Configuring Passive Bandwidth Utilization Monitoring

Use the monitor-bandwidth statement to switch to a passive bandwidth utilization monitoring mode. In this mode, no automatic bandwidth adjustments are made, but the maximum average bandwidth utilization is continuously monitored and recorded.

To configure passive bandwidth utilization monitoring, include the monitor-bandwidth statement:

monitor-bandwidth;

You can include this statement at the following hierarchy levels:

• [edit protocols mpls label-switched-path lsp-name auto-bandwidth]
• [edit logical-routers logical-router-name protocols mpls label-switched-path lsp-name auto-bandwidth]

If you have configured an LSP with primary and secondary paths, the automatic bandwidth allocation statistics are carried over to the secondary path if the primary path fails. For example, consider a primary path whose adjustment interval is half complete and whose maximum average bandwidth usage is currently calculated as 50 Mbps. If the primary path suddenly fails, the time remaining for the next adjustment and the maximum average bandwidth usage are carried over to the secondary path.
