Description

Display automatic bandwidth information for the LSP(s).

After a Routing Engine switchover, the output of the show mpls autobandwidth command might not be up-to-date, as the automatic bandwidth information for the LSP(s) is gathered by the new master Routing Engine during the first adjustment interval.

Options

brief | detail | extensive (Optional) Display the specified level of output. The extensive option displays the same information as the detail option, but covers the most recent 50 events.
logical-system (all | logical-system-name)(Optional) Perform this operation on all logical systems or on a particular logical system.
name lsp-name(Optional) Specify name of the LSP for which the automatic bandwidth information should be displayed.

Level of Output

To

Destination (egress routing device) of the session.

All Levels

From

Source (ingress routing device) of the session.

All Levels

LSPname

Name of the LSP.

All Levels

Min BW

(Ingress LSP) Configured minimum value of the LSP, in bps.

detail extensive

Max BW

(Ingress LSP) Configured maximum value of the LSP, in bps.

detail extensive

Max AvgBW util

(Ingress LSP) Current value of the actual maximum average bandwidth utilization, in bps.

Note: In calculating this value, the sample collected during make before break (MBB) is ignored to prevent inaccurate results. The first sample after a bandwidth adjustment, or after a change in the LSP ID (regardless of path change), is also ignored.

detail extensive

Time of Last Adjustment

(Ingress LSP) Date and time since the last automatic bandwidth adjustment was completed.

detail extensive

Last BW

Previous active bandwidth of the LSP.

detail extensive

Last Requested BW

Bandwidth requested in the previous automatic bandwidth adjustment.

detail extensive

Last Signaled BW
