an immediate bandwidth adjustment.
To use the
request mpls lsp adjust-autobandwidth
Automatic bandwidth allocation must be enabled on the LSP.
The criteria required to trigger a bandwidth adjustment have been met (the difference
between the adjust bandwidth and the current LSP path bandwidth is greater than
the threshold limit).
A manually triggered bandwidth adjustment operates only on the active LSP path. Also,
if you have enabled periodic automatic bandwidth adjustment, the periodic automatic
bandwidth adjustment parameters (the adjustment interval and the maximum average
bandwidth) are not reset after a manual adjustment.
For example, suppose the periodic adjust interval is 10 hours and there are currently
5 hours remaining before an automatic bandwidth adjustment is triggered. If you initiate
a manual adjustment with the
adjust timer is not reset and still has 5 hours remaining.
To manually trigger a bandwidth allocation adjustment, you need to use the
lsp adjust-autobandwidth
on the router, or you can specify a particular LSP:
user@host> request mpls lsp adjust-autobandwidth
Once you execute this command, the automatic bandwidth adjustment validation process
is triggered. If all the criteria for adjustment are met, the LSP's active path bandwidth is
adjusted to the adjusted bandwidth value determined during the validation process.
Release Description

value bandwidth samples are considered as underflow samples, except for the
zero value samples that arrive after an LSP comes up for the first time, and the
zero value samples that arrive first after a Routing Engine switchover.
