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
topSystem	sys
mplsldpLDP	sys/ldp
mplsldpSessProt	sys/ldp/sessprot

mplsldpLDP Properties

The following table contains information about the mplsldpLDP 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
adminSt	nw:AdminSt (scalar:Enum8)	The administrative state of the object or policy.	SELECTION: 1 - enabled 2 - disabled DEFAULT: enabled

mplsldpSessProt Properties

The following table contains information about the mplsldpSessProt 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
duration	mplsldp:ProtectDuration (scalar:Uint32)	The duration keyword enables you to specify how long the router should retain the LDP targeted hello adjacency following the loss of the LDP link hello adjacency. The range is from 30 to 2,147,483 seconds.	RANGE: [0 , 2147483]
infinite	scalar:Bool	The infinite keyword allows the LDP targeted hello adjacency to exist indefinitely following the loss of the LDP link hello adjacency.	SELECTION: true or false DEFAULT: false
pfxList	mplsldp:LdpPrefixListName (string:Basic)	Prefix list for LDP peers that should be protected. Session protection is then enabled for the peer routers in that prefix list	A sequence of characters
