Use this chapter to find out about the tasks typically performed to bring up the SES PNNI node. This chapter assumes the following:

•You have completed and verified the hardware installation at the BPX and the SES PNNI Controller, as described in Chapter 5 of the Cisco SES Hardware Installation Guide.

•You have completed the tasks described in Chapter 8, "SES PNNI Controller Interface Connections and Initial Configuration."

After completing the installation and initial configuration tasks, you are ready to bring up the system, using the task sequence shown in Figure 9-1.

Figure 9-1

Bringup Tasks for PNNI Controller

This chapter refers to commands that run from the BPX CLI, the SES CLI or CiscoView menus. The BPX CLI commands are documented in detail in the Cisco WAN Switching Command Reference, Release 9.3. The CiscoView menus are described in Chapter 11, "Network Management."

UNI Configuration

Use this section to find out how to use auto-configuration on the PNNI Controller, to set default PNNI values and ILMI address registration on UNI ports.

---

Note Auto configuration is enabled only if the attached ATM CPE supports ILMI. If the attached ATM CPE does not support ILMI, you must bring up the port by using the guidelines provided in the section Configuring a Port Without AutoConfiguration and Without ILMI.

---

Auto-configuration is comprised of AutoConfigure a UNI Port

AutoConfigure a UNI Port

Use the following procedure to connect an ATM UNI for auto-configuration using ILMI address registration and the VSI protocol.

At the BPX CLI, perform the following steps:

---

Step 1 Connect the appropriate cable between the BPX BXM port and the ATM CPE.

Make sure the ATM CPE is configured for ILMI.

Step 2 Use the upln command at the BPX CLI to up the line, the physical layer.

upln slot.port

Step 3 Use addport command to add port.

addport slot.port

Step 4 Use the upport command to up the port.

upport slot.port

Step 5 Use the cnfvsiif command at the BPX to configure Service Class Template for the interface. 1 is for MPLS, service template 2 is for ATMF service template on port, and 3 is for ATMF service template on trunk. For PNNI SES UNI interface, the service class template should be set to 2. Detail of service class template is found in Appendix C.

cnfvsiif slot.port 2

Step 6 Use the cnfrsrc command to set resources on the port.

A system response similar to the following example occurs:

Step 7 Use the cnfport command to enable ILMI protocol to run on the BXM card and enable VSI ILMI to PNNI controller.

example for ILMI port configuration on a BXM card:

cnfport 10.4 353208 N H I 0 16 Y Y N 30 3 4 N N 0 N Y N

-------------------------------------------------------------------------

----------------------------------------------------------------------------------

The BXM sends a VSI trap to the SES PNNI controller. When the SES PNNI controller receives the trap, it sends a VSI passthrough back to the BXM enabling auto-configuration. The information in the passthrough includes auto-configuration default parameters. Auto-configuration parameters include details such as autoconfiguration on, service registry on, address registration on, node prefix, and others.

The BXM starts the ILMI protocol with the attached ATM CPE. The BXM then send the SES PNNI controller the following port information: vpi/vci range, interface type, device type, ILMI version, and UNI Signaling version.

The PNNI Controller then starts the UNI signaling stacks.

---

---

Note All ILMI features on SES PNNI are default to be on. You do not need to use cnfaddrreg, cnfautocnf to enable ILMI features on SES PNNI.

---

Modifying Port Parameters After AutoConfiguration

To modify port parameters after AutoConfiguration, perform the following steps at the SES PNNI Controller CLI:

---

Note When using service-affecting parameters on a port already configured, the port must be must be brought down prior to attempting modifications to port parameters.

---

Use the following procedure to modify port parameters.

---

Step 1 Use the dnpnport command—either from CiscoView or the PNNI Controller CLI—to down the port.

This brings down the signaling stacks for the port.

Step 2 Change the appropriate parameter with one of the following cnf commands:

•cnfpnportsig

•cnfpnportrange

•cnfilmienable

•cnfaddrreg 

•cnfautocnf

Non-service affecting parameters can be changed without downing the port. For example, you do not need to down the port to execute the following SES CLI commands:

•cnfpnportcc

•cnfpnportcac

•addprfx

•addaddr

Step 3 Use one of the following display commands to see the current configurations:

•dsppnportsig

•dsppnportrange

•dsppnilmi

•dsppnportcc

•dsppnportcac

•dspprfx

•dspaddr

Step 4 Use the uppnport command to enable the port.

---

Preconfiguring a UNI Port with AutoConfiguration

Use the following procedure to preconfigure specific parameters before a port is brought up with AutoConfiguration.

Use the SES PNNI Controller CLI to perform steps 1 through 3.

---

Step 1 Use the addpnport command at the PNNI Controller CLI to define an UNI port.

---

Note Ports are administratively down, by default.

---

Step 2 Modify the appropriate parameter with one of the following PNNI Controller cnf commands:

•cnfpnportsig

•cnfpnportrange

•cnfilmienable

•cnfaddrreg

•cnfautocnf

Step 3 Use the uppnport command to up the PNNI port.

---

Note The signaling stacks are not yet brought up because the port configuration has not yet been received from the BXM.

---

Use the BPX CLI to perform steps 4 through 8.

Step 4 Use the upln command at the BPX CLI to bring up the line.

Step 5 Use the addport command to add port.

Step 6 Use the upport command to bring up the port.

Step 7 Use the cnfvsiif command at the BPX CLI to configure PNNI service template, 2.

Step 8 Use the cnfrsrc command to set resources on the port.

Step 9 Use the cnfport command to enable ILMI protocol on BXM port.

The following results occur:

a. The BXM now sends a VSI trap to the SES PNNI controller.

b. The PNNI Controller starts the UNI signaling stacks:

•If AutoConfiguration is enabled, the SES PNNI controller will send a VSI passthrough to the BXM. The BXM initiates ILMI with the ATM CPE. The BXM then sends VSI passthrough back to the SES PNNI controller with port information, at which time the SES PNNI controller starts the UNI signaling stacks.

•If AutoConfiguration is disabled, the SES PNNI controller will start the UNI signaling stacks for the port.

---

Configuring a Port Without AutoConfiguration and Without ILMI

If the attached ATM CPE does not support ILMI, you must bring up the port without auto-configuration.

Use the BPX CLI to perform steps 1 through 4.

---

Step 1 Use the upln command at the BPX CLI to up the line.

Step 2 Use the addport command to add the port.

Step 3 Use the upport command to up the port.

Step 4 Use the cnfvsiif command at the BPX CLI to configure PNNI service template, 2.

Step 5 Use the cnfrsrc command to set resources on the port.

The following results occur:

a. The BXM now sends a VSI trap to the SES PNNI controller.

b. The SES PNNI controller receives the BXM port configuration through VSI with ILMI disabled. The SES PNNI controller brings up the UNI or PNNI signaling stacks.

Use the SES PNNI Controller CLI to perform step 5.

Step 6 Use the addaddr command at the PNNI Controller to set ATM addresses for the port. This step is necessary because there is no automatic address registration from ILMI.

---

---

Note An address can only be provisioned on a UNI if ILMI address registration is disabled.

---

NNI Trunk Configuration

Use this section to find out how to configure a PNNI trunk on BPX and SES PNNI Controller.

AutoConfigure an NNI Trunk

Use the following procedure to connect an ATM NNI trunk with auto-configuration using ILMI and the VSI protocol.

At the BPX CLI, perform the following steps:

---

Step 1 Connect the appropriate cable between the BPX BXM ports.

Make sure the other BPX BXM port is configured for ILMI.

Step 2 Use the uptrk command at the BPX CLI to up the trunk.

uptrk slot.port

Step 3 Use the addtrk command at the BPX CLI to add AutoRoute on the trunk.

addtrk slot.port

Since AutoRoute is needed to provide IP connectivity, Time of Date, and Network Clocking for this release of BPX/SES, it is essential to add AutoRoute partition in a trunk even if there is no "AutoRoute" PVC service to be implemented. Limit resource is needed to be provisioned to carry IP connectivity, Time of Date, and Network Clocking. Notice that when the AutoRoute service is added to the trunk, the VPI = 0 and 1 will be reserved for AutoRoute. The available VPI for VSI (or PNNI) will start from
VPI = 2.

Step 4 Use the cnfvsiif command at the BPX to configure Service Class Template for the interface. 1 is for MPLS, service template 2 is for ATMF service template on port, and 3 is for ATMF service template on trunk. For PNNI SES NNI trunk, the service class template should be set to 3. Detail of service class template can be found in Appendix C.

cnfvsiif slot.port 3

Step 5 Use the cnfrsrc command to set resources on the port.

A system response similar to the following example occurs:

----------------------------------------------------------------------------

Step 7 Use the cnfvsipart command to enable VSI ILMI.

cnfvsipart slot.port partition_id Enable_ilmi [y/n]

Example:

----------------------------------------------------------------------------

oriobpx3 TN StrataCom BPX 8620 9.2.3U Feb. 17 2000 08:25 PST

Last Command: cnfvsipart 1.2 1 y

-------------------------------------------------------------------------------

The BXM now sends a VSI trap to the SES PNNI controller.

When the SES PNNI controller receives the trap, it sends a VSI passthrough back to the BXM to enable auto-configuration. The information in the passthrough includes auto-configuration default parameters.

The BXM then starts the ILMI protocol with the attached BXM port. The BXM will then send the SES PNNI controller the port information: vpi/vci range, interface type, device type, ILMI version, and NNI Signaling version.

Finally, the PNNI Controller starts the PNNI signaling stacks.

Note that all ILMI features on SES PNNI are default to be on, there is NO need to use cnfautocnf to enable ILMI features on SES PNNI.

Step 8 Use the dspvsipartcnf command to view VSI ILMI functionality status (whether enabled or not) for various VSI partitions on the interface.

Example:

----------------------------------------------------------------------------

Preconfiguring a NNI Trunk with AutoConfiguration

Use the following procedure to preconfigure specific parameters before a trunk is brought up with AutoConfiguration.

Use the SES PNNI Controller CLI to perform steps 1 through 3.

---

Step 1 Use the addpnport command at the PNNI Controller CLI to define a PNNI port.

---

Note Ports are administratively down, by default.

---

Step 2 Modify the appropriate parameter with one of the following PNNI Controller cnf commands:

•cnfpnportrange

•cnfaddrreg

•cnfautocnf

---

Note The modified parameters will be used by autoconfiguration to negotiate a common parameters with its peer ILMI IME(Interface Management Entity).

---

Step 3 Use the uppnport command to up the PNNI port.

---

Note The signaling stacks are not yet brought up because the port configuration has not yet been received from the BXM.

---

Use the BPX CLI to perform steps 4 through 8.

Step 4 Use the uptrk command at the BPX CLI to bring up the trunk.

Step 5 Use the addtrk command at the BPX CLI to add AutoRoute.

Step 6 Use the cnfvsiif command at the BPX CLI to configure PNNI service template, 3.

Step 7 Use the cnfrsrc command to set resources on the port.

Step 8 Use the cnftrk command to enable ILMI protocol on BXM port.

Step 9 Use the cnfvsipart command to bring up the port.

The following results occur:

a. The BXM now sends a VSI trap to the SES PNNI controller.

b. The PNNI Controller starts the PNNI signaling stacks:

•If AutoConfiguration is enabled, the SES PNNI controller will send a VSI passthrough to the BXM. The BXM initiates ILMI with the ATM CPE. The BXM then sends VSI passthrough back to the SES PNNI controller with port information, at which time the SES PNNI controller starts the PNNI signaling stacks.

•If AutoConfiguration is disabled, the SES PNNI controller will start the NNI signaling stacks for the port.

---

Configuring Virtual Trunk on a BXM Port

Use the BPX CLI to configure VSI on BXM ports or trunks. For more information about the VSI protocol, see "Virtual Switch Interface."

A default Service Class Template is assigned to a logical interface when the interface is upped using the upport and uptrk commands.

For example:

•uptrk 1.1

•uptrk 1.1.1 (virtual trunk, 1 -- 31)

•upport 1.1

In the above example, the default template has the identifier of 1. You can change the default Service Class Template—from Service Class Template 1—to another Service Class Template by using the cnfvsiif command. Use the dspvsiif command to view a template associated with a specified interface.

For example:

•cnfvsiif 1.1 2

•cnfvsiif 1.1.1 2

•dspvsiif 1.1

•dspvsiif 1.1.1

The cnfvsiif command assigns a selected Service Class Template to an interface (VI) by specifying the template number.:

cnfvsiif <slot.port.vtrk> <tmplt_id>

The dspvsiif command presents the type of Service Class Template assigned to an interface (VI)

dspvsiif <slot.port.vtrk>

Configure the BXM Qbin

The default Service Class Template is assigned to the interface (VI) when an interface (VI) is activated by the uptrk or upport commands. The corresponding Qbin template is then copied into the data structure of that interface at the BXM.

You can change some of the Qbin parameters by using the cnfqbin command. The Qbin is now "user configured" as opposed to "template configured." This information may be viewed on the dspqbin screen.

Qbin dependencies

The available Qbin parameters are shown in Table 9-1.

Qbins available for VSI are restricted to Qbins 10-15 for that interface.

All 32 possible virtual interfaces are provided with 16 Qbins.

Table 9-1 Service Class Template Qbin Parameters 

Template Object Name	Template Units	Template Range/Values
QBIN Number	enumeration	0 -15 (10-15 valid for VSI)
Max QBIN Threshold	u sec	1-2000000

Setting Up SVCs

After setting up the UNI ports, NNI trunks, and PNNI, you are ready to setup SVC and SPVC in a network. This section will explain how to set up an SVC. A two-node network is used to describe the SVC set up procedure.

Figure 9-3 SVC Set Up Example

SVC without ILMI Address Registration

Assuming CPE #1 has ATM address:47.00918100000000d058ac26b6.000000010800.00

Assuming CPE #2 has ATM address:47.00918100000000107bc154b5.000000010300.00

Using the following procedures to set up addresses on orioses1 and orioses3 before place the SVC call.

---

Step 1 Add CPE #1 ATM address on orioses3 UNI port 1.3:

orioses3.1.1.PXM.a > addaddr 1.3 47.00918100000000d058ac26b6.000000010800.00 160

Add ATM summary address on orioses3:

orioses3.1.1.PXM.a > addpnni-summary-addr 1 47.00918100000000d058ac26b6 104

Step 2 Add CPE #2 ATM address on orioses1 UNI port 1.8:

orioses1.1.1.PXM.a > addaddr 1.8 47.00918100000000107bc154b5.000000010300.00 160

Add ATM summary address on orioses1:

orioses1.1.1.PXM.a > addpnni-summary-addr 1 47.00918100000000107bc154b5 104

Step 3 Use dsppnni-reachable-addr network to see the summary address of the other node.

Step 4 Place a SVC call from CPE #1 to CPE #2

Use dsppncons to display SVC connection between two nodes.

------------------------------------------------------------------------------

orioses3.1.1.PXM.a > dsppncons

SVC with ILMI Address Registration

Use the following procedures to setup SVC with ILMI address registration:

---

Step 1 Configure orioses3 UNI 1.3 with ILMI enabled (cnfport)

Configure orioses1 UNI 1.8 with ILMI enabled (cnfport)

Make sure both CPE#1 and CPE#2 have ILMI turned on.

Step 2 Add Address Prefix on orioses3 and orioses1

orioses3.1.1.PXM.a > addprfx 1.3 47.00918100000000d058ac26b6 

orioses1.1.1.PXM.a > addprfx 1.8 47.00918100000000107bc154b5

Step 3 Use dsppnni-reachable-addr local to see the registered address

Step 4 Place an SVC call from CPE #1 to CPE #2 with ATM address:

47.00918100000000d058ac26b6.00d058ac4021.00

where 00d058ac4021 is the MAC addr of CPE#2

---

Configuring ATM SPVC

There are two ways to provision an SPVC: using CLI on PNNI Controller or using CWM. Using CWM to provision an SPVC will be documented in Network Management Chapter. This section will use a step-by-step example to illustrate how to use the PNNI Controller CLI to provision an SPVC.

Configuring Node Prefix

Before setting up SPVCs, the SPVC Node Prefix orthe Nodal SPVC prefix must be configured. If it is not, use the following procedures to configure it.

---

Step 1 Use the "dspspvcprfx" command to dusplay the SPVC Node Prefix:

pswpop4.1.1.PXM.a > dspspvcprfx

SPVC Node Prefix: 47.00918100000000107bc15339

Step 2 Use cnfspvcprfx com command to configure the Nodal SPVC Prefix:

pswpop4.1.1.PXM.a > cnfspvcprfx -prfx 4700918100000000c043002ddf

Step 3 pswpop4.1.1.PXM.a > dspspvcprfx

SPVC Node Prefix: 47.00918100000000c043002ddf

---

You can only configure an SPVC prefix when there is no connection on the node. The SPVC prefix must be unique across the network.

Add an SPVC Connection

Figure 9-4 shows an example of an SPVC Setup.

Figure 9-4

SPVC Setup Example

Use the following procedure to add an SPVC in a PNNI network (Use Figure 9-4 as a reference).

---

Step 1 Use the addcon command to add an SPVC Slave EndPoint.

pswpop9.1.PXM.a > addcon 9.8 111 111 1 2

LOCAL ADDR: 4700918100000000C043002DDF00000009080000.111.111

The LOCAL ADDR is the slave endpoint ATM address to be used at the master endpoint to setup an SPVC to the slave endpoint.

---

Note Service_type is selected to be 1 i.e. CBR service. The mastership is 2=slave.

---

Step 2 Use "dspcon" to show the slave endpoint configuration.

pswpop9.1.PXM.a > dspcon 9.8 111 111

Step 3 Use the addcon command to add an SPVC Master EndPoint.

svcswp20.1.PXM.a > addcon 5.3 111 111 1 1 4700918100000000C043002DDF00000009080000.111.111

When the master endpoint is added, the SPVC Manager on the SES controller will use the slave endpoint ATM address to setup an SPVC towards the slave endpoint. The mastership is 1 = master.

The following example shows the master endpoint after the master SPVC is added.

In this example, the SPVP is looped back on the same port. An SPVP connection can not be added if a VCC connection exists with same VPI.

Configuring SPVC Feeder Connection

Use the following configuration to setup SPVC feeder connection on an SES:

---

Step 1 Configure the feeder node feeder trunk with Service Class Template (SCT) 3. This is required to disable the policing for SPVC connections terminated on the feeder trunk.

svcbpx12 TN Cisco BPX 8620 9.3.1d Sep. 25 2000 14:36 PST

Trunk: 5.1

Service Class Template ID: 2

VSI Partitions :

channels bw vpi

Part E/D min max min max start end ilmi

1 E 1000 6000 10000 328207 4 4095 D

2 D 0 0 0 0 0 0 D

3 D 0 0 0 0 0 0 D

This Command: cnfvsiif 5.1 3

Interface has active VSI partition(s): changing SCT will be service affecting

3 D 0 0 0 0 0 0 D

Last Command: cnfvsiif 5.1 3

Step 2 Configure the feeder node feeder trunk with LMI/Annex G enabled. This is required for BXM to perform AIS/Abit conversion for both AutoRoute PVC and PNNI SPVC connections terminated on the feeder trunk.

Step 3 Disable OAM segment endpoint on the feeder trunk. This is required for tstdelay to work correctly. For example, Program the SPVC end point as no SEGMENT end point so that OAM cells are not terminated for connections terminating on feeder trunk.

Use cnfoamsegep to disable OAM segment for the interface. This command is issued on SES controller.

Example:

orioses1.1.PXM.a > dspoamsegep 5.3

Port OAM End Point

5.3 Yes

orioses1.1.PXM.a > cnfoamsegep 5.3 no

orioses1.1.PXM.a > dspoamsegep 5.3

Port OAM End Point

5.3 No

Step 4 Setting up PVC segment on feeder nodes

Step 5 Setting up SPVC segment in PNNI network. Make sure the vpi/vci used for SPVC segment matches the vpi/vci used by the PVC segment configured on the same feeder trunk.

Configuring Dynamic/Soft Partitioning

Dynamic/Soft Partitioing is configured on BPX. Refer to Switch Software configuration for detail.

The cnfrsrc command on the BPX is used to alter resources (for example, LCNs, BW, VPI/VCI range) allocated to a VSI partition. If ILMI has been enabled on the interface on which VPI/VCI range is being altered, then ILMI experiences a "Loss of Connectivity" as a result of the change in VPI/VCI range.

Depending on how ILMI protocol has been configured on this interface, existing connections on the can be dropped or retained. Use the dsppnilmi command to see current configuration. Configuration can be changed using the cnfilmiproto command .

If you do not want connections on the interface to be dropped when the VPI/VCI range is changed, the ILMI protocol can be configured in following manner:

cnfilmiproto port_id -securelink no -attachmentpoint no

Configuring SPVC Stats Collection

Use the following configuration to enable SPVC stats collection on an SES:

---

Step 1 Check SNMP configuration:

Check the SNMP configuration both on BCC and PXM e.g: community strings and Network IP addresses and ATM IFIP.

Step 2 Setting stats level on BCC:

Syntax: cnfcdparm <slotId> <stat-level>

There should not be any connections on the BXM when this command is executed. The BXM must be reset for the new stats level to take effect.

Step 3 Add an SPVC connections with stats enabled

To add SPVC connections with stats enabled, the "-stats enable" option must be enabled in the addcon command. To enable stats on existing SPVCs, modify the connections with cnfcon and enable the "-stats enable" option with this command.

Step 4 Stats configuration on CWM:

a. Telnet to the PXM card and setup CWM's IP address for stats using cnfstatsmgr

In the SCM GUI (e.g. "runScmGui <host>"):

a. Clickthe node tab.

b. Navigate to a node; for example, nmsbpx14.

c. Telnet to nmsbpx14.

d. Run the following command: cnfstatmast <your scmctrlsvr host ip>

e. Enable stats by edit default parameters.

f. Add the required stat id's and start collecting.

g. Wait more than 15 minutes to see if any stats file has been collected.

Step 5 If no files are being collected after 30 minutes, check the error logs for any error messages.

For the installation of SCM GUI check the CWM configuration guide. There should bea section on the following installations:

•installation CWM.

•add user information in node_info table.

•install SCM.

•Run SCM GUI
