Provisioning PXM1E Communication Links
This chapter describes how to add logical ports and virtual connections to physical lines. This chapter explains how to provision the link and connection types listed in Table 11-1.
Table 11-1 PXM1E Link and Connection Types
PXM1E Link or Connection Type
|
Description
|
PNNI trunks
|
PNNI trunks connect MGX switches to other MGX switches.
|
PNNI UNI ports
|
PNNI UNI ports connect MGX switches to CPE.
|
SVCs1
|
SVCs are temporary connections that are brought up and torn down upon request from CPE.
|
SPVCs2
|
SPVCs are permanent connections that can be rerouted if a link fails.
|
PNNI virtual trunks
|
PNNI virtual trunks are used to traverse public networks. The virtual trunk endpoints are on separate networks, but the path between the networks is treated like a single link.
|
Cisco MGX 8850 (PXM1) feeder PNNI trunks
|
Feeder trunks link a feeder switch, such as a Cisco MGX 8230 or Cisco MGX 8250 switch, to a Cisco MGX 8850 Release 4 switch. The feeder switch concatenates relatively low speed traffic and feeds it over a higher speed interface to the Cisco MGX 8850 switch, which provide the link to the ATM network core.
|
BPX PNNI trunks
|
BPX PNNI trunks provide PNNI links between MGX 8850 witches and BPX switches that support PNNI. The BPX switch supports PNNI when connected to the Cisco SES PNNI Controller.
|
AINI3 links
|
AINI links enable connectivity between two independent PNNI networks and block the PNNI database exchange so the two networks remain independent.
|
IISP4 links
|
IISP links enable connectivity between two independent PNNI networks and block the PNNI database exchange so the two networks remain independent. IISP is the predecessor to AINI and should be used only when AINI is not supported on either end of the link.
|
XLMI5 links
|
XLMI links connect PNNI networks to AutoRoute networks. XLMI links enable the expansion of AutoRoute networks using PNNI, and they facilitate migration from AutoRoute networking to PNNI.
|
The configuration differences between these types of connections are often as simple as an additional command or a different set of command options. To eliminate redundancy and help experienced users complete configuration procedures quickly, this chapter uses configuration quickstarts and task descriptions to explain how to configure connections.
The first time you configure a connection type, use the quickstart procedure to see the order of tasks to complete, and then read the task descriptions for detailed instructions.
Note
For all commands in this chapter, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Command Reference for detailed information.
Note
Before you start configuring ATM connections, complete the general switch configuration as described in Chapter 3, "Configuring General Switch Features." Some of the procedures described in this chapter will not work if the switch has not been set up properly.
Quickstart Provisioning Procedures
The following sections present abbreviated procedures that you can use to provision connections.
ATM Trunk Configuration Quickstart
ATM trunks connect the switch to other ATM switches in the core ATM network. The quickstart procedure in this section provides a summary of the tasks required to configure ATM trunks on Cisco MGX switches. This procedure is a quick reference for those who have previously configured these types of connections.
Note
The trunk configuration is not complete until the following procedure has been completed on the switches at both ends of the trunk.

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 communications 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 switches. This procedure is provided as an overview and as a quick reference for those who have previously configured UNI ports.
Note
The link configuration is not complete until the equipment at both ends of the line has been configured with compatible configuration settings.

See the "Configuring ILMI on a Port" section later in this chapter.
|
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) 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 communications. With the exception of CPE configuration, all these tasks are described in this chapter.
Note
The tasks in the following procedure do not have to be completed in the order presented. However, all tasks must be completed before SVCs will operate.
| |
Command
|
Purpose
|
Step 1
|
See the "ATM Trunk Configuration Quickstart" section earlier in this chapter.
|
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
|
Verify connectivity between the node pairs that will host SVCs.
See the "Verifying End-to-End PNNI Communications" section later in this chapter.
|
Step 3
|
See the "PNNI UNI Port Configuration Quickstart" section earlier in this chapter.
|
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 communications 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.
See the "Displaying SVCs" section in Chapter 13, "Switch Operating Procedures."
|
It is beyond the scope of this guide to describe how to configure each model of the CPE to communicate with the switch. To complete this configuration, you will need to learn the capabilities of the CPE and the switch and define a set of communications parameters that are supported by both devices. For example, the Cisco MGX switches support UNI 3.1 communications, but if the CPE does not, you must select a signaling protocol (such as UNI 3.0) that is supported by both devices.
Once all the requirements have been met for SVC connections, CPE devices can establish SVC connections to other CPE devices on the same switched network.
SPVC and SPVP Configuration Quickstart
A soft permanent virtual circuit (SPVC) is a permanent virtual circuit (PVC) that can be rerouted using the Private Network-to-Network Interface (PNNI) Version 1.0 protocol. As with PVCs, SPVCs are full-time connections. A PVC, however, uses a predefined circuit path and will fail if the path is interrupted. Using the PNNI protocol, SPVCs can be rerouted to avoid failed communication links or to use links that offer better bandwidth.
An SPVP is a permanent virtual path that can be rerouted using the PNNI Version 1.0 protocol. The difference between an SPVC and an SPVP is that the SPVP supports multiple virtual circuits, whereas a SPVC is by definition a single virtual circuit. As with SPVCs, when an SPVP fails, PNNI can determine if an alternate route exists and reroute the connection.
The quickstart procedure in this section provides a summary of the tasks required to configure SPVCs and SPVPs on Cisco MGX 8850 (PXM1E) 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.
PNNI Virtual Trunk Configuration Quickstart
Virtual trunks are introduced in the "Multiservice Edge Aggregation" section in "Preparing for Configuration." Figure 11-1 shows illustrates how a virtual trunk is configured.
Figure 11-1 Virtual Trunk Topology
Figure 11-1 shows an example of configuration data that you can use when following the quickstart procedure below. Note that the single trunk between Private Switch A and Edge Switch A hosts two virtual trunks, which terminate at Virtual Network-to-Network Interface (VNNI) ports 10:1.2:2 and 10:1.2:7. The switch supports up to 256 VNNI ports on a UNI link and up to 4096 VNNI ports on an NNI link.
To set up a virtual trunk, the following tasks have to be completed:
•
Virtual trunks must be defined between the private network nodes and the core edge nodes.
•
The core network operators must define an SPVP for each virtual trunk that connects the core edge nodes on the virtual trunk path.
The Cisco MGX switches support:
•
Up to 256 SPVPs across an ATM core network (or ATM cloud). The range is from 0 to 255.
•
Up to 60 virtual trunks on a physical interface with a total of 60 per PXM1E card and 100 ports per switch.
•
Virtual trunks can support SPVPs, provided a range of VPIs is configured in the virtual trunk's partition.
The following quickstart procedure provides a summary of the tasks required to configure virtual trunks on Cisco MGX switches. This procedure is provided as an overview and as a quick reference for those who have previously configured these types of connections.

BPX PNNI Trunk Configuration Quickstart
When the Cisco SES PNNI controller is attached to a Cisco BPX switch, the BPX switch can participate in a PNNI network with Cisco MGX switches. The connection between an Cisco MGX 8850 (PXM1E) switch and a BPX switch is a trunk between an PXM1E card in the MGX switch and a BXM card in the BPX. For instructions on configuring the BXM end of the trunk, refer to the Cisco SES product documentation. This section describes how to configure the PXM1E end of the trunk.
The procedure for configuring the PXM1E end of the trunk is similar to the general procedure for configuring PXM1E trunks. The following quickstart procedure is customized for setting up BPX PNNI trunks.
Note
The trunk configuration is not complete until the BXM end of the trunk is configured.
Caution 
You need to allocate PNNI resources before you can configure a BPX PNNI trunk. To verify that the PNNI resource has been allocated on the trunk, enter the
dsprsrc <
slot.port> command.

XLMI Link Configuration Quickstart
An Extended Link Management Interface (XLMI) link joins a PNNI network with an AutoRoute network. After you establish an XLMI link, you can configure connections that link CPE in the PNNI network with CPE in the AutoRoute network. The interconnection of PNNI and AutoRoute networks enables network expansion beyond the limits of AutoRoute and facilitates a gradual migration from an all AutoRoute network to an all PNNI network.
To establish an XLMI link, you need to the following tasks:
1.
Configure a PXM1E port for the XLMI link.
2.
Configure a BXM port for the XLMI link.
3.
Create a connection between a destination on the PNNI network and a destination on the AutoRoute network.
The quickstart procedure in this section describes how to configure an PXM1E port to support an XLMI link, and references the instructions for creating a connection between the PNNI and AutoRoute networks. Before you begin configuration, consider the following guidelines and limitations:
•
XLMI cannot be provisioned on a port which already has connections provisioned. To change the port to XLMI, you must first delete all existing connections.
•
The control VC for LMI uses VPI = 3 and VCI = 31. These numbers are not allowed on other types of connections.
•
Each PXM1E card supports a maximum of 16 links to AutoRoute networks and feeder nodes.
•
Each PXM1E port can support one link to an AutoRoute network, so the maximum number of links to AutoRoute networks is equal to the maximum number of physical PXM1E ports.
•
XLMI links support SPVCs and SPVPs. SVCs and LVCs are not supported.
•
XLMI is not supported on virtual trunks.
•
The various XLMI timers are not configurable on the PXM1E. Timer configuration is done on the BPX. The values for the LMI timers on PXM1E are
–
LMI SPVC Status Enquiry Timer (T393): 10 sec
–
LMI SPVC Update Status Timer (T394): 10 sec
–
LMI Retry Timers (N394 and N395): 5 sec

General PXM1E Configuration Procedures
This section describes the following general procedures for configuring PXM1E card communications:
•
Adding ATM Ports
•
Partitioning Port Resources Between Controllers
•
Selecting the Port Signaling Protocol
•
Assigning Static ATM Addresses to Destination Ports
•
Configuring ILMI on a Port
Adding ATM Ports
The previous chapter described how to bring up physical lines by specifying the correct line port number. The line ports correspond to line connectors on the switch back cards. Bringing up a line establishes minimal connectivity between two nodes. When you add an ATM port to a line, you enable ATM communications over the line.
Each line can support UNI or NNI 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 Cisco MGX 8850 (PXM1E/PXM45) switch.
You must configure one ATM port for each line or trunk to enable ATM communications over that link. You define the port type when you add the ATM port to the line or trunk. The port type can be one of the following:
•
UNI
•
NNI
•
VUNI
•
VNNI
•
EVUNI
•
EVNNI
To add an ATM port to a line, use the following procedure.
Step 1
Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2
Get the line number on which you will add the port. To display a list of the lines and line numbers, enter the following command:
mgx8830a.1.PXM.a > dsplns
Tip
Remember that you cannot configure a line until you have brought it up as described in "Bringing Up Lines," in Chapter 4, "Preparing PXM1E Lines for Communication."
Step 3
Verify that the line and port number you want to use is not configured. To display a list of the ports configured on the PXM1E card, enter the following command:
mgx8830a.1.PXM.a > dspports
This command displays all ports on the PXM1E card in the ifNum (interface number) column. The interfaces listed include UNI, NNI, VUNI, VNNI, EVUNI, and EVNNI ports. Pay attention to the port numbers already in use. When you add a port, you must specify a port number that is unique on the PXM1E card. For example, if port number 2 is assigned to line 2.1 (bay 2, line 1), you cannot use port 2 on any other line on that PXM1E card.
Step 4
To add an ATM port to a line, enter the following command:
mgx8830a.1.PXM.a > addport <ifNum> <bay.line> <guaranteedRate> <maxRate> <sctID> <ifType>
[vpi <vpi>] [-minvpi <minvpi>] [-maxvpi <maxvpi>]
Table 11-2 lists the parameter descriptions for adding ports. Figure 11-2 shows the relationship between logical interface numbers and physical lines.
Table 11-2 Parameters for addport Command
Parameter
|
Description
|
ifNum
|
An ATM port is also called an interface. An ATM port is defined by its slot, bay, line, and interface numbers. You do not have to enter a slot number during port configuration because you identify the slot number when you select the card.
Enter a number from 1 to 31 to identify this interface. For UNI and NNI ports, you can assign one logical interface per line.
|
bay
|
Replace <bay> with 2 to indicate the lower bay.
|
line
|
Replace <line> with the number that corresponds to the back card port to which the line is connected.
|
guaranteedRate
|
Enter the minimum rate for the port in cells per second (cps).
Note The <guaranteedRate> value should equal the <maxRate> value.
The rate ranges for PXM1E are as follows:
OC3: 50 - 353207.
T3: 50 - 96000 (PLCP) or 104268 (ADM).
E3: 50 - 80000.
T1: 50-3622 cps
E1: 50-4528 cps
|
maxRate
|
Enter the maximum rate for the port in cps.
Note The <maxRate> value should equal the <guaranteedRate> value.
The rate ranges are as follows:
OC3: 50 - 353207.
T3: 50 - 96000 (PLCP) or 104268 (ADM).
E3: 50 - 80000.
