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 on page 133 summarizes key output fields in the MPLS LSP statistics display.
