Configure MPLS Header Stripping

Before you configure MPLS Header Stripping, refer to MPLS Header Stripping – Rules, Notes, and Limitations.

The following table summarizes the required tasks to configure MPLS Header stripping to strip the incoming MPLS packets:

S.No

Task

Refer to..

1.

Configure the required MPLS labels at the chassis level.

Configure MPLS Labels on a Chassis

2.

Configure the required network or hybrid port.

Configure Ports

3.

Enable MPLS Header Stripping on the network or hybrid port that you configured in task 2.

Enable Header Stripping Protocol on Ports

4.

Configure a map.

Keep in mind the following details when you configure a map:

● Ensure that you select the network or hybrid port on which you enabled MPLS Header Stripping as the source port of the map.
● Configure the map rules with the following parameters:
o L2 parameters such as EtherType, MAC Destination, MAC Source, VLAN, or Inner VLAN.
o MPLS payload parameters such as IP Version, IPv4 Destination, IPv4 Source, IPv6 Destination, IPv6 Source, Protocol, UDA1, or UDA2.

For more details, refer to MPLS Header Stripping – Rules, Notes, and Limitations.

Create a New Map

 

Create a New Map

The following are the steps for creating a map:

1.   Check the status of the nodes and ports that you plan to use with the map.

For information about how to check the status of the nodes and ports, refer to Status of Line Cards/Nodes and Ports.

2. From the device view, go to Maps > Maps to open the Maps page.
3. Click New.
4. Enter the Map Information:
a. Enter an alias for the map.

Use an alias that helps identify the task and destination. For example, netflix_traffic_to_wireshark.

b. (Optional) Enter a description of the map. When adding a description, consider the following:
•   Use up to 128 characters, including spaces.
•   Enclose the description in quotation marks if the description is longer than one word.
•   To include double quotation marks (") inside the quotation marks, precede it with a backslash (\).

See also Configure MPLS Header Stripping.

c. Select the Type.

The map type can be Regular, First Level, Second Level, or Inline.

For detailed information about the types of maps, refer to Map Types

d. Select the map Subtype.

The map subtype can be By Rule, Pass All, or Collector.

For detailed information about Pass All, refer to About Map-passall Maps. For detailed information about Collector, refer to About Shared Collectors.

e. Enable the Pass Traffic checkbox if no rules match.
f. Enable the Control Traffic checkbox to pass the GTP control traffic (GTP-c) to all GigaSMART engines in a GTP engine group. A GTP engine group has multiple GigaSMART engine port members.

Note:  The Control Traffic checkbox is applicable only for GTP and is displayed only if the map type is configured as First level, and the map sub type is configured as By Rule.

5. Specify the Map Source and Destination.
a. From the Source and Destination drop-down list, select the required source and destination ports for the map. To create a port list, click Port Editor.

Note:  You can add a maximum of 324 ports in the Source drop-down list, if the ports are not attached to a GigaStream.

Note:  For details about port types that are supported for the different types of maps, refer to Port Lists.

b. If you have selected a circuit port in the Destination drop-down list, select the required circuit tunnel from the Encapsulation Tunnel drop-down list to encapsulate the traffic.

Note:  For details about circuit tunnels, refer to About Circuit-ID Tunnels.

c. If the map is used to redirect the decapsulated traffic to the required tool ports, ensure that you select the IP interface in the Source drop-down list. You must have attached the IP interface to the VXLAN or L2GRE tunnel. For details about VXLAN or L2GRE tunnels, refer to About Virtual Extensible LAN (VXLAN) Tunnels and About Layer 2 Generic Routing Encapsulation (L2GRE) Tunnels. From the Destination drop-down list, select the required tool ports.
d. If the map will use a GigaSMART operation, select the Header Stripping (MPLS) operation that you have created earlier from the GigaSMART Operations (GSOP) drop-down list.
e. If you select the tool GigaStream for the destination, you can view the utilization value for the GigaStream.
6. Add rules to the map.

To add rules to the map, do any of the following:

o   Use the Quick Editor. For details, refer to the Configure MPLS Header Stripping.
o   Import a map template by clicking Import.
o   Create a rule by clicking Add a Rule.

For detailed information about map rules, refer to Map Rules.

7. Set the Map Order by selecting the priority from the Priority list.

For details about map priority, refer to Map Priority.

8. Set the Map Permissions.

For details about map permissions, refer to Port Access and Map Sharing.

9. Set the Map Tag.

Select the required tag key and tag value to which the map must be associated. The tag key and the associated tag values must be created in advance in GigaVUE- FM. Refer to the "Tags" and "Role Based Access Control" sections in the GigaVUE Administration Guide for more details.

Note:  When you associate a map to a tag value, then the ports, port groups, port pairs, GigaStreams that belong to the map are also associated to the tags.
