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

Click Create and choose Ethernet CFM→Create Global MEG. The Global Maintenance Entity Group, Test (Create) form opens.

Configure the required general parameters.

Perform one of the following:

1. To choose an existing MD, select an MD in the Maintenance Domain panel.

2. To create a new MD:

   1. Click Create. The Maintenance Domain, Global Policy (Create) form opens.

   2. Configure the required parameters.

   3. Save the changes, close the form and select the MD you created.

Configure the required parameters in the Maintenance Entity Group panel.

If you select icc-based as the Name Format, the associated Name value must be 8 to 13 characters.

Configure the required parameters in the Initial MEG Configuration panel.

When you are creating a Global MEG for a 7750 SR-c4, 7750 SR-c12, or 7450 ESS-6, the Initial CCM Interval must be set to 1s.

You can only configure the Initial CFM Hold Down Timer (Centiseconds) parameter when the Initial CCM Interval is set to 10 ms or 100 ms.

When the Initial CCM Interval parameter is set to 10 ms or 100 ms, you cannot configure automatic MEP creation.

As required, associate a Service to the Global MEG. Perform Step 7 of To configure an Ethernet CFM MD policy and subordinate objects .

As required, add an Ethernet path to the Global MEG. Perform Step 8 of To configure an Ethernet CFM MD policy and subordinate objects .

As required, add a managed MEP to the Global MEG. Perform Step 10 of To configure an Ethernet CFM MD policy and subordinate objects .

Save the changes and close the form.

To run the OAM diagnostic test and view the results, perform To run one or more OAM diagnostic tests from the STM and view the test results . See To interpret OAM diagnostic test results on the STM for information about how to interpret the test results.
