TABLE 5
Global -level auto-bandwidth commands
Command
Description
Enabling auto-bandwidth globally
The auto-bandwidth parameters can be pre-configured on an LSP at
the LSP level. To globally enable automatic bandwidth, use the
following commands.
Brocade(config)# router mpls
Brocade(config-mpls)# policy
Brocade(config-mpls-policy)# auto-bandwidth
sample-interval 30
Configuring sample intervals
Syntax: [no] auto-bandwidth [sample-interval value]
The sample-interval parameter specifies the time after which the
traffic rate is sampled.
The value parameter specifies the time interval after which the LSP
bandwidth must be adjusted.The range is from 60 through 604800
seconds (one week). The default value is 300 seconds.
Configurable parameters:
Parameter
Description
Adjustment-interval
Displays the configured adjustment-timer value.
Adjustment-threshold
Displays the configured adjustment-threshold value.
Percentage-based
Syntax: [no] adjustment-threshold value
The value parameter specifies the bandwidth is adjusted when the
percentage difference in old and new bandwidth is greater than or
equal to the specified adjust-threshold percentage, the LSPs
bandwidth is adjusted to the current bandwidth demand. The range
is from zero through 100 percent. The default value is zero percent.
Absolute table based
Syntax: [no] overflow limit value
The value parameter specifies the least number of times the
sampled bandwidth must consecutively overflow the adjustment
threshold to trigger premature adjustment. The range is from zero
through 65535 (where zero means it never adjusts for limit
overflow). The default value is zero.
Overflow-limit
Displays the configured overflow-limit value.
Underflow-limit
The number of sample which have to be below the threshold to
trigger a premature adjustment.
Minimum bandwidth
The configured minimum bandwidth.
Maximum bandwidth
The configured maximum bandwidth.
Mode
Mode will tell is the LSP is in monitor-only or monitor-and-signal
mode.
Executable commands:
Command
Description
Clearing auto-bandwidth statistics
To clear statistics for auto-bandwidth-enabled LSPs, enter the
following command.
Brocade(config-mpls-lsp-xyz-auto-bandwidth)#
clear mpls auto-bandwidth-statistics lsp xyz
