auto-bw (LSP Attributes)
To specify automatic bandwidth configuration for a label switched path (LSP) in an LSP attribute list,
use the auto-bw command in LSP Attributes configuration mode. To remove automatic bandwidth
configuration, use the no form of this command.
auto-bw [f
requency secs] [max-bw kbps] [min-bw kbps] [collect-bw]
no au
to-bw
Syntax Description
Command Default If the command is entered with no optional keywords, automatic bandwidth adjustment for the LSP is
en
abled, with adjustments made every 24 hours and with no constraints on the bandwidth adjustments
made.
If the co
llect-bw keyword is entered, the bandwidth is sampled but not adjusted, and the other options,
if any, are ignored.
If the co
llect-bw keyword is not entered and some, but not all of the other keywords are entered, the
defaults for the keywords not entered are: frequency, every 24 hours; min-bw, unconstrained (0);
max-bw, unconstrained.
Command Modes LSP Attributes configuration (config-lsp-attr)
Command History
Usage Guidelines Use this command to set an automatic bandwidth configuration in an LSP attributes list.
To sample the bandwidth used by an LSP without automatically adjusting it, specify the co
llect-bw
keyword in the auto-bw command in an LSP attribute list.
If you enter the aut
o-bw command without the collect-bw keyword, the bandwidth of the LSP is
adjusted to the largest average output rate sampled for the LSP since the last bandwidth adjustment for
the LSP was made.
frequency se
cs (Optional) Interval between bandwidth adjustments. The specified interval
can be from 300 to 604800 seconds.
max-bw kb
ps (Optional) Maximum automatic bandwidth for the path option. The value
can be from 0 to 4294967295 kilobits per second (kbps).
min-bw kb
ps (Optional) Minimum automatic bandwidth for the path option. The value is
from 0 to 4294967295 kilobits per second (kbps).
collect-bw (Optional) Collects output rate information for the path option, but does not
a
djust its bandwidth.
