Field Description
Local intf The interface on the local router that has been enabled to transport Layer 2
pa
ckets.
Local circuit The type and number (if applicable) of the local circuit. The output shown in
t
his column varies, depending on the transport type:
• For Frame Relay, the output shows the DLCI of the PVC.
• For ATM cell relay and AAL5, the output shows the VPI or VCI of the
PVC.
• For Ethernet VLANs, the output shows the VLAN number.
• For PPP and High-Level Data Link Control (HDLC), the output shows the
interface number.
Dest address The IP address of the remote router’s interface that is the other end of the VC.
VC ID The virtual circuit identifier assigned to one of the interfaces on the router.
Status The status of the VC. The status can be one of the following:
• ADMIN DOWN—The VC has been disabled by a user.
• 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.
• HOTSTANDBY—The active pseudowire on a standby route processor.
• RECOVERING—The VC is recovering from a stateful switchover.
• STANDBY—The VC is designated as the backup circuit in a stateful
switchover configuration.
• 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.
