Chapter: Chapter 12: Managing Southbound and Northbound Interfaces

Managing Southbound and Northbound Interfaces

Cisco Prime Optical uses protocols such as CORBA, SNMP, and HTTP to provide southbound and northbound interfaces to communicate with NEs and operations support systems (OSSs).

This topic contains the following information:

How Do I Manage Southbound Interfaces?

The Prime Optical server communicates with NEs through the data communications network (DCN) by using several protocols (CORBA, SNMP, HTTP, and so on).

You can access NEs in Prime Optical through:

  • NE Explorer—Provides detailed rack, shelf, and card-level views of an NE. Detailed NE attributes and parameters are viewable and configurable.
  • Craft Interface—Depending on the NE model, Prime Optical provides access to NE craft interfaces such as CTC, Cisco Edge Craft, web browsers, and the command line interface (CLI). Table 2-4 lists the available craft interfaces by NE model.

Southbound Port Details

This section explains the ports that Prime Optical uses to communicate with NEs. For more information, see, Southbound Port Details .

Using a Static CORBA Listener Port on the Prime Optical Server

See CTC IIOP Port Configuration.

Client-Server Communication Protocols

This section explains the protocols that Prime Optical uses for client-server communication. For more information, see Client-Server Communication Protocols .

Changing the Prime Optical Server Port

Normally, users do not change the Prime Optical server port. In cases where the Prime Optical server port is used for other applications, use the NE Service pane to change the TCP port number of the Prime Optical server. All Prime Optical clients use the JMOCO port to connect to the Prime Optical server.

Step 1 In the Domain Explorer window, choose Administration > Control Panel .

Step 2 In the Control Panel window, click NE Service to open the NE Service pane. Click the NE Poller tab.

Step 3 In the Prime Optical Server Port field, change the server port. The server port in the Active column displays the current port. The server port in the After Restart column displays the port that is active after the server is restarted.

Step 4 Click Save . Changes to this parameter take effect only after the server is restarted.

 

Changing the HTTP Server Port

If other applications use the HTTP server port, you can change the default port. Complete the following steps:

Step 1 Open a shell on the Prime Optical server workstation and enter the following command to shut down the Prime Optical server:

opticalctl stop
 

Step 2 Enter the following commands to change directories to the HTTP server directory and create a copy of the configuration file:

cd /Apache/conf
cp httpd.conf httpd.conf.ori
 

Step 3 Locate the following lines in the httpd.conf file:

Listen IP-address:8051
Listen 127.0.0.1:8051
ServerName IP-address:8051
 

In each of these lines, replace the default port 8051 with the new HTTP server port.

Step 4 Enter the following command to start the Prime Optical server:

opticalctl start
 

Step 5 On each Prime Optical client, locate the following line in the
Prime Optical-client-installation-directory /config/ems_client.cfg:

Apache_port=\:8051
 

Replace 8051 with the new HTTP server port.

Caution Be sure to repeat this change on each Prime Optical client.

Step 6 Start the Prime Optical client. To verify that the HTTP services are working, choose Help > Current Window in the Domain Explorer .

 

How Do I Manage Northbound Interfaces?

Prime Optical GateWay is an architectural component that provides northbound EMS-to-NMS interface mediation. Prime Optical GateWay allows service providers to integrate Prime Optical with their OSSs by using open, standard interfaces.

Prime Optical supports three gateway modules that provide northbound EMS-to-NMS interface mediation. Not all NE types are supported by each module. Table 2-2 shows the NE types supported by each gateway module. This section contains the following information:

Managing Prime Optical GateWay/SNMP

SNMP is a network management protocol used almost exclusively in TCP/IP networks. SNMP allows you to monitor and control network devices, manage configurations, collect statistics, check performance, and monitor security.

Prime Optical’s GateWay/SNMP feature provides an SNMP trap forwarding service, where any trap generated or received by the server workstation will be forwarded to the set of defined trap destinations. Traps are autonomous notifications sent by an SNMP agent to an SNMP manager, such as HP Open View. Prime Optical GateWay/SNMP does not support southbound SNMP relaying (SNMP SET, GET, and GETNEXT).

The primary advantage of Prime Optical GateWay/SNMP is to limit the amount of traffic on the wide-area DCN. Imagine NEs deployed over a wide geographic area and a centralized network operations center where the management systems are located. If there are five OSs required to receive NE traps, instead of having each NE send five traps over the wide area to each OS, send a single trap to Prime Optical, which can then relay the trap locally in the NOC to the other OSs. NE configuration is also simpler because only one trap destination needs to be configured on each NE.

Prime Optical GateWay/SNMP supports SNMPv1, SNMPv2c, and SNMPv3 traps. SNMPv2c traps contain the Prime Optical host IP address in the source address of the IP packet.

SNMPv3 traps contain the OSS username, authentication protocol, authentication password, privacy protocol, and privacy password.

To enable the OS to determine which NE sent the trap, the trap must be defined with a variable binding that indicates the source NE.

Prime Optical GateWay/SNMP applies to any NE with an SNMP interface.

Note Table 2-2 shows the NEs that support Prime Optical GateWay/SNMP.

Figure 12-1 shows the Prime Optical GateWay/SNMP communications architecture within a service provider’s OSS environment.Prime Optical GateWay/SNMP Communications Architecture

Figure 12-1 Prime Optical Gateway/SNMP Communications Architecture

 

Starting and Stopping the Prime Optical GateWay/SNMP Service

Prime Optical GateWay/SNMP is a Prime Optical process that can be separately started and stopped through the Control Panel . NEs must be configured with the Prime Optical server IP address as a trap destination for traps to be sent from the NEs to Prime Optical.

Step 1 In the Domain Explorer window, choose Administration > Control Panel .

Step 2 In the Control Panel window, click GateWay/SNMP Service . Table 12-1 provides descriptions.

Step 3 In the Status area, click the Start button to start Prime Optical GateWay/SNMP . Notice that the service status toggles to Active .

Step 4 Click Stop to stop the service. The service status toggles to Not Active .

Note The Prime Optical GateWay/SNMP Service can take up to 60 seconds to initialize after the GUI status has changed to indicate that the service is up. The status is an indication of the successful initiation of the service startup, not successful initialization. To avoid problems with the service hanging, wait at least 60 seconds after starting or stopping the service before restarting it.

 

Adding and Removing a Prime Optical GateWay/SNMPv1 or Prime Optical GateWay/SNMPv2 Host

You can configure up to 16 SNMP trap destination hosts for Prime Optical GateWay/SNMP. Prime Optical enforces a duplication check error to ensure that you do not enter duplicate OSS IP addresses.

Step 1 In the Domain Explorer window, choose Administration > Control Panel .

Step 2 In the Control Panel window, click GateWay/SNMP Service . Table 12-1 provides descriptions.

Step 3 In the SNMP Hosts field, enter a valid IP address or hostname for the SNMP forwarding host; then, click Add . To remove an SNMP host, select the IP address or hostname of the host and click Remove .

Step 4 Repeat for each host to be added or removed; then, click Save .

Managing Prime Optical GateWay/CORBA

Note This section provides a high-level overview of Prime Optical GateWay/CORBA. For detailed information about Prime Optical GateWay/CORBA, including how to enable username and password encryption, set the heartbeat event, and create OSS clients, refer to the Cisco Prime Optical GateWay/CORBA User Guide and Programmer Manual.

The Common Object Request Broker Architecture (CORBA) is a middleware platform defined by the Object Management Group (OMG). The Prime Optical GateWay/CORBA option is a CORBA-based interface that provides higher-layer management systems with fault, inventory, performance, configuration, Layer 1 circuit provisioning, and Layer 2 VLAN management information for NEs. The Prime Optical GateWay/CORBA option is based on the TeleManagement Forum (TMF) standards for the NMS-to-EMS interface.

Because it is CORBA-based, Prime Optical GateWay/CORBA is independent of the hardware that the integrated OSS is running. This independence allows service providers to easily add Prime Optical as a building block of their management environment.

Note Table 2-2 shows the NEs that support Prime Optical GateWay/CORBA.

Figure 12-2 shows the Prime Optical GateWay/CORBA communications architecture within a service provider’s OSS environment.

Figure 12-2 Prime Optical GateWay/CORBA Communications Architecture

 

 

Prime Optical GateWay/CORBA is based on the following TMF standards:

  • TMF513 v3.0: Multi-Technology Network Management Business Agreement
  • TMF608 v3.0: Multi-Technology Network Management Information Agreement
  • TMF814 v3.0: Multi-Technology Network Management Solution Set

Configuring the CORBA Timeout

The CORBA timeout determines the number of seconds that the Prime Optical server has to process a CORBA call and return it to the Prime Optical client. If the Prime Optical server does not return a response in time, CORBA automatically times out.

Step 1 Open the ems-client.cfg file.

By default, the configuration file (ems-client.cfg) is located in the /config directory path under the Prime Optical client installation directory.

Step 2 Set the CORBA_Call_Timeout_Seconds parameter to the desired value. The default timeout is 120 seconds; the recommended range is from 120 to 300 seconds.

Note If the NE is busy or if the Prime Optical server is processing many requests, you might need to increase the CORBA timeout parameter accordingly.

Step 3 Save and close the ems-client.cfg file.

 

Starting or Stopping Prime Optical GateWay/CORBA

Step 1 In the Domain Explorer window, choose Administration > Control Panel .

Step 2 Click GateWay/CORBA Service to open the GateWay/CORBA Service pane.

Step 3 In the Global tab > Status area, click the Start button to start GateWay/CORBA or the Stop button to stop the service.

Note The Prime Optical GateWay/CORBA Service can take up to 60 seconds to initialize after the GUI status has changed to indicate that the service is up. The status is an indication of the successful initiation of the service startup, not successful initialization. To avoid problems with the service hanging, wait at least 60 seconds after starting or stopping the service before restarting it.

 

Viewing the Prime Optical GateWay/CORBA Service Pane

Use the Prime Optical GateWay/CORBA Service pane to start and stop the Prime Optical GateWay/CORBA service and configure CORBA ports and parameters. Table 12-5 provides descriptions.

Note In CTM R9.2, Prime Optical server ports can be configured from the Ports Configuration tab. Unless otherwise noted, all port configuration changes require a Prime Optical GateWay/CORBA restart.

 

Table 12-5 Field Descriptions for GateWay/CORBA Service Pane

Field
Description
Global Tab

Service Status

Displays the current status of the service: Active, Not Active, or Not Installed.

Service Action

Allows you to stop or start a process. Notice that the Service Action button toggles between Stop and Start, and the Service Status field changes accordingly. This field is not available if the Service Status is Not Installed.

Enable Encryption for Username and Password

When checked, usernames and passwords are transmitted between the EMS server and the OSS in encrypted format. The maximum encryption length is 53 bytes. If this check box is unchecked, Prime Optical GateWay/CORBA usernames and passwords are transmitted without encryption. By default, encryption is disabled at installation.

Heartbeat for Notification Channel

Notifies the OSS if a failure in the notification service has occurred. The heartbeat is measured in minutes; the range is 0 to 999 minutes. A zero value implies that the heartbeat is disabled.

Maximum Number of Simultaneous Sessions

Specifies the number of Prime Optical GateWay/CORBA sessions that can be active at the same time. The range is from 4 to 25; the default is 4.

Maximum Events per Consumer

Sets the MaxEventsPerConsumer administrative quality of service (QoS) parameter on the notification channel. The notification server uses this property to bound the maximum number of events in a given channel allowed to queue at any one time. The default value is 0, meaning that the notification server does not limit the maximum number of events that can be queued. If no limits are imposed on the queue, the notification server might run out of memory, because the server must keep all events in memory until they are consumed by all registered consumers.

Caution Any change to this value should be done with extreme caution. If you set the value too low, the NMS cannot receive all notifications. If you set the value too high, the Prime Optical notification server runs out of memory. The current value can handle alarm bursts of 10,000 events per minute.

Notification Service Name

Defines the service name used by the resolve_initial_reference function to get a reference to the notification service.

The Prime Optical GateWay/CORBA installation installs the notification service. However, if you want to use your own notification service, you can modify this parameter.

Note You do not need to modify this parameter if you plan to use the notification service that is bundled with Prime Optical GateWay/CORBA.

Notification Service Naming Context

Defines the naming context of the notification service. This property is used when the resolve_initial_reference function fails to resolve the notification service. Prime Optical GateWay/CORBA contacts the naming service to resolve the name context defined in this property. The value of this property must match the value published by your notification server.

Note You do not need to modify this parameter if you plan to use the notification service that is bundled with Prime Optical GateWay/CORBA.

Notification Service Factory IOR Filename

Enter the notification service factory Information Object Repository (IOR) filename located in the /opt/CiscoTransportManagerServer/openfusion/domains/OpenFusion/localhost/NotificationService/NotificationSingleton/NotificationService.ior directory.

The FactoryIORFile property defines the path to a text file that contains the IOR of the notification service. This property is used only after the resolve_initial_reference function and the naming service both fail. Prime Optical GateWay/CORBA opens the file as defined by the URL format in this property and retrieves the IOR. This parameter allows you to run your notification service on a different host to improve performance.

Note You do not need to modify this parameter if you plan to use the notification service that is bundled with Prime Optical GateWay/CORBA.

Name Service Server List

Defines where the name servers are running. Accepts a comma-separated list of hostnames.

Name Service Root IOR

Defines the path to find the naming service’s IOR on each host defined on the server list. The complete path is constructed as <http://<item>_of_ServerList><RootIORLoc>.

Error Level

Defines the error level of messages to log. Error levels are:

  • Critical
  • Major
  • Minor
  • Informational
  • Debug
  • Trace

Changing the Default Settings of Prime Optical Server and OSS CORBA Client Ports

For each connected OSS, JacORB uses several ports that have the following functions, as illustrated in Figure 12-3:

  • Session port—The main channel used for handshakes between the OSS and the CORBA gateway. The CORBA gateway assigns this port to a random value between free ports in the system.
  • Notification service port—The channel used to receive notifications from the CORBA gateway.
  • Name service port—The port used to request a new session. The value is always fixed; the default port number is 14005.
  • Session ping port—The channel used to establish a keep-alive handshake between the gateway and the OSS. The CORBA gateway assigns this port to a random value between free ports in the system.
  • Notification service event port—A second port range used to push alarms or events from the CORBA gateway to the OSS. This port is a keep-alive channel like the previous association to the notification channel.

Figure 12-3 Sample CORBA Gateway Static Port Settings

 

Caution Errors resulting from changing the Prime Optical server ports or the OSS CORBA client ports can cause unpredictable system behavior.

Note • It is recommended that you back up the current configuration files before changing the default settings.

  • You can change the default settings only for OSS CORBA client ports that use JacORB.

 

You can change the default values of the following ports:

  • OSS CORBA client ports:

– Object Adapter Port

– Source Port Range

– NAT Between the Prime Optical Server and OSS CORBA Client

  • Prime Optical server ports:

– NameService Port

– NotificationService Port

– EMSSession Port

– Ping Server-to-Client Port Range

– Notification Event Port Range

Note You can also set Prime Optical server port values from the Prime Optical GateWay/CORBA Service pane > Port Configuration tab. For more information, see Viewing the Prime Optical GateWay/CORBA Service Pane.

To set static values for CORBA gateway ports, it is strongly recommended that you follow these steps:

Step 1 With the Prime Optical server running, use the Control Panel to set the notification service port and the session port. See NotificationService Port and EMSSession Port.

Step 2 Enter the following command to stop the Prime Optical server:

opticalctl stop
 

Step 3 Switch off IMR. See Disabling IMR.

Step 4 Set the session ping port range. See Ping Server-to-Client Port Range.

Step 5 Set the name service port. See NameService Port.

Step 6 Set the notification service event port range. See Notification Event Port Range.

Step 7 Enter the following command to start the Prime Optical server:

opticalctl start
 

Step 8 Whenever you establish a new CORBA gateway session, use the netstat command to verify the actual ports in use and compare them to the newly added session.

 

Object Adapter Port

If you want to use a fixed port for the OSS CORBA client, change the value of the –DOAPort property. The –DOAPort property should be added to the file that launches the OSS CORBA client application. If there are two client instances running on the same machine, there should be two different port settings.

Source Port Range

Step 1 Open the jacorb.properties file from the OSS CORBA client directory.

Step 2 Change the value of the following properties:

jacorb.net.socket_factory=org.jacorb.orb.factory.PortRangeSocketFactory
jacorb.net.socket_factory.port.min=xxx
jacorb.net.socket_factory.port.max=yyy
 

 

NAT Between the Prime Optical Server and OSS CORBA Client

If Network Address Translation (NAT) exists between the Prime Optical server and OSS CORBA client, configure the jacorb.ior_proxy_host=xxx.xx.xx.xxx property from the jacorb.properties file to receive Prime Optical server callback messages and server-to-client pings. The xxx.xx.xx.xxx variable is the IP address of NAT inside global address.

NameService Port

Note You can also set the Name Service port value from the Prime Optical GateWay/CORBA Service pane > Port Configuration tab. For more information, see Viewing the Prime Optical GateWay/CORBA Service Pane.

jacorb.use_imr_endpoint=off
 

 

Changing the Prime Optical GateWay/CORBA Client Ports

In CTM R9.0 and earlier releases, Prime Optical GateWay/CORBA was installed and configured to use random ports and did not support a firewall between the OSS client and the Prime Optical server. Starting from CTM R9.1, you can install and configure Prime Optical GateWay/CORBA to use static ports, which facilitates the use of a firewall between the OSS client and the Prime Optical server.

Installation

When you install Prime Optical GateWay/CORBA, all of the ports are configured with default fixed values. See Table 12-9 for the list of default fixed values.

Note To configure Prime Optical GateWay/CORBA to use static ports, you must switch off IMR. See Configuration.

 

Table 12-9 List of Parameters and Fixed Values
Parameters
Default Fixed Values

EMS Session Port

20100

Name Service Port

14005

Notification Service Port

20001

Session Ping Port range

20101–20199

Event Notification Port range

20002–20099

IMR

Off

Proxy Host Address

Not set

Note It is recommended that you change the default fixed values after the Prime Optical GateWay/CORBA installation is complete. If you change the values while installing Prime Optical GateWay/CORBA, the installation might fail.

Configuration

Note • You can also configure Prime Optical server ports from the Prime Optical GateWay/CORBA Service pane > Port Configuration tab. For more information, see Viewing the Prime Optical GateWay/CORBA Service Pane.

  • Prime Optical GateWay/CORBA must be stopped in order to configure ports.

Step 1 Log in to the Prime Optical server as the root user.

Step 2 Invoke the manageCTMCorbaPorts.sh file from the Prime Optical-server-installation-directory /bin directory.

Note If Prime Optical GateWay/CORBA is running, you only have the option to read port configuration settings.

The following appears:

--------------------------------------------------
Manage CTM GateWay/CORBA Ports Utility
--------------------------------------------------
1. Read Configuration Set
