Setting Up Service Level Contracts and Service Level Agreements

Setting Up Service Level Contracts and Service Level Agreements

The SLM administrative framework is designed to help you create and manage SLCs and SLAs using a wizard GUI design. This chapter contains:


Note This chapter includes information on setting up new folders, SLCs and SLAs. To modify or delete existing folders, SLCs, and SLAs see the chapter "Modifying Service Level Contracts and Service Level Agreements".

Overview

Now that SLM is installed and at least one ME 1100 Series is configured, you are ready to configure the SLM application for use. You launch SLM from the CiscoWorks2000 Server desktop, as shown in Figure 3-1.


Note If you have not yet configured at least one ME 1100 Series, see the chapter "Setting Up the Management Engine 1100 Series".


Figure 3-1: CiscoWorks2000 Server Desktop


From the desktop, you select the Service Level Management drawer. The activated drawer displays a green LED and the top-level folders are listed, as shown in Figure 3-2.


Figure 3-2: CiscoWorks2000 Desktop Server---Service Level Management Drawer


Top-level folders are:

To begin setting up SLCs, from the CiscoWorks2000 server desktop, you select Service Level Management>Administration>Service Level Manager>
Define Service Contracts
.

The Cisco Service Level Manager window opens, as shown in Figure 3-3. This is the SLM administrative window from which all SLC administrative functions are initialized.


Note You are prompted to install the Client Application Manager (CAM) when you click a SLM file in the navigation tree. CAM can speed up the time needed to download applications after the first invocation. Restart your browser when CAM installation is complete.

SLM enables you to organize your SLCs into folders. For example, you can have a different folder for each internet service provider (ISP) or organization with which you have an SLC.

The first folder in the SLM navigation tree is called Default. It is used to store SLC information when a new folder is not designated for your SLCs.

There are three basic steps when preparing to set up a new SLC, as shown in Table 3-3.


Note Before setting up SLCs and SLAs, you must have at least one ME 1100 Series installed and configured on your network, and fulfill the requirements using the SLM administrative GUI framework. See the chapter "Setting Up the Management Engine 1100 Series".

Defining SLA Type

SLM is designed to monitor three SLA types:

When setting up a new SLA, consider the following naming conventions:

Round-Trip Response

Round-trip response monitoring measures round-trip delay between two hosts, which is the total time required for a single packet or datagram to be sent from one machine, received by another machine, then returned to the original machine.

Round-trip response operation types are ICMP echo or UDP echo.


Note If you are monitoring UDP echo, you need to enable the SA Agent responder on all target devices. Telnet to the router and enter service udp-small-servers at the command prompt.

Procedure


Step 1 From the Define SLC window, select New>Round-Trip Response, as shown in Figure 3-10.

1For SA Agent operation commands, see the appendix "Best Practices and Sample Configurations".

Procedure


Step 1 Select the SLA source device(s) from the left column and target device(s) from the right column.

The devices listed in the source device(s) column have the required Cisco IOS software running that supports SA Agent version 2.1.0 or later.


Note If the metrics being monitored does not require Cisco IOS on the target device, you can enter the device name in the Device field.

If your target device is not listed in the inventory database, you can enter the device name in the Device field. You must make certain, however, that the device is registered with DNS if you use a hostname.

For example, if you are monitoring connectivity to a switch, you can enter the switch information in the Device field (for example, Cat6000.cisco.com).

Step 2 Click Add.

The SLA device pair is now listed in the device pair table.


TimeSaver If you are defining an SLA with multiple device pairs and each device pair is measuring the same operation type, you can highlight several source devices and target devices at one time, then click Add. The newly defined device pairs are automatically associated so that the first highlighted source device is paired with each highlighted target device. The second highlighted source device is paired with each highlighted target device, and so on.

1You do not need to know which Cisco IOS version is loaded on hardware devices; the SLM application automates the information for you.

Procedure


Step 1 Select the SLA source device(s) from the left column and select target device(s) from the right column.

The devices listed in the source and target windows lists only the devices that have the required Cisco IOS software running that supports the metrics being monitored.

When you monitor jitter, both the source device and target device must be a Cisco device that supports the SA Agent version 2.1.0 or later. In other words, only Cisco devices running Cisco IOS version 12.0(5)T or later or 12.0(8)S or later can measure the jitter operation.


Note The target device must have rtr responder enabled.

Step 2 Click Add.

The SLA device pair is now listed in the bottom frame of the Select Devices window, as shown in Figure 3-29.

TimeSaver If you are defining an SLA with multiple device pairs and each device pair is measuring the same operation type, you can highlight several source devices and target devices at one time, then click Add. The newly defined device pairs are automatically associated so that the first highlighted source device is paired with each highlighted target device. The second highlighted source device is paired with each highlighted target device, and so on.


Note The source device must always be different from the target device, or the device pair will not be accepted.

Step 3 Click Next.
