request mpls lsp adjust-autobandwidth


Syntax (EX and QFX Series Switches)


Manually trigger a bandwidth allocation adjustment for active label-switched paths (LSPs).

Without running this command, the bandwidth adjustment is recomputed at a configurable interval. The default interval is 5 minutes. If you do not want to wait for the periodic adjustment (for example, during a software demonstration), this command is useful.

During bandwidth allocation adjustment, the LSP stays up to enable the bandwidth to be changed without dropping any traffic. This functionality is often referred to as make-before-break.



Manually trigger a bandwidth allocation adjustment for all active LSP paths.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.

name lsp-name

(Optional) Manually trigger a bandwidth allocation adjustment on the specified LSP only.

Additional Information

For this command to work properly, the following conditions must exist:

  • Automatic bandwidth allocation must be enabled on the LSP. The parameters for adjustment interval and maximum average bandwidth are not reset after you issue the request mpls lsp adjust-autobandwidth command.

  • The difference between the adjusted bandwidth and the current LSP path bandwidth must be greater than the threshold limit.
