Display automatic bandwidth information for the LSP(s).
After a Routing Engine switchover, the output of the show mpls autobandwidth command might not be up-to-date, as the automatic bandwidth information for the LSP(s) is gathered by the new master Routing Engine during the first adjustment interval.

Table 1 describes the output fields for the show mpls lsp autobandwidth command. Output fields are listed in the approximate order in which they appear.
Table 1: show mpls lsp autobandwidth Output Fields
Level of Output
Destination (egress routing device) of the session.
Source (ingress routing device) of the session.
Name of the LSP.
(Ingress LSP) Configured minimum value of the LSP, in bps.
(Ingress LSP) Configured maximum value of the LSP, in bps.
Max AvgBW util
(Ingress LSP) Current value of the actual maximum average bandwidth utilization, in bps.
Note: In calculating this value, the sample collected during make before break (MBB) is ignored to prevent inaccurate results. The first sample after a bandwidth adjustment, or after a change in the LSP ID (regardless of path change), is also ignored.
(Ingress LSP) Configured value of the threshold overflow limit.
Overflow sample count
(Ingress LSP) Current value for the overflow sample count.
(Ingress LSP) Configured value of the threshold underflow limit.
Underflow sample count
(Ingress LSP) Current value for the underflow sample count.
(Ingress LSP) Configured value for the adjust-timer statement, indicating the total amount of time allowed before bandwidth adjustment will take place, in seconds.
(Ingress LSP) Configured value for the adjust-threshold statement. Specifies how sensitive the automatic bandwidth adjustment for an LSP is to changes in bandwidth utilization.
Time for Next Adjustment
(Ingress LSP) Time in seconds until the next automatic bandwidth adjustment sample is taken.
Time of Last Adjustment
(Ingress LSP) Date and time since the last automatic bandwidth adjustment was completed.
Previous active bandwidth of the LSP.
Last Requested BW
Bandwidth requested in the previous automatic bandwidth adjustment.
Last Signaled BW
Bandwidth signaled in the previous automatic bandwidth adjustment.
Highest Watermark BW
Maximum bandwidth used by the LSP.
Total AutoBw Adjustments
Total number of attempts to adjust automatic bandwidth including failed and successful adjustments.
Number of successful automatic bandwidth adjustments.
Number of failed automatic bandwidth adjustments.
