NAME
       chain - Defines a service function chain in the Service Function
       Chaining (SFC) architecture.

MODULE
       net sfc

SYNTAX
       Define a SFC chain.

   CREATE
	create chain [name]
	  options:
	    app-service [[string] | none]
	    description [[string] | none]
	    hops
	      [add | delete ] {
		[name] ... {

DESCRIPTION
       You can use the net sfc chain to create a n ordered set of abstract
       service functions and ordering constraints that must be applied to
       packets and/or frames and/or flows selected as the result of
       classification.

       There is no modify for net sfc chain.  Any modification needs to be
       done by deleting the chain and then creating it.

EXAMPLES
       create net sfc chain SC

       Creates a service function chain named SC. (See below).

       list net sfc chain SC all-properties

       Displays all of the properties of a service function chain.

       delete net sfc chain

       Deletes a service function chain (see below).

       Example :

       list net sfc chain chain1 net sfc chain chain1 {
	   hops {
	       1 {
		   nexthop-service sf2-1
		   service-index 255
	       }
	       2 {
		   nexthop-terminate
		   service-index 254
	       }
	   }
	   path-id 678 }

       app-service
	    Specifies the name of the application service to which the object
	    belongs. The default value is none. Note: If the strict-updates
	    option is enabled on the application service that owns the object,
	    you cannot modify or delete the object. Only the application
	    service can modify or delete the object.

       name Specifies a unique name for the chain. This option is required for
	    the commands create and delete.

       description
	    User defined description.

       hops The list of next-hops.

	    name      Specifies a unique name for the hop. This option is
		      required for the commands create and delete.

	    hopkey    Specifies the type of hop, service-index or interface.
		      The default is service-index.

	    nexthop-endpoint-ip
		      If nexthop-endpoint-ip is specified then it it assumed
		      the next hop is NSH enabled.  Only one of nexthop-
		      endpoint-ip, nexthop-service, nexthop-terminate may be
		      specified.

	    nexthop-service
		      The service function (SF) name of the next hop. Only one
		      of nexthop-endpoint-ip, nexthop-service, nexthop-
		      terminate may be specified.

	    nexthop-terminate
		      If nexthop-terminate is specified then the chain is
		      terminated and the NSH header is removed. Only one of
		      nexthop-endpoint-ip, nexthop-service, nexthop-terminate
		      may be specified.

	    service-index
		      The service-index is required when hopkey is service-
		      index.

	    source-interface
		      Specifics the interface name, a tunnel or vlan, to match
		      on ingress for this hop.	The source-interface is
		      required when hopkey is interface.

       path-id
	    The service path identifier that uniquely identifies the service
	    function path.
