Monitoring MPLS LSP Statistics

To display accounting information about LSPs, select Monitor>MPLS>LSP Statistics, or enter the following CLI command:

show mpls lsp statistics

Note: \Statistics are not available for LSPs on the outbound router, because the penultimate router in the LSP sets the label to 0. Also, as the packet arrives at the outbound router, the hardware removes its MPLS header and the packet reverts to being an IPv4 packet. Therefore, it is counted as an IPv4 packet, not an MPLS packet.

Table 66 summarizes key output fields in the MPLS LSP statistics display.

Table 66: Summary of Key MPLS LSP Statistics Output Fields

Field	Values	Additional Information
Ingress LSP	Information about LSPs on the inbound router. Each session has one line of output.
Egress LSP	Information about the LSPs on the outbound router. Each session has one line of output.	MPLS learns this information by querying RSVP, which holds all the transit and outbound session information.
Transit LSP	Number of LSPs on the transit routers and the state of these paths.	MPLS learns this information by querying RSVP, which holds all the transit and outbound session information.
To	Destination (outbound router) of the session.
From	Source (inbound router) of the session.
State	State of the path: Up, Down, or AdminDn.	AdminDn indicates that the LSP is being taken down gracefully.
Packets	Total number of packets received on the LSP from the upstream neighbor.
Bytes	Total number of bytes received on the LSP from the upstream neighbor.
LSPname	Configured name of the LSP.
Total	Total number of LSPs displayed for the particular type—ingress (inbound), egress (outbound), or transit.
