mpls te auto-bandwidth
Use mpls te auto-bandwidth to enable automatic bandwidth adjustment or output rate collection for an
MPLS TE tunnel.
Use undo mpls te auto-bandwidth to disable automatic bandwidth adjustment and output rate collection
for an MPLS TE tunnel.
Syntax
mpls te auto-bandwidth { adjustment [ frequency seconds ] [ max-bw max-bandwidth | min-bw
min-bandwidth ] * | collect-bw [ frequency seconds ] }
undo mpls te auto-bandwidth
Default
Automatic bandwidth adjustment and output rate collection are disabled for an MPLS TE tunnel.

Parameters
adjustment: Enables automatic bandwidth adjustment for the tunnel.
collect-bw: Enables output rate collection for the tunnel, but does not adjust the tunnel's bandwidth.
frequency seconds: Specifies the automatic bandwidth adjustment interval (with the adjustment keyword)
or the output rate collection interval (with the collect-bw keyword). The value range for the seconds
argument is 300 to 604800, in seconds. The default interval is 86400 seconds (24 hours).
max-bw max-bandwidth: Specifies the maximum automatic bandwidth for the tunnel, in the range of 1
to 4294967295, in kbps. If you do not specify this option, TE does not limit the maximum bandwidth
value.
min-bw min-bandwidth: Specifies the minimum automatic bandwidth for the tunnel, in the range of 1 to
4294967295, in kbps. If you do not specify this option, TE does not limit the minimum bandwidth value.
Usage guidelines
Automatic bandwidth adjustment functions as follows:
1. Samples the tunnel interface output rate at regular intervals.
The sampling interval is specified by using the auto-bandwidth enable command.
2. Calculates the average output rate in each sampling interval.
3. Adjusts the MPLS TE tunnel bandwidth to the maximum average output rate when the automatic
bandwidth adjustment interval is reached.
The maximum average output rate refers to the largest of all average output rates calculated in the
sampling intervals during the automatic bandwidth adjustment interval. HP recommends that you
