	Field	Description
	Tunnel label	An IGP label used to route the packet over the MPLS backbone to the
		destination router with the egress interface. The first part of the output displays
		the type of label. The second part of output displays the route information.
		The tunnel label information can display any of the following states:
		• imp-null—The provider (P) router is absent and the tunnel label is not to be
			used. Alternatively, imp-null can signify traffic engineering tunnels
			between the PE routers.
		• unassigned—The label has not been assigned.
		• no route—The label is not in the routing table.
		• no adjacency—The adjacency for the next hop is missing.
		• not ready, no route—An IP route for the peer does not exist in the routing
			table.
		• not ready, not a host table—The route in the routing table for the remote
			peer router is not a host route.
		• not ready, Cisco Express Forwarding disabled—Cisco Express Forwarding
			is disabled.
		• not ready, LFIB disabled—The MPLS switching subsystem is disabled.
		• not ready, label forwarding information base (LFIB) entry present—The
			tunnel label exists in the LFIB, but the VC is down.
	SSO Descriptor	Identifies the VC for which the information was checkpointed.
	local label	The value of the local label that was checkpointed (that is, sent on the active
		Route Processor [RP], and received on the standby RP).
	SSM	The IDs used to refer to the control plane and data plane contexts for this VC.
	segment/switch IDs	This data is not for customer use but for Cisco personnel for troubleshooting
		purposes. When the source specific multicast (SSM) IDs are followed by the
		word "used," the checkpointed data has been successfully sent and not released.
	PWID	The PW ID used in the data plane to correlate the switching context for the
		segment mentioned with the MPLS switching context. This data is not for
		customer use but for Cisco personnel for troubleshooting purposes.
	packet totals	Number of packets sent and received. Received packets are those AToM packets
		received from the MPLS core. Sent packets are those AToM packets sent to the
		MPLS core. This does not include dropped packets.
	byte totals	Number of bytes sent and received from the core-facing interface, including the
		payload, control word if present, and AToM VC label.
	packet drops	Number of dropped packets.
