Juniper ACX2000 Configuration Guide

To specify the bandwidth reallocation interval in seconds for a specific LSP, include the
adjust-interval statement:
adjust-interval seconds;
You can include this statement at the following hierarchy levels:
•
[edit protocols mpls label-switched-path lsp-name auto-bandwidth (MPLS Tunnel)]
•
[edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name
auto-bandwidth (MPLS Tunnel)]
Configuring the Maximum and Minimum Bounds of the LSP’s Bandwidth
You can maintain the LSP’s bandwidth between minimum and maximum bounds by
specifying values for the minimum-bandwidth and maximum-bandwidth statements.
To specify the minimum amount of bandwidth allocated for a specific LSP, include the
minimum-bandwidth statement:
minimum-bandwidth bps;
You can include this statement at the following hierarchy levels:
•
[edit protocols mpls label-switched-path lsp-name auto-bandwidth (MPLS Tunnel)]
•
[edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name
auto-bandwidth (MPLS Tunnel)]
To specify the maximum amount of bandwidth allocated for a specific LSP, include the
maximum-bandwidth statement:
maximum-bandwidth bps;
You can include this statement at the following hierarchy levels:
•
[edit protocols mpls label-switched-path lsp-name auto-bandwidth (MPLS Tunnel)]
•
[edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name
auto-bandwidth (MPLS Tunnel)]
Configuring the Automatic Bandwidth Adjustment Threshold
Use the adjust-threshold statement to specify the sensitivity of the automatic bandwidth
adjustment of an LSP to changes in bandwidth utilization. You can set the threshold for
when to trigger automatic bandwidth adjustments. When configured, bandwidth demand
for the current interval is determined and compared to the LSP’s current bandwidth
allocation. If the percentage difference in bandwidth is greater than or equal to the
specified adjust-threshold percentage, the LSP’s bandwidth is adjusted to the current
bandwidth demand.
For example, assume that the current bandwidth allocation is 100 megabits per second
(Mbps) and that the percentage configured for the adjust-threshold statement is 15
percent. If the bandwidth demand increases to 110 Mbps, the bandwidth allocation is not
adjusted. However, if the bandwidth demand increases to 120 Mbps (20 percent over
