EPL With C-Tag#

This example also expands on the first example and shows how to add service multiplexing using a Customer VLAN tag (C-TAG) and also how to enable per-CoS bandwidth profiles. We will create an EVPL service with a C-TAG value of 10, using bandwidth profiles for CoS value 1 and 5.

  1. Add a Xena chassis to the configuration (or re-use the one you already have).

  2. Create a new Ethernet service. Set the Service Type to EPL and check the Is Virtual checkbox.

  1. Go to the Bandwidth Profiles panel and create and configure two new profiles, one for each CoS value we want to use. The CIR/EIR values should preferably be different so that you can see a difference when you run the test.

  2. Add two suitable ports to the service. Assign each of the ports to a different direction group (EAST or WEST).

  3. Select both UNIs in the tree view and change to the Service/UNI Configuration panel. Check the VLAN: Customer Tag checkbox and set the C-tag value in the Frame Editor to 10.

  1. Change to the Ingress Bandwidth Profiles tab. Select the Use Per-CoS Bandwidth Profiles option.

  1. Press the Add button. Set the CoS value to 1 and select the first profile you created above. Ignore the DSCP settings and press OK.

  2. Add another CoS-profile mapping for CoS value 5.

  3. Save your configuration.

  4. Right-click on the service you just created in the Defined Services tree view and select the Run Configuration Test (for this service only) item.
