PNNI UNI Port Configuration Quickstart
ATM UNI ports connect the switch to ATM end devices, which serve as the boundary between the ATM network and other communication paths or networks. Typical end devices include ATM routers and multiservice concentrators. UNI signaling is used between the end system (CPE) and the PNNI network for requesting calls.
The quickstart procedure in this section provides a summary of the tasks required to configure UNI ports on Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches. This procedure is provided as an overview and as a quick reference for those who have previously configured UNI ports.

Related commands:
dspports
dspilmis
Configure and start ILMI on the port. This step is required for dynamic addressing and the ILMI automatic configuration feature. Otherwise, it is optional.
See the "Configuring ILMI on a Port" section.
SVC Configuration Quickstart
Switched virtual circuits (SVCs) are the solution for on-demand connections. They are set up as needed and torn down when no longer needed. To enable this dynamic activity, SVCs use signaling. End systems request connectivity to other end systems and, provided that the requested services are available, the connection is set up at the time of the request. When idle, an SVC is taken down to save network bandwidth.
Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches can use the PNNI protocol to determine how to set up SVCs through the network. Because the switch automatically sets up SVCs, you do not have to configure SVC routes. However, the switch must be configured correctly before it can set up SVCs. The following quickstart procedure summarizes the tasks required to enable SVC communication. With the exception of CPE configuration, all these tasks are described in this chapter.
Note
Step 1
Configure the trunks that link the switches through which the ATM end stations connect. Be sure to add the PNNI controller on each switch and select that controller when partitioning trunks.
Step 2
dsppnni-reachable-addr network
At the PXM, verify connectivity between the node pairs that will host SVCs.
See the " Verifying End-to-End PNNI Communications" section in Chapter 6, "Card Management on MPSM-T3E3-155 and MPSM-16-T1E1."
Step 3
Configure UNI ports for the ATM end stations at each end of the SVC, and assign either static or dynamic addressing to each line. Be sure to add the PNNI controller on each switch and select that controller when partitioning trunks.
Step 4
See the CPE documentation.
Configure CPE devices for communication with the switch through the UNI ports configured in the previous step.
Step 5
dsppncons
This optional step displays the SVC connections that are operating. Enter this command on the active PXM.
It is beyond the scope of this guide to describe how to configure each model of CPE to communicate with the switch. To complete this configuration, you must learn the capabilities of the CPE and the switch and define a set of communication parameters that are supported by both devices. For example, the Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches support UNI 3.1 communication, but if the CPE does not, you must select a signaling protocol (such as UNI 3.0) that is supported by both devices.
After all requirements are met for SVC connections, CPE devices can establish SVC connections to other CPE devices on the same switched network.
SPVC and SPVP Configuration Quickstart
Soft permanent virtual circuits (SPVC) and soft permanent virtual paths (SPVP) are full-time circuits and paths that Private Network-to-Network Interface (PNNI) can reroute to avoid failed communication links or to utilize links that offer better bandwidth. SPVPs support multiple virtual circuits, whereas SPVCs represent a single virtual circuit.
The quickstart procedure in this section provides a summary of the tasks required to configure SPVCs and SPVPs on Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches. This procedure is provided as an overview and as a quick reference for those who have previously configured these types of connections.
Step 1
See the " "ATM Trunk Configuration Quickstart" section.
Configure the trunks that link the switches through which the ATM end stations connect. Be sure to add the PNNI controller on each switch and select that controller when partitioning trunks.
Step 2
dsppnni-reachable-addr network
At the PXM, verify connectivity between the node pairs that will host SVCs.
See the " Verifying End-to-End PNNI Communications" section in Chapter 6, "Card Management on MPSM-T3E3-155 and MPSM-16-T1E1."
Step 3
Configure UNI ports for the ATM end stations at each end of the SVC, and assign either static or dynamic addressing to each line. Be sure to add the PNNI controller on each switch and select that controller when you partition trunks.
Step 4

PNNI Virtual Trunk Configuration Quickstart
Virtual trunks are introduced and explained in the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2. Figure 3-1 illustrates how to configure a virtual trunk.
The Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches support:
•
•
Figure 3-1 shows a network topology that has two virtual trunks. At Private Switch A, both virtual trunks use the same line to connect to the core ATM network. Within the core ATM network, soft virtual permanent paths (SPVPs) provide direct communication paths between the core edge switches. Private Switch A has virtual trunks to Private Switches B and C and communicates with them as though they were directly connected.

Cisco BPX PNNI Trunk Configuration Quickstart
When the Cisco SES PNNI controller is attached to a Cisco BPX switch, the Cisco BPX switch can participate in a PNNI network with Cisco MGX 8850 (PXM1E/PXM45) or Cisco MGX 8830 switches. The connection between a Cisco MGX 8850 (PXM1E/PXM45) or Cisco MGX 8830 switch and a Cisco BPX switch is a trunk between an MPSM card in the Cisco MGX switch and a Cisco BXM card in the Cisco BPX switch. For instructions on configuring the BXM end of the trunk, refer to the Cisco SES product documentation. This section describes how to configure the MPSM end of the trunk.
The procedure for configuring the MPSM end of the trunk is similar to the general procedure for configuring MPSM trunks. The following procedure is customized for setting up Cisco BPX PNNI trunks.

Most of the descriptions and procedures in this section use ATM service context commands. See Chapter 7, "Command Reference" for detailed descriptions of the MPSM-T3E3-155 and MPSM-16-T1E1 ATM service commands and parameters. Some of the procedures in this section use PXM commands and PNNI commands. Refer to the Cisco MGX 8800/8900 Series Command Reference, Release 5.2 for descriptions of the PXM and PNNI commands and parameters.

Adding ATM Ports
On an MPSM-T3E3-155 or MPSM-16-T1E1 card, a logical port is also called a virtual interface and is represented by the ifNum variable. The MPSM cards can have the following types of interfaces:

Bringing up a line establishes minimal connectivity between two nodes. When you add an ATM port to a line or path, you enable ATM communication over the line.
Each line can support UNI, NNI, VNNI, EVNNI, or EVUNI ports. UNI ports are used for lines that connect to PBXs, ATM routers, and other ATM devices that connect to the core ATM network through the switch. NNI ports are used for trunks that connect to other core ATM network devices, such as another MGX 8850 switch. VNNI ports support virtual trunk connections between two ATM end stations. EVNNI and EVUNI are enhanced virtual trunks for network and user connections.
You must configure one ATM port for each line or path to enable ATM communication over that link.
When you add the ATM port to the line or path, you define the port type (UNI, VUNI, NNI, VNNI, EVNNI, or EVUNI).
Note
To add an ATM port to a path or line, use the following procedure.
Step 1
Step 2
To display a list of the lines and their numbers, enter the dsplns command:
MGX8850.10.MPSM-155[ATM].a > dsplns.If you adding a port to a path, enter the dsppaths -all command to display a list of all paths:
MGX8850.10.MPSM-155[ATM].a > dsppaths -allStep 3

The interfaces listed can include UNI, NNI, VNNI, EVNNI, and EVUNI ports. When you add a port, you must specify a port number that is unique on the card. For example, if port number 2 is assigned to line 1.1 (bay 1, line 1), you cannot use port 2 on any other line on that MPSM-T3E3-155 card.
