Provisioning Pseudowires

Pseudowire provisioning is the process of creating, modifying, or deleting pseudowires between end points and pushing the configurations corresponding to the pseudowire to the devices.

The pseudowire L2circuit provisioning wizard has four steps.

Step 1: Select the source and destination devices

In this step you choose the devices for source and destination of pseudowire.

You can select one of the device groups from a list of device groups already created by selecting the radio button "Select device groups". Alternatively, you can create device groups by grouping devices dynamically based on one of the following filtering criteria: location, name, hostname, or model

You can also directly select devices that are already added to JUNOScope by selecting the Select Devices Directly radio button. In this case, all devices that are added to JUNOScope are listed in the Select Devices list so that you can choose the devices from the list.

To select source and destination devices:

1. Select an option button to specify whether you wish to Select Devices Directly or Select a Device Group.
2. If you choose to select devices directly, you can either select the devices from the Select Devices list or filter the list of devices to generate a subset of devices based on the criterion of your choice. To filter the list of devices:
   1. From the Select a Field drop-down list, select one of the following options: Device Name, Device Hostname, Model, Location, and Comment.
   2. From the Select an Operator drop-down list, select one of the following options: Contains, Does not contain, Starts With, Ends With, and Equals.
   3. Enter a string and click View to display a list of devices that meet the criteria specified in the preceding steps.

   For example, to list devices that have device names starting with J, select Device Name from the Select Field drop-down list, Starts With from the Select an Operator drop-down list, enter J in the text box, and click View. All devices that have device names starting with J will be listed in the Select Devices list.

3. Click Next to go to Step 2 of the wizard.

Step2 Add/Edit/Delete Pseudowire

In this step you can create, modify, delete, or view pseudowires.

Pseudowires already provisioned or newly created for provisioning for the devices that are selected in step 2 of the wizard are shown at the bottom of wizard.

• You can select a pseudowire from the list and click Edit to modify the details. You can select a pseudowire from the list and click Delete to delete it.
• You can select a pseudowire from the list and click Force Deploy to redeploy the pseudowire configuration on devices without making any modifications to the pseudowire configuration

To add or modify a pseudowire:

1. Select the Source Device Name and Destination Device Name from the respective drop-downs.
2. Select and Interface Type. The options are: TDM (SAToP), ATM, and Ethernet
3. Select a Template and Select a Tunnel from the respective drop-downs. The templates in the drop-down depend on the interface type selected.
4. Specify the Virtual Circuit ID and provide a Description. The description is optional.

   If the Virtual Circuit ID is not specified, a Virtual Circuit ID is automatically generated for the pseudowire.

5. If the template type is ATM II, specify the VCI and VPI . These will be the same for both endpoints. If the interface type is not ATM, then these fields are disabled.
6. If the interface type is Ethernet, specify the VLAN ID. VLAN ID is the same for both endpoints. If the interface type is not Ethernet, then this field is disabled.
7. For the Source Endpoint and Destination Endpoint, specify the following:
   1. Device Name
   2. CE Interface: CE-facing interface. The drop-down lists the interfaces available for the endpoints specified.
   3. LSP Name: The drop-down list displays all LSPs configured on the endpoint devices that you have specified. LSP Name is mandatory if the selected end point is a BXOS device. LSP Name is optional if the end point is a JUNOS device.
   4. Logical Unit (number): If you do not specify this, the system automatically assigns a number.
   5. If the pseudowire is to be provisioned over a GRE tunnel, select a GRE Interface and a Logical Unit for the interface.
8. Click Add Entry. The pseudowire is listed at the bottom of the wizard.

The table at the bottom of the wizard displays:

• State: State can be one of the following:
  • New: If the pseudowire is new.
  • Modified: If an exiting pseudowire is modified.
  • Unchanged: If an existing pseudowire is unchanged.
• Source Device Name
• Source CE Interface
• Destination Device Name
• Destination CE Interface
• Virtual Circuit ID

Step 3: Confirm Add/Edit/Delete Pseudowire selections

In this wizard you can Confirm the addition, modification, or deletion of the pseudowire; or go back to the Previous step.

Click Confirm to go to Step 4 of the wizard

Step 4: Provision Pseudowires

In this step configurations are generated for pseudowires created in step 3 and are pushed to the devices.

Configurations can be pushed either immediately or can be scheduled for a late time. Alternatively, pushing the configuration can be saved as a named operation.

To provision the pseudowires configured to the devices

1. Select the Now radio button to push the configuration to the devices immediately.
2. Select the save Operation As button radio button and provide a name for the operation. The configuration can be saved as a named operation.
3. Select the Schedule radio button to select a schedule. The configurations will be pushed at the scheduled time.

   Note: The schedule can be chosen from those defined in Settings.
