Field	Description
Local interface	Interface on the local router that has been enabled to send and receive Layer 2
	packets. The interface varies, depending on the transport type. The output also
	shows the status of the interface.
VC ID	VC identifier assigned to the interface on the router.
VC status	Status of the VC, which is one of the following:
	UP—The VC is in a state where it can carry traffic between the two VC
	endpoints. A VC is up when both imposition and disposition interfaces are
	programmed.
	• The disposition interface is programmed if the VC has been configured and
	the client interface is up.
	• The imposition interface is programmed if the disposition interface is
	programmed and a remote VC label and an IGP label exist. The IGP label
	can be an implicit null in a back-to-back configuration. (An IGP label
	means there is an LSP to the peer.)
	DOWN—The VC is not ready to carry traffic between the two VC endpoints.
	ADMIN DOWN—The VC has been disabled by a user.
Output interface	Interface on the remote router that has been enabled to transmit and receive
	Layer 2 packets.
imposed label stack	Summary of the MPLS label stack used to direct the VC to the PE router.
Preferred path	Path that was assigned to the VC and the status of that path. The path can be an
	MPLS traffic engineering tunnel or an IP address or hostname of a PE router.
Default path	Status of the default path, which can be disabled or active.
	By default, if the preferred path fails, the router uses the default path. However,
	you can disable the router from using the default path when the preferred path
	fails by specifying the disable-fallbackkeyword with the preferred-path
	command.
Create time	Time when the VC was provisioned.
last status change	Last time the VC state changed.
time
Signaling protocol	Type of protocol used to send the MPLS labels. The output also shows the status
	of the peer router.
MPLS VC labels	Local VC label is a disposition label, which determines the egress interface of
	an arriving packet from the MPLS backbone. The remote VC label is a
	disposition VC label of the remote peer router.
Group ID	Local group ID is used to group VCs locally. The remote group ID is used by
	the peer to group several VCs.
MTU	Maximum transmission unit specified for the local and remote interfaces.
Remote interface	Interface on the remote router that has been enabled to transmit and receive
description	Layer 2 packets.
Sequencing	Indicates whether sequencing of out-of-order packets is enabled or disabled.
