Verifying a DME Configuration

The following table contains the distinguished name (DN) for each managed object (MO) in the DME payload. Issue a GET request using the DN to verify the configuration was posted or to get information about the configured properties of a particular object.

MO	DN
interfaceEntity	sys/intf
natDom	sys/nat/inst/dom-default
natEntity	sys/nat
natInst	sys/nat/inst
sviIf	sys/intf/svi-[vlan1]

natDom Properties

The following table contains information about the natDom properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
name	naming:Name256 string:Basic	The name of the object.	RANGE: Min: "1" Max: "128"

natIf Properties

The following table contains information about the natIf properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
id	nw:IfId (base:IfIndex)	An identifier .	Must match first field in the output of `show intf brief`. Example: Eth1/1 or Vlan100
natIf	nat:NatTrafficDir (scalar:Enum8)	NAT interface config inside/outside	SELECTION: 0 - ip-nat-invalid 1 - ip-nat-inside 2 - ip-nat-outside

sviIf Properties

The following table contains information about the sviIf properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
id	nw:IfId (base:IfIndex)	An identifier .	Must match first field in the output of `show intf brief`. Example: Eth1/1 or Vlan100
