Creating a Multisegment Pseudowire Service Definition

To specify the UNI settings for a multisegment pseudowire:

1. Fill in the fields as indicated in Table 1.

   Table 1: UNI Settings for a Multisegment Pseudowire

   Field	Action
   PE-CE Traffic Treatment
   Ethernet option	Select an Ethernet option from the list. The Ethernet option you choose determines the other options you can select and specify on the page.
   Customer traffic type	Select the Customer Traffic Type from the list. For port-to-port services, all traffic is always transported.
   VLAN Normalization	Select a value: Swap Normalize to Dot1q—To transport only single-tagged frames across the network core. All port, dot1q , and Q-in-Q traffic is transported across the network. For more information on VLAN normalizations for LDP signalling type, see Table 2 . For more information on VLAN normalizations for BGP signalling type, see Table 3. Note: Starting with Release 1.0R2, when you newly install Connectivity Services Director, if you select the option to not require normalization in a service definition, the auto-pick option for VLAN IDs and the option to edit the auto-pick behavior in service order are disabled in the service definition. When you create a service order by associating with that service definition, you need to manually enter the VLAN IDs for the interfaces and cannot use the auto-pick functionality. This same behavior also applies to default service templates in which if you select the normalization-not-required functionality, the auto-pick option for VLAN IDs is disabled. For more information about VLAN normalization, see Junos Space Layer 2 Services Overview. For information about VLAN manipulation, see Understanding VLAN Manipulation (Normalization and VLAN Mapping) on Ethernet Services.
   Auto Pick VLAN ID	Indicate how the VLAN ID is determined. By default, this check box is disabled. Clear this check box to allow the service provider to specify the VLAN ID. This option is normally used when no VLAN normalization is applied. Specify the VLAN ID range in VLAN range for manual input. Note: Make sure to select Editable in Service Order if you want the service provisioner to be able to override this setting. Select this check box when VLAN normalization is applied. Specify the VLAN ID pool in VLAN range for auto-pick. Note: Make sure to select Editable in Service Order if you want the service provisioner to be able to override this setting. Note: When the range of VLAN IDs that are automatically assigned by the system (with the auto-pick option enabled during the creation of a service definition) is less than or greater than the range of VLAN IDs that are manually specified (with the manual selection option enabled during the creation of a service definition), the following conditions apply during the creation of a service order with the Editable in Service Order check box selected during service definition creation: If you create a service order with the auto-pick option enabled, the VLAN ID is selected from the auto-pick range, and the value is displayed in the VLAN range for manual input field. If you attempt to change the VLAN ID manually, the value is restricted to the manually configured range. If you create a service order with the auto-pick option disabled, the VLAN ID is selected from the manually configured range, and the value is displayed in the VLAN range for manual input field. If you attempt to change the VLAN ID manually, the value is restricted to the manually configured range.
   VLAN ID range for auto-pick	Enter the VLAN ID pool. Range: 1 through 4094
   VLAN ID range for manual input	Enter the VLAN ID range. Range: 1 through 4094
   PE-CE Encapsulation
   Physical Interface	Select the physical interface encapsulation method for the MS-PW.
   Logical Interface	Select the logical interface encapsulation method for the MS-PW.
   PE-CE MTU Settings
   Editable in service order	Select this check box to allow the service provisioner to override the MTU setting.
   Interface MTU (Bytes)	The default MTU value is 1522 bytes. To allow the service provisioner to override the MTU setting, select the Editable in Service Order check box.
   MTU Range (Bytes)	In the MTU range fields, enter the lowest and highest values for MTU for each UNI. Note: To allow the service provisioner to override the MTU setting, select Editable in Service Order and, in the MTU range fields, type the highest and lowest MTU values.
   PE-CE QoS
   Enable QoS	When you enable QoS in the service definition, you can specify a QoS profile in the service order to classify traffic into defined service groups to provide the special treatment of traffic across the network service. For example, voice traffic can be sent across certain links, and data traffic can use other links.
   PE-CE Bandwidth
   Enable Rate Limiting	To enable a service provisioner to limit the available bandwidth, select this check box, and type a default bandwidth limit. Note: Bandwidth settings are available in the service definition when Manage CoS Profiles page is configured with CoS profiles.
   Bandwidth (Mbps)	Enter the default bandwidth value, in Mbps. Default: 10 Mbps Range: 1 Mbps through 100,000 Mbps
   Min Bandwidth (Kbps)	To override the default bandwidth value, select the Editable in Service Order check box. Enter the minimum bandwidth value in Kbps. Default: 1000 Kbps Range: 64 Kbps through 100,000 Kbps
   Max Bandwidth (Kbps)	Enter the maximum bandwidth value, in Mbps. Default: 100 Mbps Range: 1 Mbps through 100,000 Mbps
   Increment (Kbps)	Enter a value in the range that is made available to the service provisioner.
   Burst Size	Select the preferred option for calculating the burst size: MTU Based If you select the option MTU Based, you can specify a value for MTU Factor in the range 1 through 1087902. The default value for MTU Factor is 10. Line Rate Based If you select the option Line Rate Based, you can specify a value for Burst Period in the range 1 through 7450 milliseconds. The default value for Burst Period is 1. Note: The Calculate Burst Size list is enabled only when you select the Enable rate limiting check box.

   Table 2 presents the available VLAN normalization options when signalling type is LDP and Enable Multi Segment Pseudowire is enabled:

   Table 2: VLAN Normalization for Multisegment Psuedowire with LDP Signalling Type

   Ethernet Option	Customer Traffic Type	VLAN Normalization
   port	N/A	Normalization to Dot1q tag
   dot1q	Transport single vlan	Swap Normalization to Dot1q tag
   	Transport vlan range	Normalization not required
   qinq	Transport single vlan	Swap Normalization to Dot1q tag
   	Transport all traffic	Swap Normalization to Dot1q tag
   asymmetric tag depth	(Identical to qinq)	(Identical to qinq)

   Table 3 presents the available VLAN normalization options when signalling type is BGP and Enable Multi Segment Pseudowire is enabled:

   Table 3: VLAN Normalization for Multisegment Psuedowire with BGP Signalling Type (for FEC 129)

   Ethernet Option	Customer Traffic Type	VLAN Normalization
   port	N/A	Normalization not required
   dot1q	Transport single vlan	Swap
   	Transport vlan list	Normalization not required
   qinq	Transport single vlan	Swap
   	Transport vlan list	Normalization not required
   	Transport all traffic	Swap
   asymmetric tag depth	(Identical to qinq)	(Identical to qinq)

   Field	Action
   Connectivity Settings
   Auto-pick VC ID	This field is available only if the Signaling type is LDP. Select this check box to cause Connectivity Services Director to assign a VC ID automatically from the VC ID pool. Clear this check box to allow the service provisioner to enter the VC ID. To allow the service provisioner to override the setting in the VC ID box, select Editable in Service Order.
   Auto-pick Route Target	Select this check box to enable route target to be configured automatically. Clear the check box if you want the route target to be manually configured. By default, manual configuration of route target is enabled. To override this setting in the service order, select the Editable in Service Order check box.
   Auto-pick Route Distinguisher	Define a route distinguisher option: Select the check box to enable the service provider to specify the route distinguisher. Select the check box to enable the route distinguisher to be selected automatically To override this setting in the service order, select the Editable in Service Order check box.
   MTU (Bytes)	Enter an MTU value in this field. The default value for MTU is 1522 bytes To see the permitted range for the MTU value, select the Editable in Service Order check box. The MTU range is 1522 through 9192.
   MTU Range (Bytes)	If you select the check box Editable in Service Order, you can specify a value range for MTU (in bytes). The permitted range for MTU is 1522 through 9192. Note: Connectivity Services Director establishes the MTU by multiplying the value you specify in the Default MTU (Bytes) field by the value you specify for MTU Factor.

2. Click Review to examine the settings configured for the E-Line MS-PW service definition.
