Usage Guidelines

Usage Scenario

The display mpls rsvp-te psb-content command can be run on a device to display information about the PSBs of the RSVP-TE tunnel that pass through the device. If no parameter is specified, the display mpls rsvp-te psb-content command displays information about all PSBs on the device.

Example

The actual command output varies according to the device. The command output here is only an example.
