show mpls l2transport vc
The following example shows information about the NSF/SSO and graceful restart capability. The SSO
portion indicates when checkpointing data has either been sent (on active) or received (on standby).
When SSO data has not been successfully sent or has been released, the SSO information is not shown.

describes the significant fields shown in the display.
Status
The status of the VC. The status can be 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 you have a remote VC label and an Interior Gateway
Protocol (IGP) label. The IGP label can be implicit null in a back-to-back
configuration. An IGP label means there is a Label Switched Path (LSP)
to the peer.
•
DOWN—The VC is not ready to carry traffic between the two VC endpoints.
Use the detail keyword to determine the reason that the VC is down.
•
ADMIN DOWN—The VC has been disabled by a user.
•
RECOVERING—The VC is recovering from a stateful switchover.
