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:
-
Generate specific flow-based traffic across the network to help identify flow-based issues.
-
Identify the impact of QoS settings (for example, SAP profile or QoS policies) on the overall traffic.
-
Check the throughput across a provider network. The throughput is displayed on the NFM-P GUI for each iteration of the test.
-
Debug flow-specific traffic forwarding across the provider network.
-
Analyze the behavior of various user-defined traffic patterns across the provider network.
-
Perform on-demand testing and results monitoring using a central entity.
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:
-
A CPE SLA Test-Head Group profile can contain up to eight stream/flows.
-
A CPE SLA Test-Head Group profile can contain up to eight analyzers.
-
When you configure the STM test execution details, the analyzer test name and the generator test name must be the same.
-
If the analyzer has a test (flow) which is not in the generator group profile, the test is not valid.
-
When you run a CPE SLA test or test group, only one test can be run at a time. You cannot run concurrent tests on the same device.
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.
|
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: 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:
|
9 | Configure the required feeder port for the generator.
|
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:
|
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 | Click on the CPE SLA Test Group Members tab, then click Create. The CPE Test-Head Group Profile form opens. |
18 |
Save your changes and close the forms. |
Run the STM test and analyze the results | |
19 |
On the Service Test Manager (STM) form, choose one of the following options from the object drop-down menu, then click Search.
|
20 |
Choose the appropriate CPE SLA test and click Execute to run the test. |
21 |
To view the test results, click on the Results tab. |
