To configure microwave backhaul services

Before you begin

Ensure that:

  • the physical links are configured (except for single-site service)

  • Ethernet rings are configured, if you are creating a service that includes one or more rings. Only linear VLAN services are supported on ring topology. Linear VLL services are not supported on ring topology.

Steps
 

Perform one of the following to open the Microwave Backhaul Service (Create) form:

  1. Choose Create→Service→Microwave Backhaul from the NFM-P main menu. The Microwave Backhaul Service (Create) form opens.

    1. Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

    2. Click Create→Microwave Backhaul. The Microwave Backhaul Service (Create) form opens.


Configure the parameters in the Customer panel.


Perform one of the following to configure the VLAN ID:

  1. Retain the default selection in the Auto-Assign ID check box.

  2. Disable the Auto-Assign ID and configure the VLAN ID.


In the Microwave Backhaul Service panel:

  1. Configure the Type parameter as VLAN, VLL, or Unknown.

  2. Configure the Drop Priority parameter if you need to define the minimum LAG bandwidth required to support the SDH data flow at the service level. See Applying drop priority to SDH data flow cross-connections on L1 Radio LAGs for more information.

    Note: You can also configure the Drop Priority parameter at the site level; see step Step 6; substep 4.


Configure the remaining parameters on the General form, as required, and click Apply. The Microwave Backhaul Service (Create) form is updated as Microwave Backhaul Service (Edit) form and additional parameters appear.


Perform one of the following to configure the P2P service path.

  1. Perform the following to configure the service path manually from the navigation tree:

    1. On the navigation tree, right-click on the Sites object and choose Create Backhaul Site. The Select Network Elements form opens.

    2. Choose a Wavence or a non-Wavence (7750 SR or 7210 SAS) site, as required, and click OK. The MBS Site (Create) form opens.

    3. Click on the MPR Site tab and configure the parameters based on the service type.

      If you set the Type parameter in Step 4 to:

      Then the Connection Type parameter in the Service panel is set to:

      VLAN

      Tagged Ports

      You can either change or retain the value.

      VLL

      Cross Connection

      You can either change or retain the value.

      Unknown

      unspecified

      You can configure the value as Tagged Ports, if your service is VLAN, and Cross Connection, if your service is VLL.

    4. Alternatively, configure the Drop Priority parameter if you need to define the minimum LAG bandwidth required to support the SDH data flow at the site level. See Applying drop priority to SDH data flow cross-connections on L1 Radio LAGs for additional information.

    5. Click on the Adjacencies tab and click Create. The Backhaul Adjacency (Create) form opens.

    6. Choose the port, and radio ring, as required, and click OK. The Site, Adjacencies, and Port objects appear below the Sites object on the navigation tree.

      Note: You can also configure the adjacencies by right-clicking the Adjacencies object and choosing Create Backhaul Adjacency.

      Note: For non-MPR sites, all radio ring options are listed. You need to select the Wavence radio ring for which the non-Wavence site is part of the topology.

  2. Perform the following to populate the path automatically:

    1. Click Populate Service→Search For Path. The Microwave Backhaul Service Path Search form opens.

    2. Choose the source site and destination site.

    3. Choose the source port and destination port, if required, and click Search. The path search results are listed.

    4. Choose the required path and click OK. The Site, Adjacencies, and Port objects appear below the Sites object on the navigation tree.

Note: The path search lists either VLL or VLAN path depending on the microwave backhaul service type configured. The path search does not list both VLL and VLAN paths.


Configure the Element Instance parameter to select the Ring Element instance (uniformly) in the path search.

For example:

  • Element Instance = 0 is given as input in the path search from Endpoint A to Endpoint B involving multiple rings each having more than one ring element instance (maximum 2); all the paths with ring element instance randomly selected in all the multiple rings, and shown as a result of the path search. Use this option for hop-based path searches.

  • Element Instance = 1 is given as input in the path search from Endpoint A to Endpoint B involving multiple rings, each having more than one ring element instance (maximum 2); all the paths with ring element instance 1 in all the multiple rings are chosen and shown as result of the path search.

  • Element Instance = 2 is given as input in the path search from Endpoint A to Endpoint B involving multiple rings, each having more than one ring element instance (maximum 2); all the paths with ring element instance 2 in all the multiple rings are chosen and shown as a result of the path search.

Note: After choosing a path search result and before applying the changes in the service template, there is an option to clear a ring instance pointer for any ring adjacencies on the Service form.

To change the ring instance pointer for all the ring adjacencies belonging to a specific ring:

  1. On the Service form, expand Service→Sites→Site→Adjacenies→Port and choose a ring adjacency.

  2. In the Local Adjacency Panel, press the Clear button associated with the Radio Ring parameter to delete the Port.

  3. Use the Select button associated with the Local Port parameter to select a new port.


Repeat Step 6 and Step 7 to configure a P2MP service path, if required.


Click Apply. The Microwave Backhaul Service (Edit) form opens with the updated parameters.


10 

Click Connect Service to connect the microwave backhaul service. The Connect Attempted check box is selected automatically.


11 

Check whether the Topology Misconfigured check box is selected. If selected, the check box indicates that the topology is misconfigured. The reasons for the topology misconfiguration are provided in the Microwave Backhaul Services panel on the MBS (Edit) form. Take the corrective action to eliminate the errors. The Topology Changed check box is selected automatically after the topology is modified.

Note: See Incorrect topology for more information about common causes of incorrect topologies.


12 

Click Connect Service again to attempt to connect the MBS. When all errors are eliminated, the Topology Misconfigured check box will be unchecked and the Reason for Topology Misconfiguration information will no longer be present on the form.

Note: You can skip Step 12, and go to Step 13 directly, if the connect operation fails even after the configurations are corrected. The operational state is not calculated in such cases.


13 

Click Deploy Service.

Result: The microwave backhaul service is configured successfully.

Note: See Non-MPR sites for additional information about deploying a service with non-MPR sites.
