System Overview

The Cisco WAN Access Performance Management System (Cisco WAPMS) and Cisco CNS solution combines the comprehensive wide area network (WAN) service-level management system of Cisco WAPMS with Cisco CNS capabilities, providing an integrated performance management solution for Cisco ATM products.

The Cisco WAPMS/CNS solution addresses the needs of service providers who have an existing installed base of Cisco ATM routers or who plan to install Cisco ATM routers, and enterprise customers managing their own Frame Relay and ATM networks internally. Existing customers using Cisco WAPMS can easily add new devices and/or access technologies for WAN performance management.

Utilizing Cisco's programmable network capabilities, Cisco WAPMS automates the collection, interpretation, and presentation of performance management data. Cisco WAPMS provides real-time and historical troubleshooting Toolsets that can eliminate the need for remote dispatches, and provides performance monitoring, SLA validation and performance reporting for IP, Frame Relay, ATM, and private line connections, or combinations of these technologies.

This chapter includes the following topics:

• “System Architecture”—Cisco WAPMS and Cisco CNS system architecture components

• “System Security”—system security considerations

• “Bandwidth Utilization” section on page 1-3—approximates the WAN bandwidth consumed by Cisco WAPMS's management of a given router port

• “Features” section on page 1-3—key features of the Cisco WAPMS and CNS system.

For more information about Cisco WAPMS, see Chapter 1, “Overview,” in the Cisco WAN Access

Performance Management System Client User Guide, 2.0.

System Architecture

The Cisco WAPMS/CNS system includes the following components:

• Cisco devices—customer or provider edge routers (CEs and PEs) with Cisco IOS software installed. These routers are configured to support data upload to Cisco WAPMS.

• Cisco CNS Event Gateway software—software providing centralized device configuration management. It can be installed on the Cisco CNS Intelligence Engine (IE) 2100 Series hardware

• Cisco WAPMS Analysis Service Elements (ASEs)—network devices that collect network performance data

(14)

Chapter 1 System Overview System Security

• Cisco WAPMS Performance Archive Manager (PAM)—database server that stores and interprets the data.

• Cisco WAPMS Clients—desktop applications that present the data for analysis. Clients can be Platform Applicable Clients (PACs) or Web Clients.

In the Cisco WAPMS/CNS solution, Cisco routers with Cisco IOS software installed are configured to support data upload to Cisco WAPMS through the Cisco CNS Event Gateway, which communicates with the Cisco WAPMS PAM using TIBCO Rendezvous messaging (see Figure 1-1). The Cisco CNS Event Gateway software is operated from the Cisco CNS IE2100 appliance.

Figure 1-1 also shows the location of Cisco WAPMS and Cisco components relative to the WAN, the subscriber’s WAN equipment, customer premises equipment (CPE), and site local area networks. Figure 1-1 Cisco WAPMS and Cisco CNS System Components

System Security

When configuring the Cisco WAPMS system in a firewall environment, you must set up communication paths between Cisco IOS routers and the Cisco CNS Event Gateway, and the Cisco CNS Event Gateway and the Cisco WAPMS PAM. (See Figure 1-1.)

Each router must be allowed to connect to its Cisco CNS Event Gateway on TCP port 11011.

Because the use of a firewall puts the Cisco CNS Event Gateway and the PAM on different subnets, you must configure the TIBCO Rendezvous Routing Daemon on both systems as described in the

“Configuring TIBCO/Rendezvous Routing Daemon on the PAM” section on page B-1. Once that is accomplished, set up the PAM to connect to the Cisco CNS Event Gateway on TCP port 7501.

Note Because the use of routing daemons compromises performance, do not use a firewall unless it is absolutely necessary.

Enabling Cisco CNS Support on the PAM

This chapter explains how to install Cisco WAPMS with the CNS Event Gateway enabled and to configure this support on the Cisco WAPMS PAM.

Installing Cisco WAPMS with CNS Capabilities

When installing or upgrading Cisco WAPMS, you have the option of enabling support for the management of Cisco devices.

You can activate Cisco CNS support after installation through the PAM Manager. After you activate Cisco CNS support, the Cisco WAPMS PAM manages Cisco devices.

For detailed information about installing Cisco WAPMS, see the Cisco WAN Access Performance

Management System Installation Guide, 2.0. For information about using the PAM Manager, see

Chapter 4, “Managing ASEs Using PAM Manager,” in the Cisco WAN Access Performance Management

System System Administration Guide, 2.0.

Configuring Cisco Support on the PAM

Before a PAM can communicate with Cisco CNS gateway devices, you must enable Cisco CNS support on that PAM. You must also license the devices in PAM Administration. For more information, see “Configuring Licensing” section on page 3-19 in the Cisco WAN Access Performance Management

System System Administration Guide, 2.0.

Enabling Cisco CNS Support

Installing the Cisco CNS Event Gateway

This chapter explains how to install the Cisco CNS Event Gateway for use with Cisco WAPMS and how to verify connectivity with the PAM.

Configuring the Cisco CNS Event Gateway on the Cisco

CNS IE2100 Appliance

For the Cisco CNS Event Gateway to communicate with Cisco WAPMS, you must specify the IP address and password setting on the Cisco CNS IE2100 appliance.

When the Cisco CNS IE2100 is incorrectly configured, Cisco WAPMS cannot properly interface with Cisco devices. When you configure the Cisco CNS IE2100, make sure you do the following:

1. Log in as root, then run the setup program.

2. Leave all settings except for IP address values and passwords to the suggested defaults.

3. Set the IP address, subnet, and default gateway to appropriate values.

4. It is recommended for greater speed and bandwidth efficiency that you set up the PAM and Cisco CNS IE2100 on the same subnet. When you cannot set up the PAM and Cisco CNS IE2100 on the same subnet, see Appendix B, “Using the PAM and CNS Event Gateway on Different Subnets.”

5. Make sure the NSM Directives: value is set to default://.

6. Create an administrative name and password so root access to the Cisco CNS Gateway host machine is not required. The default root password is blender.

7. The # of Event Gateways N for serving 500 x N devices entry defaults to 1, which is sufficient for managing 500 routers. Increasing this number creates additional processes on the Cisco CNS IE2100, each of which can manage another 500 routers up to the Cisco CNS IE2100 maximum of 5,000 routers.

The following is an example session: [root@cns-cisco root]# setup

Entering Network Appliance Setup Type ctrl-c to exit

For detail information about the parameters in this setup, refer to “Cisco Intelligence Engine 2100 Series Configuration Engine Administrator's Guide.”

Interactive or non-interactive setup? 0=interactive, 1=non-interactive. [0]

Note: Modular router support is available only in internal directory mode. Choose operational mode of system. 0=internal directory mode, 1=external directory mode. [0]

Updating Cisco IOS Router Software

This chapter explains how to update Cisco IOS router software to a version supported by the Cisco WAPMS. It explains how to check memory requirements for the new software version, find the software version on the Cisco web site, perform the software upgrade, and verify the routers are functioning properly after the upgrade.

IOS Version Requirements

Cisco routers must have IOS software image 12.3(1) or later installed, to implement ATM and Frame Relay interface support with Cisco WAPMS.

Checking IOS Software Image Memory Requirements

Before installing a new Cisco IOS software image on your router, check if your router meets the memory requirements for that image. You must check how much Dynamic RAM (DRAM) and Flash are installed in the router and what software image version is installed. To do this, issue the show version command on your router and look for the following lines:

Router# show version

...

System image file is “flash:c827v-y6-mz.121-1.XB”

CISCO C827-4V (MPC855T) processor (revision 0x502) with 15360K/1024K bytes of memory. ...

8192K bytes of processor board System flash (Read/Write)

Add the DRAM and Flash memory together to find the total memory installed. In this example, it is 16MB.

For more information, see the Cisco web site: http://www.cisco.com

For information about using the Cisco IOS command-line interface, see the Cisco CNS 1.5 Administrator Guide or the Cisco IOS Interface Command Reference release 12.2 or later.

Configuring Basic Router Settings

To configure the basic settings for the Cisco router to communicate with Cisco WAPMS, you must:

• specify the IP address of the Cisco CNS IE2100

• specify the name of the interface used to identify the router

• enable the measurement of ATM or Frame Relay service level monitoring statistics

• enable the generation of SNMP traps through Cisco CNS and Cold Start traps

(26)

Chapter 5 Configuring Cisco IOS Routers for Cisco WAPMS Support Configuring Basic Router Settings

Configuring Basic Settings on the Cisco Router

Step 1 At the Cisco IOS command-line interface, enter “executive” mode, which allows you to edit the router’s configuration:

Router# enable Router#

Step 2 Press Enter:

A password may be required.

Step 3 To change the router’s actual configuration, you must enter “configuration” submode: Router# config terminal

Router(config)#

Step 4 Enter the IP address of the Cisco CNS Event Gateway to connect to for Cisco CNS management: Router(config)# cns event <ip address of CNS gateway> [port number] keepalive 300 3

For example: cns event 10.1.2.3 keepalive 300 3. It is recommended you leave the port number at the default setting of 11011.

An optional, backup Cisco CNS Event Gateway may also be configured:

cns event 10.1.2.4 backup

Step 5 Enter the name of the interface whose IP address will be used to identify the device to Cisco WAPMS: Router(config)# cns id <interface> ipaddress event

When IP connectivity between the router and the Cisco CNS Event Gateway is through a WAN interface, enter that interface name (such as, ATM 0). Similarly, when IP connectivity is through a LAN interface, enter that interface name (such as, Ethernet 0). For example:

Router(config)# cns id atm 0 ipaddress event

Step 6 Enable the measurement of service level monitoring statistics for ATM: Router(config)# atm slm statistics

For Frame Relay:

Router(config)# rtr slm frame-relay statistics

Step 7 Enable the generation of SNMP traps through Cisco CNS: Router(config)# cns notifications encapsulation snmp

Step 8 Enable the generation of the SNMP Cold Start traps: Router(config)# snmp-server enable traps snmp coldstart

Step 9 Ensure index numbers remain constant when interfaces are added or removed: Router(config)# snmp-server ifindex persist

(27)

Chapter 5 Configuring Cisco IOS Routers for Cisco WAPMS Support

Configuring the Physical Interface

Step 10 Check to see if an SNMP server host is configured: Router# show running-config | include snmp-server host

When a host is configured, skip this step. When a host is not yet configured, use the loopback address as a dummy destination:

Router(config)# snmp-server host 127.0.0.1 public

Step 11 Continue on to the next section, “Configuring the Physical Interface”.

Configuring the Physical Interface

Once you have completed the basic router configuration, you are ready to configure the physical and then link interface settings. When modifying or adding new interfaces or circuits, you must add response time report (RTR) operations for them. Repeat this sequence of steps for each new network interface.

Note For each network-side physical interface and network-side link interface you configure on the router, you must use a RTR operation. For each interface, you will also configure the history collection to use 100 15-minute samples, and then enable the RTR operation.

Note To ensure Cisco WAPMS obtains the correct line speed from the router, the IOS interface-level bandwidth command must be used to set the line speed properly. Interfaces that exhibit this behavior include:

* NM-4T four port serial network module (for example, V.35 and RS-232) * 1602-R built-in 56/64K DDS interface.

For a listing of type command line options for your router, see Table 5-1. For examples of specific router configurations, see Appendix A, “Sample Cisco IOS Router Configuration.”

Configuring the Cisco Router Physical Interface

Step 1 Define a new RTR operation:

rtr <id>

where <id> is any positive integer and is used to uniquely identify the operation. For example: rtr 1.

Step 2 Enable SLM on the physical interface (for example, T1 0 to collect DS1 history on that interface controller). Use the following example as a reference. At the type details command line, see Table 5-1 for options for your router.

Router(config)# rtr 1

Router(config-rtr)# type details...

Router(config-rtr-slm)# enhanced-history interval 900 buckets 100 Router(config-rtr-slm)# exit

(28)

Chapter 5 Configuring Cisco IOS Routers for Cisco WAPMS Support Configuring the Link Interface

Step 3 When you have completed configuring the router’s physical interface, go to the next section “Configuring the Link Interface”.

Configuring the Link Interface

After completing physical interface settings, you are ready to configure link interface settings. When modifying or adding new interfaces or circuits, you must add RTR operations for these. Repeat these steps for each new network interface.

For a listing of type command line options for your router, see Table 5-2. For examples of specific router configurations, see Appendix A, “Sample Cisco IOS Router Configuration.”

Configuring the Cisco Router Physical Interface

Step 1 Enable SLM on the link interface (for example, ATM 0 to collect ATM history on that interface). Use the following example as a reference. At the type <details> command line see Table 5-2 for options for your router.

Router(config-rtr)# type <details>...

Router(config)# rtr schedule 2 start-time now life forever

Configuring Circuits

Step 2 When you have completed configuring each physical and link interface, go to the next section, “Configuring Circuits”.

Configuring Circuits

When modifying or adding new interfaces or circuits, you must add RTR operations for these. Repeat Step 1 for each new circuit.

Note Before configuring the Cisco router, ensure you have oam-pvc manage enabled on all your ATM circuits and that all circuits are running properly.

For examples of specific router configurations, see Appendix A, “Sample Cisco IOS Router Configuration.”

Configuring Cisco Router Circuits

Step 1 Enable SLM for each circuit. When you have completed configuring each circuit, go to Step 2. Use the following example as a reference. For example (where rtr 10 indicates a new sequence from the examples in the “Configuring the Physical Interface” section on page 5-3). At the type <details> command line, see Table 5-3 for options for your router.

Router(config-rtr)# type <details>...

Router(config)# rtr schedule 10 start-time now life forever

Step 2 Enter:

Router(config-rtr)# exit

Troubleshooting

This chapter explains how to troubleshoot Cisco IOS router and Cisco CNS Event Gateway setup and configuration.

The following topics are discussed:

• “CNS Event Gateway Setup”

• “CNS Event Gateway and PAM Communication”

• “CNS Event Gateway and Router Connectivity”

• “Router Configuration” section on page 7-2.

CNS Event Gateway Setup

When configuring the Cisco CNS Event Gateway on the Cisco CNS IE2100, ensure the

NSM Directives: value is set to default://.

CNS Event Gateway and PAM Communication

Once you have configured the Cisco CNS Event Gateway, verify the PAM and Cisco CNS Event Gateway are communicating. Point a browser to the following URL:

http://<ie2100's IP>:7580/hosts?7500 The IP address of the PAM should be shown.

It is recommended for greater speed and bandwidth efficiency that you set up the PAM and Cisco CNS IE2100 on the same subnet. If the PAM and Cisco CNS Event Gateway are not communicating and they are on different IP subnets, you must enable the Rendezvous Routing Daemon. For more information, see Appendix B, “Using the PAM and CNS Event Gateway on Different Subnets.”

(38)

Chapter 7 Troubleshooting CNS Event Gateway and Router Connectivity

CNS Event Gateway and Router Connectivity

To verify connectivity between the Cisco CNS Event Gateway and the router, do the following:

Step 1 Ensure the router is properly registered with the Cisco CNS IE2100. To check this, point a browser to: http://<ie2100's IP>:7580/subs?7500

Step 2 The IP address you are using to add the device in Cisco WAPMS should be listed as:

cisco.cns.slm.<IP addr>.

If it is not listed, check the cns event and cns id IOS command settings on the router.

Step 3 Enter show cns event connections at the router’s command line interface.

Ensure the IP address of the PAM is shown under the heading “Currently connected event gateway”.

Step 4 Verify the router and Cisco CNS Event Gateway are exchanging messages. Enter show cns event stats at the router’s command line interface.

Examine the counts of events received and events sent.

Router Configuration

It may take up to fifteen minutes after the RTR operation is entered for the router to start collecting statistics.

On a Cisco 3600 series T1/E1 IMA router, when you issue the shutdown/no shutdown commands, you must re-enter the RTR operation for each network side interface (see the “Configuring the Physical Interface” section on page 5-3). Before issuing shutdown/no shutdown commands, collect data from the router. From the PAC, select File > Collect Data Now.

When modifying or adding new interfaces or circuits to a router, you must add RTR operations for them in order for them to be monitored by Cisco WAPMS.

If you change circuit level parameters on a router, such as SCR or encapsulation type, you may need to re-enter the RTR operation. Before changing circuit level parameters, collect data from the router. From the PAC, select File > Collect Data Now.
