Auto-bandwidth for RSVP LSPs
1
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.
The [no] option sets the corresponding parameter value to the default.
Configuring the monitoring mode
The mode command can be either monitor-and-signal or monitor-only. When the mode is set to
monitor-only, LSPs bandwidth adjustments are disabled, but the maximum average bandwidth is
continuously monitored. The auto-bandwidth session only gathers and displays the relevant
information. The default mode is monitor-and-signal.
Brocade(config-mpls-lsp-xyz)# auto-bandwidth
Brocade(config-mpls-lsp-xyz-auto-bandwidth)# mode monitor-only
Syntax: [no] mode monitor-only | monitor-and-signal
The [no] option sets the corresponding parameter value to the default.
Manually triggered bandwidth allocation adjustments
For manually triggered bandwidth allocation adjustments, the minimum value for the adjustment
interval is five (5) minutes (300 seconds). It might be necessary to trigger a bandwidth allocation
adjustment manually.
A manually triggered bandwidth adjustment operates only on the active LSP. When the user
enables periodic automatic bandwidth adjustments, the periodic automatic bandwidth adjustment
parameters are not reset after a manual adjustment.
Once the user executes the mpls adjust-bandwidth command, the automatic bandwidth
adjustment validation process is triggered. The conditions to be met for successful manual
adjustment are that at least one sample must have been collected and the maximum of samples
collected must cross the threshold. This must be executed in the monitor-and-signal mode. Once all
the criteria for adjustment are met, the LSPs active path bandwidth is adjusted to the maximum of
the rate samples collected so far in the current adjustment-interval.
Brocade(config-mpls-lsp-xyz)# auto-bandwidth
Brocade(config-mpls-lsp-xyz-auto-bandwidth)# mpls adjust-bandwidth lsp xyz
Syntax: mpls adjust-bandwidth lsp lsp_name
The lsp lsp_name parameter adjusts the bandwidth for the named LSP.
