Associating Service Graph Templates with Contracts and EPGs Using the GUI

See Using the GUI for the procedure for associating service graph templates with contracts and EPGs.

Creating a Service Graph Template Using the NX-OS-Style CLI

The following procedure creates a service graph template.

Procedure

Step 1

Enter the configure mode.

Example:

apic1# configure

Step 2

Enter the configure mode for a tenant.

tenant tenant_name

Example:

apic1(config)# tenant t1

Step 3

Associate a service graph to the template.

l4l7 graph graph_name contract contract_name


Parameter	Description
graph	The name of the service graph template.
contract	The name of the contract to use with the service graph template.

Example:

apic1(config-tenant)# l4l7 graph GraphL3asa contract ContractL3ASA

Step 4

Add a function node.

service node_name [device-cluster-tenant tenant_name] [device-cluster device_name] [mode deployment_mode]


Parameter	Description
service	The name of the service node to add.
device-cluster-tenant	The tenant from which to import the device cluster. Specify this only if the device-cluster is not in the same tenant in which the graph is being configured.
device-cluster	Name of the device cluster to use for this service node.
mode	The deployment mode. Possible values are: ADC_ONE_ARM—Specifies one-arm mode. ADC_TWO_ARM—Specifies two-arm mode. FW_ROUTED—Specifies routed (GoTo) mode. FW_TRANS—Specifies transparent (GoThrough) mode. OTHERS If the mode is not specified, then a deployment mode is not used.

Example:

apic1(config-graph)# service Node1 device-cluster-tenant common device-cluster ifav108-asa-2 mode FW_ROUTED

Step 5

Add the consumer connector.

connector connector_type [cluster-interface interface_type]


Parameter	Description
connector	The type of the connector in the service graph. Possible values are: provider consumer
cluster-interface	The type of the device cluster interface. Possible values are: provider consumer Do not specify this parameter if you are a service graph template in tenant `Common`.

Example:

apic1(config-service)# connector consumer cluster-interface consumer

Step 6

Associate a tenant with the connector and then exit the connector configuration mode.

l4l7-peer tenant tenant_name out L3OutExternal epg epg_name
  redistribute redistribute_property
exit


Parameter	Description
tenant	The name of the tenant to associate with the connector.
out	The name of the Layer 3 outside.
epg	The name of the endpoint group.
redistribute	The properties of the redistribute protocol.

Example:

apic1(config-connector)# l4l7-peer tenant t1 out L3OutExternal epg L3ExtNet
  redistribute connected,ospf
apic1(config-connector)# exit

Step 7

Repeat steps 5 and 6 for the provider.

Example:

apic1(config-service)# connector provider cluster-interface provider
apic1(config-connector)# l4l7-peer tenant t1 out L3OutInternal epg L3IntNet
  redistribute connected,ospf
apic1(config-connector)# exit

Step 8

(Optional) Add a router and then exit the node configuration mode.

rtr-cfg router_ID
exit


Parameter	Description
rtr-cfg	The ID of the router.

Skip this step if you are creating a service graph template in tenant Common.

Example:

apic1(config-service)# rtr-cfg router-id1
apic1(config-service)# exit

Step 9

Associate a connection with a consumer connector and another with a provider connector, and then exit the service graph configuration mode.

connection connection_name terminal terminal_type service node_name
  connector connector_type
exit


Parameter	Description
connection	The name of the connection to associate with the connector.
terminal	The type of the terminal. Possible values are: provider consumer
service	The name of the node of the service graph.
connector	The type of the connector. Possible values are: provider consumer

Example:

apic1(config-graph)# connection C1 terminal consumer service Node1 connector consumer
apic1(config-graph)# connection C2 terminal provider service Node1 connector provider
apic1(config-graph)# exit

Step 10

Exit the configuration mode.

Example:

apic1(config-tenant)# exit
apic1(config)# exit

Configuring a Service Graph Template Using the REST APIs

You can configure a service graph template using the following REST API:

<polUni>
    <fvTenant dn="uni/tn-acme" name="acme">
      <!—L3 Network-->
      <fvCtx name="MyNetwork"/>
        <!-- Bridge Domain for MySrvr EPG -->
        <fvBD name="MySrvrBD">
           <fvRsCtx tnFvCtxName="MyNetwork" />
           <fvSubnet ip="10.10.10.10/24">
           </fvSubnet>
        </fvBD>
        <!-- Bridge Domain for MyClnt EPG -->
        <fvBD name="MyClntBD">
          <fvRsCtx tnFvCtxName="MyNetwork" />
          <fvSubnet ip="20.20.20.20/24">
          </fvSubnet>
        </fvBD>
        <fvAp dn="uni/tn-acme/ap-MyAP" name="MyAP">
            <fvAEPg dn="uni/tn-acme/ap-MyAP/epg-MyClnt" name="MyClnt">
                <fvRsBd tnFvBDName="MySrvrBD" />
                <fvRsDomAtt tDn="uni/vmmp-Vendor1/dom-MyVMs" />
                <fvRsProv tnVzBrCPName="webCtrct">
                </fvRsProv>
                <fvRsPathAtt tDn="topology/pod-1/paths-17/pathep-[eth1/21]" encap="vlan-202"/>
                <fvRsPathAtt tDn="topology/pod-1/paths-18/pathep-[eth1/21]" encap="vlan-202"/>
            </fvAEPg>
            <fvAEPg dn="uni/tn-acme/ap-MyAP/epg-MySRVR" name="MySRVR">
                <fvRsBd tnFvBDName="MyClntBD" />
                <fvRsDomAtt tDn="uni/vmmp-Vendor1/dom-MyVMs" />
                <fvRsCons tnVzBrCPName="webCtrct">
                </fvRsCons>
                <fvRsPathAtt tDn="topology/pod-1/paths-17/pathep-[eth1/21]" encap="vlan-203"/>
                <fvRsPathAtt tDn="topology/pod-1/paths-18/pathep-[eth1/21]" encap="vlan-203"/>
            </fvAEPg>
        </fvAp>
    </fvTenant>
</polUni>

Creating a Security Policy Using the REST APIs

You can create a security policy using the following REST API:

<polUni>
    <fvTenant dn="uni/tn-acme" name="acme">
        <vzFilter name="HttpIn">
            <vzEntry name="e1" prot="6" dToPort="80"/>
      		</vzFilter>
        <vzBrCP name="webCtrct">
            <vzSubj name="http">
                <vzRsSubjFiltAtt tnVzFilterName="HttpIn"/>
            </vzSubj>
        </vzBrCP>
    </fvTenant>
</polUni>
