Auto-bandwidth for RSVP LSPs
1
Configuring auto-bandwidth feature at the global level
Auto-bandwidth is disabled by default. It is important that enabling auto-bandwidth globally is
necessary to have the auto-bandwidth session running on the LSP. 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
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.
The [no] option disables the auto-bandwidth globally. Auto-bandwidth is disabled from all the
auto-bandwidth-enabled LSPs.
Configuring per-LSP adjustment interval
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
Syntax: [no] adjustment-interval value
The value parameter specifies the time interval after which the LSP bandwidth must be adjusted.
The range is from 300 through 259200 seconds (30 days). The default value is 86400 seconds
(one day).
The [no] option disables the auto-bandwidth for the LSP. The bandwidth is set back to the
traffic-eng configured value immediately.
