Create ELAN services with full mesh

A Full mesh network is a type of service where the node participating in the network also acts as a relay for the other nodes.

Perform the following steps to create an ELAN full mesh service:

Go to Configuration > Layer 2 > Services menu and click Complete Services option. The Complete Services page is displayed.
Click on . A series of new windows will be displayed for step-by step creation of a service.

  > Click (Add switches using map view). Select desired end points from the Topology selection window launched and click Done. Note that only one node can be added at a time.
3. For the selected endpoint, add Uni by selecting the check box against the desired port and do one of the following:
  > If Domain is selected as 'Non Qos Domain' or All Domain' in General Attributes page, enter the VLAN value only under First Tag column. For All Domain the UNI port can be associated with TCProfile and CoS-0.
  
  > If Domain is selected as 'Qos Domain', enter the VLAN value under First Tag column and associate a Priority Mapping Profile or DSCP Mapping Profile or a pair of TCProfile and COS values.
  
  To view the bandwidth utilization, select a port and click View BW. View Port BW Utilization window is displayed with the bandwidth utilization details of Ingress and Egress Port.
  
  To view the used VLAN range, select a port and click Show Used VLans. View Used VLAN Range(s) window is displayed with a list of used VLAN values for the selected port.

Step 3: PseudoWires

The PseudoWires page of Create Service provides the options to add or remove protection, selection of pseudowire path manually or automatic path detection, MA configuration, and Qos Configuration.

Create Full Mesh Service- Step 3 (PseudoWires)

To edit MA configuration parameters, click MA Configuration tab and select or enter the required values.
To add or remove protection on the pseudowires, select/un-select the (Protection) check box along with the check boxes against each of the two end points displayed under PseudoWires column. The check boxes will be selected by default.
To assign bandwidth at individual pseudowire level, select the desired endpoints and click Qos Configuration tab. For the predefined CoS value, user can manually assign the bandwidth (CIR and PIR) for A and Z end of the pseudowire.
NOTE 1: CoS Value at UNI ports would be considered for bandwidth calculation only if bandwidth values for the CoS is not specified for the Pseudowire.

NOTE 2: Service creation will fail if the bandwidth defined in TCProfile attached to any UNI port in the service is not available on the port. The user can then manually assign the bandwidth value for CIR and PIR in Qos Configuration tab.
PseudoWire path selection (both Work and Protect) can be done in two ways as explained follows:

To find pseudowire path automatically,

First enable Find Path button by selecting the (Auto Path) check box and the check boxes against the added endpoints. The check boxes will be selected by default.
Click Find Path. A success message is displayed. Path is found successfully.
Click OK and select a pseudowire endpoint (Sw1--Sw2) to view its path under the View tab.
Graphical representation of the pseudowire detected automatically is displayed under the View tab as shown in the following figure. Details of work and protect path, excluded switches and excluded tunnels are available under Details column:

NOTE: When finding the pseudowire path automatically, the user is provided an option to exclude switches/tunnels. Select Excluded Switches and Excluded Tunnels tab. Click Add button and select the desired nodes and/links. Click Exclude Nodes or Exclude Links followed by Done. Remove button can be used to delete the added data. Select Find Path. Pseudowire path is calculated once again, excluding the selected switches/tunnels in the path.

To find pseudowire path manually,

Un-check the (Auto Path) check box and select a pseudowire. The Manual Path button is displayed under the View tab.
Click Manual Path. The topology selection window is displayed.
There are two ways in which the pseudowire path can be added, which is explained as follows:
(i) Direct Path Selection: This option is used for direct path selection between two end points with no intermediate nodes in between and is applicable to both work and protect path.

Select a direct path/link between the two selected end points (highlighted in black) and click Add Work. The work path is added and the link color changes from pink to blue.

To add protection, select another direct path/link between the two selected end points and click Add Protect. The protect path is added and represented in blue dashed line.

Click Done. Graphical representation of the pseudowire added is displayed on the PseudoWires page under View tab along with work and protect path details under Details column as shown in the following figure:

(ii) Partial Link Selection: This option is used when the user has to add more than one link to create a pseudowire path between the two end points and is applicable to both work and protect path.

Select the Partial Link Selection check box. Select the path/link and click Add link. Similarly, add the additional links between intermediate nodes connecting the two selected end points. The path/link gets highlighted in cyan color. Click the Add Work. The work path is added and the link color changes from cyan to blue solid line.

To add protection, select Partial Link Selection check box again. Select the path/link and click Add link. Similarly, add the other links between intermediate nodes connecting the selected two end points and select Add Protect. The protect path is added and represented in blue dashed line.

Click Done. In case path addition fails, the partial link selection will be reset.

Graphical representation of the pseudowire added is displayed on the PseudoWires page under View tab along with work and protect path details under Details column as shown in the following figure:
Click Next.
NOTE: An additional PW Status Info page will be displayed if OAM was selected as 'Pw Status' on General Attributes page. For more information refer to Step 4: PW Status Info in the topic Create MPLS-TP service with PWSM.

Step 4: Advance Configuration

On Advance Configuration window, Storm Control Configuration is performed. Select the Enable Broadcast/MultiCast Stormcontrol check box if desired and then enter the BroadCast/Multicast Stormcontrol value in Mbps in the text box displayed. Click Next to view the summary of the ELAN service.
