Description

Display Multiprotocol Label Switching (MPLS) Constrained Shortest Path First (CSPF) statistics.

Options

none

Display MPLS CSFP statistics.

Output Fields

Table 1 describes the output fields for the show mpls cspf command. Output fields are listed in the approximate order in which they appear.

Table 1: show mpls cspf Output Fields

Field Name

Field Description

Queue length

Number of LSPs queued for automatic path computation.

current

Current queue length.

maximum

Maximum queue length (high-water mark).

dequeued

Number of terminated computation attempts.

Paths

Counters for label-switched path computations.

total

Sum of the next four fields.

successful

Number of path computations that were successfully completed.

no route

Number of path computations that failed because the destination is unreachable.

Sys Error

Number of path computations that failed because of lack of memory.

CSPFs

Total number of CSPF computations. A single path might require multiple CSPF computations.

Time

Time, in seconds, required to perform the label-switched path computation.

Total

Total amount of time consumed by the CSPF path computation algorithm.

CSPFs

Total number of CSPF computations.

Avg per CSPF

Average amount of time required for each CSPF computation.

% of rpd
