Configuration of GCB Diameter Traffic Processing

This section provides information regarding the following:

■   Configure Traffic Policy
■   Configure GCB Settings

Rules and Notes

■   A minimum of 3 CPUs must be allocated for each GCB instance for better performance.

Configure Traffic Policy

To create a Traffic Policy in GigaVUE-FM:

1.   From the GigaVUE-FM left navigation pane, select Traffic > CONTAINER > Gigamon Containerized Broker. The Traffic Policy page appears.
2. In the Traffic Policy page, click Create. The Create Policy page appears. Enter or select the required information as described in the following table:

Fields

Description

Policy

 

Policy Name

Enter a name for the policy. The Policies with the same name are allowed when the traffic source for one policy is SBI and another is Diameter. In such cases, Traffic Type helps to differentiate between SBI and Diameter traffic.

Connection

Select a connection for the policy.

Connection Type

Select any one of the following connection types:

SBI - to create rules for the Service Based Interface (SBI) Application traffic.

Diameter - to create rules for the Diameter traffic.

3. Click Next to switch to the Tunnels tab. Enter or select the required information as described in the following table:

Fields

Description

Tunnel Name

Name of the tunnel.

Remote IP Address

IP Address of the Tunnel.

Tunnel Type

Select L2GRE or VXLAN as the tunnel type.

Tunnel Key

Enter a value for the tunnel key.

Destination Port

If the tunnel type is VXLAN, enter the tunnel destination port number.

Tool MTU

Enter the Tool MTU value. Enter a value between 156 and 9216.

When GCB sends the TCP packets through VXLAN or GRE tunnels, GigaVUE‑FM will use the specified Tool MTU value to segment the captured packets before sending them to the tool to avoid fragmentation.

  • By default, GigaVUE‑FM will display the Interface MTU value from the GCB Settings page in the Tool MTU field. For more details on Interface MTU value, refer to the General Settings section in Configure GCB Settings.
  • Modifying the Tool MTU value will only be effective if the functionality is enabled in GCB Settings.
  • If you do not specify any Tool MTU value, the packets will not be segmented.
  • GigaVUE‑FM will display an error if the specified Tool MTU value is greater than the Interface MTU value (default value configured in GCB Settings).
4. Switch to Rules tab. Enter or select the required information as described in the following table:

Fields

Description

Rules

Name

Enter a name for the Rule.

Destination Name

Select a tunnel destination.

Pass

Select Pass to allow the packets.

Click New Filter from the Actions drop- down to add filters for the rule.

Type

Select any one of the types from the following:

● F5 Metadata - Provide a Metadata field name and value, when you select this option. For fields, which are part of request-metadata and answer-metadata, should be entered with a "." notation.

For example: answer-metadata.error , etc.

● Kubernetes - Provide a value for the service, when you select this option.

Note:   For Diameter Traffic, Kubernetes filter type is not supported.

Filter Value

Enter a value for the filter type.
5. Click Create. The new Traffic Policy deploys itself in GCB.

The Traffic Policy processes the traffic and forwards the traffic to the tunnel destination IP address.
