Displays information about the status of the LDP sessions and hello adjacencies for all LDP peers.
| ipaddress | Display session and hello adjacency information for a single LDP peer. |
| detail | Display additional detailed information related to the session and adjacencies. |
N/A.
Specifying the LDP peer's ipaddress displays session and hello adjacency information for a single LDP peer. When the detail keyword is specified, additional detailed information related to the session and adjacencies is displayed.
show mpls label Field Definitions describes the display fields that appear when this command is entered.
| Field | Definition |
|---|---|
| IP Address | Local IP address, which is used as the LSR-ID. |
| LDP Peer | LDP identifier of LDP peer. |
| State | Displays the state of the Initialization State Machine as described in RFC 3036, LDP Specification. The states are: NonExistent, Initialized, OpenRec, OpenSent, and Operational. |
| Uptime | Displays the total time the session has been operational. |
| Adjacencies | Displays the number of active adjacencies with the LDP peer. |
| Index | The Entity Index used in the LDP Entity Table MIB. |
| Targeted Peer | The IP address of the peer used in Extended Discovery. If this is not a targeted peer (Basic Discovery was used), this field displays Not Targeted. |
| Attempted Sessions | This and other counters are described in RFC 3036, LDP Specification. |
| Shutdown Notifications | This and other counters are described in RFC 3036, LDP Specification. |
| Peer | IP address of peer. |
| Peer Label Space | The label space as given by the peer and derived from the LDP Identifier. A zero value represents the global or per-platform label space. A non-zero value represents a per interface label space. |
| Session State | Displays the state of the Initialization State Machine as described in RFC 3036, LDP Specification. The states are: NonExistent, Initialized, OpenRec, OpenSent, and Operational. |
| Session Uptime | Displays the total time the session has been operational. |
| Discontinuity Time | The system uptime for the most recent period after which one or more of the session's counters suffered a discontinuity. |
| Keep Alive Hold Timer | Displays the configured keep alive hold timer value and the remaining hold time. |
| Label Distribution Method | Label Distribution Method is either DU (Downstream Unsolicited) or DOD (Downstream On Demand), as described in RFC 3036, LDP Specification. |
| Max PDU Length | The maximum allowable length for LDP PDUs (Protocol Data Units) for this session. |
| Unknown Msg Type Errors | The number of messages received for this session without a recognized message type and without the ignore bit set. |
| Unknown TLV Errors | The number of TLVs received for this session without a recognized TLV type and without the ignore bit set. |
| Next Hop Addr(s) | A list of next hop addresses received from the peer through LDP address messages. |
