Defining a Logical Device

About Device Clusters

A device cluster (also known as a logical device) is one or more concrete devices that act as a single device. A device cluster has cluster (logical) interfaces, which describe the interface information for the device cluster. During service graph template rendering, function node connectors are associated with cluster (logical) interfaces. The Application Policy Infrastructure Controller (APIC) allocates the network resources (VLAN) for a function node connector during service graph template instantiation and rendering and programs the network resources onto the cluster (logical) interfaces.

The Cisco APIC allocates only the network resources for the service graph and programs only on the fabric side during graph instantiation. This behavior is useful if your environment already has an existing orchestrator or a dev-op tool that programs the devices in a device cluster.

The Cisco APIC needs to know the topology information (logical interface and concrete interface) for the device cluster and devices. This information enables the Cisco APIC to program the appropriate ports on the leaf switch, and the Cisco APIC can also use this information for troubleshooting wizard purposes. The Cisco APIC also needs to know the relation to DomP, which is used for allocating the encapsulation.

A device cluster or logical device can be either physical or virtual. A device cluster is considered virtual when the virtual machines that are part of that cluster reside on an hypervisor that is integrated with Cisco APIC using VMM domains. If these virtual machines are not part of a VMM domain, then they are treated as physical devices even though they are virtual machine instances.


Note

You can use only a VMware VMM domain or SCVMM VMM domain for a logical device

The following settings are required:

  • Connectivity information for the logical device (vnsLDevViP) and devices (CDev)

  • Information about supported function type (go-through, go-to, L1, L2)

The service graph template uses a specific device that is based on a device selection policy (called a logical device context) that an administrator defines.

An administrator can set up a maximum of two concrete devices in active-standby mode.

To set up a device cluster, you must perform the following tasks:

  1. Connect the concrete devices to the fabric.

  2. Configure the device cluster with the Cisco APIC.


Note

The Cisco APIC does not validate a duplicate IP address that is assigned to two device clusters. The Cisco APIC can provision the wrong device cluster when two device clusters have the same management IP address. If you have duplicate IP addresses for your device clusters, delete the IP address configuration on one of the devices and ensure there are no duplicate IP addresses that are provisioned for the management IP address configuration.

About Concrete Devices

A concrete device can be either physical or virtual. If the device is virtual, you must choose the controller (vCenter or SCVMM controller) and the virtual machine name. A concrete device has concrete interfaces. When a concrete device is added to a logical device, the concrete interfaces are mapped to the logical interfaces. During service graph template instantiation, VLANs are programmed on concrete interfaces that are based on their association with logical interfaces.

About Trunking

You can enable trunking for a Layer 4 to Layer 7 virtual ASA device, which uses trunk port groups to aggregate the traffic of endpoint groups. Without trunking, a virtual service device can have only 1 VLAN per interface and up to 10 service graphs. With trunking enabled, the virtual service device can have an unlimited number of service graphs.

For more information about trunk port groups, see the Cisco ACI Virtualization Guide.

About Layer 4 to Layer 7 Services Endpoint Groups

The Application Policy Infrastructure Controller (APIC) enables you to specify an endpoint group to be used for the graph connector during graph instantiation. This enables you to better troubleshoot the graph deployment. The APIC uses the Layer 4 to Layer 7 services endpoint group that you specified to download encapsulation information to a leaf switch. The APIC also uses the endpoint group to create port groups on the distributed virtual switch for virtual devices. A Layer 4 to Layer 7 services endpoint group is also used to aggregate faults and statistics information for a graph connector.

In addition to the enhanced visibility into the deployed graph resources, a Layer 4 to Layer 7 services endpoint group can also be used to specify static encapsulation to be used for a specific graph instance. This encapsulation can also be shared across multiple graph instances by sharing the Layer 4 to Layer 7 services endpoint group across multiple graph instances.

For example XML code that shows how you can use a Layer 4 to Layer 7 services endpoint group with a graph connector, see Example XML of Associating a Layer 4 to Layer 7 Service Endpoint Group with a Connector.

Using Static Encapsulation for a Graph Connector

The Application Policy Infrastructure Controller (APIC) allocates the encapsulation for various service graphs during processing. In some use cases, you want to be able explicitly to specify the encapsulation to be used for a specific connector in the service graph. This is known as static encapsulation. Static encapsulations are only supported for the service graph connector that has a service device cluster with physical services. Service device clusters with virtual service devices use the VLANs from the VMware or SCVMM domain that is associated with the service device cluster.

A static encapsulation can be used with a graph connector by specifying the encapsulation value as part of the Layer 4 to Layer 7 service endpoint group. For example XML code that shows how you can use a static encapsulation with a Layer 4 to Layer 7 services endpoint group, see Example XML of Using Static Encapsulation with a Layer 4 to Layer 7 Service Endpoint Group.

Configuring a Layer 4 to Layer 7 Services Device Using the GUI

When you create a Layer 4 to Layer 7 services device, you can connect to either a physical device or a virtual machine. The fields are slightly different depending on the type to which you are connecting. When you connect to a physical device, you specify the physical interface. When you connect to a virtual machine, you specify the VMM domain, the virtual machine, and the virtual interfaces. Additionally, you can select an unknown model, which allows you to configure the connections manually.

Before you begin

  • You must have configured a tenant.

Procedure

Step 1

On the menu bar, choose Tenants > All Tenants.

Step 2

In the Work pane, double click the tenant's name.

In the Work pane, choose Actions > Create L4-L7 Devices.

Step 5

In the Create L4-L7 Devices dialog box, in the General section, complete the following fields:

Name

Description

Name field

Enter a name for the device.

Service Type drop-down list

Choose the service type. The types are:

(Cisco ACI Virtual Edge only)

For a Cisco ACI Virtual Edge virtual domain, choose one of the following modes:

  • AVE: Traffic is switched through the Cisco ACI Virtual Edge.

  • native: Traffic is switched through the VMware DVS.

View radio buttons

Choose the view for the device. The view can be:

  • Single Node: Only one node

  • Cluster: 3 or more nodes

Context Aware

The context awareness of the device. The awareness can be:

  • Single: The device cluster cannot be shared across multiple tenants of a given type that are hosted on the provider network. You must give the device cluster to a specific tenant for a given user.

  • Multiple: The device cluster can be shared across multiple tenants of a given type that you are hosting on the provider network. For example, there could be two hosting companies that share the same device.

The default is Single.

Note

 

When you create a Layer 4 to Layer 7 services device that is a load balancer, the Context Aware parameter is not used and can be ignored. Beginning with the 5.2(1) release, this parameter is deprecated and the Cisco APIC ignores the value.

Function Type

Function types are:
