Sample OmniSwitch device SLA testing

CPE SLA Test-Head OAM test

You can use the NFM-P STM to perform a CPE SLA Test-Head OAM test to validate and test customer SLAs used on select OmniSwitch devices in Metro Ethernet networks. The test is critical for provisioning or troubleshooting network services between customer endpoints. The CPE SLA Test-Head OAM test supports unidirectional traffic and IPv4.

You can perform the following tasks on the NFM-P without an external test-head device:

You can perform a CPE SLA Test-Head OAM test using one CPE test-head profile or a group of profiles. You can also run several tests for one CPE Test-Head profile or group of profiles.

The following conditions are applicable to the creation of a CPE SLA Test-Head profile or a group of profiles and their execution:

Sample CPE SLA Test-Head profile configuration

The following configuration steps describe how to create a CPE SLA Test-Head profile or a group of profiles on supporting OmniSwitch devices. For information about device support, see the NE documentation.

Note: For OS 6400, OS 6850E, OS 6855 U24X, and OS 9000E NEs running AOS Release 6.4.5, CPE SLA Test-Head profiles and CPE SLA Test-Head Group profiles can only be distributed if the profile has a Tx Rate of 64 kbps or above. If running AOS Release 6.4.6 or later, the Tx Rate must be 88 kbps or above.

CPE SLA Test-Head profile configuration steps

The procedure lists only the configuration steps that are required for this sample. See the procedures in Procedures to use the STM for complete STM configuration information.

Create a CPE SLA Test-Head profile
 
1 

Choose Tools→Y1564 Profiles→AOS CPE Test-Head Profile from the NFM-P main menu. The AOS CPE Test-Head Profiles form opens.

2 

Click Create. The AOS CPE Test-Head Profile (Create) form opens.

3 

Configure the required parameters.

Additional panels and parameters are available when you configure the Frame Type parameter or set the L2 Saa parameter to true.

4 

Click Apply, then click Switch Mode to change the configuration mode to Released.

5 

Distribute the CPE Test-Head profile to the required NEs. See Chapter 49, Policies overview for more information about policies and policy distribution.

6 

Configure the local VLAN and port settings for the CPE Test-Head profile.

  1. Click on the Local Definitions tab, then click Search. A list of the NEs to which you distributed the profile in Stage 5 is displayed.

  2. Choose an NE and click Properties. The CPE Test-Head Profile form opens.

  3. In the VLAN panel, click on the Select button for the Service ID parameter. The Select vlanSitePointer - CPE Test-Head Profile form opens.

  4. Click Search and choose a VLAN site.

  5. Click Local Audit On to change the mode to Local Edit only.

  6. Click on the Select button for the Port parameter. The Select vlan port - CPE Test-Head Profile form opens.

  7. Click Search and choose a port.

  8. Click Apply and close the form.

7 

As required, repeat Stage 1 to Stage 6 to create additional CPE SLA Test-Head profiles.

The CPE SLA test OAM diagnostic test on the STM (see Stage 10), can utilize the following profile types:

  • Generator profile

  • Analyzer profile

  • Loopback profile

You can also group profiles as described in Stage 8 ; otherwise, go to Stage 10.

Create an AOS CPE SLA Test-Head Group profile
 
8 

If required, create an AOS CPE SLA Test-Head Group profile which can be use to bind individual CPE Test-Head profiles to form a group of tests.

Perform the following:

  1. Choose Tools→Y1564 Profiles→AOS CPE Test-Head Group Profile from the NFM-P main menu. The AOS CPE Test-Head Group Profile form opens.

  2. Click Create. The AOS CPE Test-Head Group Profile (Create) form opens.

  3. Configure the required parameters.

    If the Role parameter is set to the Generator option, perform Stage 9. Otherwise, continue with Stage 8.

  4. Click on the CPE Test Group Member tab, then click Create. The Select Port - AOS CPE Test Group Profile form opens.

  5. Choose the required CPE Test-Head profiles and click OK. The AOS CPE Test-Head Group Profile (Create) form opens displaying the selected profiles.

  6. Click OK to save the AOS CPE Test-Head Group profile.

  7. Click Search to display the AOS CPE Test-Head Group profile.

  8. Choose the AOS CPE Test-Head Group profile and perform Stage 4, Stage 5, and Stage 6.

  9. Go to Stage 10.

9 

Configure the required feeder port for the generator.

  1. Open the Properties form for the required NE.

  2. Click on the Globals tab, then on the AOS OAM tab.

  3. Click on the Select button for the Feeder Port Name parameter. The Select Feeder Port form opens.

  4. Choose the required feeder port and click OK. The NE Properties form reappears.

  5. Save your changes and close the form.

  6. Perform the rest of the substeps in Stage 8.

Configure the CPE SLA test execution details on the STM
 
10 

Choose Tools→Service Test Manager (STM) from the NFM-P main menu. The Service Test Manager (STM) form opens.

11 

Click Create and choose one of the following options:

  1. AOS CPE→CPE SLA Test. This option allows you to run a test on a CPE test-head profile or a group of profiles. The CPE SLA Test (Create) form opens. Perform Stage 12 to Stage 16, and Stage 18 to configure this option.

  2. AOS CPE→CPE SLA Test Group. This option allows you to run several tests on a on a CPE test-head profile or group of profiles. The CPE SLA Test Group (Create) form opens with the General tab displayed. Complete Stage 12,  Stage 13,  Stage 16, Stage 17, and Stage 18 to configure this option.

12 

Configure the required parameters.

13 

Click Select in the Generator panel and choose a generator profile.

14 

Click Select in the Analyzer panel and choose an analyzer profile.

15 

Click Select in the Loopback panel and choose an loopback profile.

16 

Click on the Test Parameters tab and configure the required parameters.

17
