Table 76 show tag-switching atm-tdp capability Field Descriptions 

Field	Description
VPI Range	Minimum and maximum number of VPIs supported on this interface.
VCI Range	Minimum and maximum number of VCIs supported on this interface.
Alloc Scheme	UNIDIR—Unidirectional capability indicates that the peer device can, within a single VPI, support binding of the same VCI to different prefixes on different directions of the link. BIDIR—Bidirectional capability indicates that within a single VPI, a single VCI can appear in one binding only. In this case, one peer device allocates bindings in the even VCI space, and the other in the odd VCI space. The system with the lower LDP identifier will assign even-numbered VCIs. The negotiated allocation scheme is UNIDIR, if and only if, both peer devices have UNIDIR capability. Otherwise it is BIDIR.
Odd/Even Scheme	Indicates whether the local device or the peer device is assigning an odd- or even-numbered VCI when the negotiated scheme is BIDIR. It does not display any information when the negotiated scheme is UNIDIR.
VC Merge	Indicates the type of VC merge support on this interface. IN—Indicates input interface merge capability. IN accepts the following values: •EN—The hardware interface supports VC merge and VC merge is enabled on the device. •DIS—The hardware interface supports VC merge and VC merge is disabled on the device. •NO—The hardware interface does not support VC merge. OUT—Indicates output interface merge capability. OUT accepts the same values as the input merge side. The VC merge capability is meaningful only on ATM switches. It is not negotiated.
Negotiated	Set of options that both LDP peer devices have agreed to share on this interface. For example, the VPI or VCI allocation on either peer device remains within the negotiated ranges.
Local	Options supported locally on this interface.
Peer	Options supported by the remote LDP peer device on this interface.

Table 82 show tag-switching tdp bindings Field Descriptions 

Field	Description
tib entry	Indicates that the following lines are the LIB (TIB) entry for a particular destination (network/mask). The revision number is used internally to manage label distribution for this destination.
remote binding	A list of outgoing labels for this destination learned from other Label Switching Routers (LSRs). Each item on this list identifies the LSR from which the outgoing label was learned and the label itself. The LSR is identified by its LDP identifier.
imp-null	The implicit null label. This label value instructs the upstream router to pop the label entry off the label stack before forwarding the packet.
