Auto-bandwidth for RSVP LSPs
1
Template-based configuration
Template-based configuration provides a different way to configure the parameters. With this
method, the user can create a template of Auto-bandwidth values and apply it on the primary and
secondary paths.
To create a template, use the following commands:
Clearing auto-bandwidth sample history The auto-bandwidth history is deleted only in the cases when LSP is
itself deleted or when user clears or deletes the samples manually.
Clearing of auto bandwidth samples by user is recorded in the LSP
history.
Manual auto-bandwidth adjustment To specify the bandwidth reallocation interval in seconds for a
specific LSP, enter the following commands.
Brocade(config-mpls-lsp-xyz)# auto-bandwidth
Brocade(config-mpls-lsp-xyz-auto-bandwidth)#
mpls adjust-bandwidth lsp xyz
Direct configuration versus template-based
configuration There are two mechanisms of configuring LSP level parameters. The
direct configuration and template-based configuration. With these
mechanisms, there are inheritance and overriding behaviors for
various cases.
To specify the bandwidth reallocation interval in seconds for a
specific LSP, enter the following commands.
Brocade(config-mpls-lsp-xyz)# auto-bandwidth
Brocade(config-mpls-lsp-xyz-auto-bandwidth)#
adjustment-interval 86400
Overriding and Inheritance behavior When the user applies the template to an LSP, the LSP inherits the
values from the template. Because direct configuration is local to
the LSP, the user can override an inherited value using direct
configuration.
Show commands
Command Description
show mpls lsp detail The show mpls lsp detail command displays detailed information
about a specific LSP.
Syntax: show mpls lsp [detail ]
show mpls lsp extensive The show mpls lsp extensive command shows the adjustment event
with the previous rate and the maximum sampled rate.
Syntax: show mpls lsp [extensive]
show mpls lsp autobw-samples The samples obtained in an adjustment-interval can be displayed
whenever needed with the show command.
Syntax: show mpls lsp autobw-samples.
show mpls autobw-threshold-table This command displays the global-threshold table with the range of
current-bandwidth and the corresponding absolute
adjustment-threshold.
Syntax: show mpls autobw-threshold-table
show mpls autobw-template With this method, the user can create a template of auto-bandwidth
values and apply it on the primary and secondary paths.
Syntax: show mpls autobw-threshold-template
