1. Go to Configuration > Layer 2 > Services menu and click Complete Services option. The Complete Services page is displayed.
2. Search and select the hub and spoke service desired to modify. Double-click that service. A detailed page of the service is displayed.
3. Under Service Information column, click (Add) and select Switch to Hub and Spoke option.

7. For chosen node, select the check box against the port followed by entering the VLAN value for Regular mode or select the check box under All column for Transparent mode.

   If the service is in Qos domain, associate a Priority Mapping Profile or DSCP Mapping Profile or a pair of TCProfile and COS value.

   

8. Click Add Uni > OK. The endpoint and UNI gets added. Click Add Uni to add another UNI on same node, if desired. But only one node is allowed to be added.
9. Click Next. The Hub Selection page is displayed.

    • To add a spoke, select Spoke option from the Add node as drop down menu. Select the Disable Inter-Spoke Traffic check box, if desired. Select Hub check box against the switch desired followed by Backup Hub if Dual Homed check box is selected.

      

    • To add a hub, select Hub option from the Add node as drop down menu. Select Hub check box against the switch desired.

      

11. Click View Service to display the existing service path. Click Back to return to the Hub Selection page.
12. Click Next. PseudoWires page is displayed.

    • Under Qos Configuration, user can provide the pseudowire bandwidth by entering the A-End BW and Z-End BW values for particular queue.

      NOTE: Qos Configuration tab will be present when advanced configuration is selected.

    • To create an unprotected/protected pseudowire, un-select/select (Protection) check box under PseudoWires. The check box against the end points gets unchecked/checked simultaneously.
    • Pseudowire path selection can be done in two ways as follows:

    To find path for the pseudowire automatically,

    1. Enable Find Path button by selecting (Auto Path) check box and then select check box against the added end points. Check boxes will be selected by default.
    2. Click Find Path. A success message is displayed. Path is found successfully.
