To configure Layer 3 encapsulation on a source site to allow LI-mirrored packets to be placed into a routable header

Related information

You can configure a Layer 3 encapsulation option to allow LI-mirrored packets to be placed into a routable header (either IP-UDP Shim or IP-GRE) and then forwarded in a routing context.

The following conditions apply if you configure the Layer 3 encapsulation option:

  • Configuring Mirror SDP bindings and Mirror SAPs is mutually exclusive to the L3 Encapsulation

  • You cannot configure the Session ID or Intercept ID of a source later on in this procedure if the L3 Encapsulation is not configured here.

  • You cannot configure L3 Encapsulation if a mirror source object (such as: IP filter, MAC filter, and so on) is first configured for this service.

  • You cannot change the routing instance of L3 Encapsulation if a gateway is first configured for this service.

You can configure L3 Encapsulation only on a source site on an NE in chassis mode D. See Chapter 15, Shelf and card object configuration for more information about chassis modes.

Steps
 
1 

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

2 

Select a mirror service and click Properties. The Mirror Service (Edit) form opens.

3 

On the service navigation tree, expand Source Sites and click on the source site. The Mirror Site (Edit) form opens.

4 

Click on the L3 Encapsulation tab and click Create. The Layer-3 Encapsulation null (Create) form opens

5 

Configure the required parameters.

The Use Direction Bit parameter is only displayed if you configured the Header Type option for IP-UDP Shim.

6 

Select a routing instance ID in the Routing Instance panel.

7 

To configure a gateway:

  1. Click Create in the Gateway panel. The Layer-3 Encapsulation Gateway null (Create) form opens.

  2. Configure the required parameters in the IP Address panel.

    The gateway Source Address and Destination Address must either both be unconfigured or both configured. Similarly, the gateway Source Port and Destination Port must either both be unconfigured or both configured.

    The Source Port and Destination Port parameters are displayed only if you configured the Header Type option for IP-UDP Shim.

  3. Save the changes and close the form.

Save the changes and close the forms.
