Description
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 identifier assigned to the interface on the router.
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.
Interface on the remote router that has been enabled to transmit and receive
Layer 2 packets.
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.
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-fallback keyword with the preferred-path
command.
Time when the VC was provisioned.
Last time the VC state changed.
Type of protocol used to send the MPLS labels. The output also shows the status
of the peer router.
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.
Local group ID is used to group VCs locally. The remote group ID is used by
the peer to group several VCs.
Maximum transmission unit specified for the local and remote interfaces.
Interface on the remote router that has been enabled to transmit and receive
Layer 2 packets.
Indicates whether sequencing of out-of-order packets is enabled or disabled.
