sample interval. The maximum of this average data rate over multiple sample intervals is the
measured bandwidth input to the auto-bandwidth adjustment algorithms.
The adjust-multiplier is the number of collection intervals between periodic evaluations by the
ingress LER about whether to adjust the LSP bandwidth. The router keeps track of the maximum
average data rate of each LSP since the last reset of the adjust-count.
The adjust-multiplier is not allowed to be set to a value less than the sample-multiplier. It is
recommended that the adjust-multiplier be a multiple of the sample-multiplier.
The no form of this command instructs the system to take the value from the auto-bandwidth-defaults
command.
Default no multipliers
Parameters number1 — The number of collection intervals in a sample interval.
Values 1 — 511
Default inherited
number2 — The number of collection intervals in an adjust interval.
Values 1 — 16383

Description This command configures overflow-triggered auto-bandwidth adjustment. It sets the threshold at
which bandwidth adjustment is initiated due to the configured number of overflow samples having
been reached, regardless of how much time remains until the adjust interval ends.
A sample interval is counted as an overflow if the average data rate during the sample interval is
higher than the currently reserved bandwidth by at least the thresholds configured as part of this
command.
If overflow-triggered auto-bandwidth adjustment is successful the overflow count, maximum average
data rate and adjust count are reset. If overflow-triggered auto-bandwidth adjustment fails then the
overflow count is reset but the maximum average data rate and adjust count maintain current values.
This command is mutually exclusive with the monitor-bandwidth command.
The no form of this command disables overflow-triggered automatic bandwidth adjustment.
Default no overflow-limit
Parameters number — The number of overflow samples that triggers an overflow auto-bandwidth adjustment
attempt.
Values 1 — 10
Default 0 (disabled)
