as the new ATM address information. To keep PNNI running at
maximum efficiency, set the PNNI node parameters to the proper values before creating SPVCs, or
delete and recreate old SPVCs after making PNNI node parameter updates.
Adding the PNNI Controller
The PNNI controller simplifies switch configuration by using PNNI protocol to discover call routes in
an ATM network. Without the PNNI controller, each route through the network would have to be defined
manually or through an alternative routing mechanism such as MPLS. Chapter 6, “Managing PNNI
Nodes and PNNI Routing,” provides more information on PNNI. This section describes how to enable
and configure the PNNI controller for the switch.
Note Before entering the following command, you must log in as a user with SUPER_GP privileges or higher.
To enable and configure the PNNI controller, enter the following command:
8850_LA.7.PXM.a > addcontroller <cntrlrId> i <cntrlrType> <slot> [cntrlrName]
Table 2-6 describes the parameters for the addcontroller command.
Tip Remember to include the i option, which identifies the controller as an internal controller.
Table 2-6 Parameter Descriptions for the addcontroller Command
Parameter Values Descriptions
cntrlrId 2 Controller ID. Enter 2 to specify a PNNI controller or 3 to specify an
MPLS controller. The MPLS controller is introduced in the next section.
— i Enter the value i. This parameter will support additional values in future
releases.
cntrlrType 2 or 3 Controller type. Enter 2 to specify a PNNI controller or 3 to specify an
MPLS controller. The MPLS controller is introduced in the next section.
