monitor mpls loss-delay rsvp



Perform a simultaneous on-demand loss and delay measurement using combined loss and delay messages, and display the measured values for associated bidirectional MPLS ultimate hop popping (UHP) point-to-point label-switched paths (LSPs).



Name of the associated bidirectional MPLS UHP LSP for which the delay measurement is performed.


(Optional) Display detailed output of the LSP delay measurement.


(Optional) Specify the measurement quantity for the LSP loss measurement as bytes. By default, LSP loss is measured in packets.


The byte count of a packet sent or received over a channel counts only the payload, including the total length of that packet and excluding the headers, labels, and framing of the channel itself.

count count

(Optional) Specify the number of delay measurements to be carried out for the MPLS UHP LSP. For LSP delay measurement, the number of queries sent is the specified count number plus one additional query, because the LSP delay is measured using successive messages.

  • Default: 10

  • Range: 1 through 1000000

interval seconds

(Optional) Specify in seconds the interval between two successive query messages.

  • Range: 1 through 255 seconds

padding-size padding-size

(Optional) Specify the length of padding TLV to be included in the query message.

  • Range: 0 through 1500

traffic-class traffic-class

(Optional) Specify the traffic class for the LSP delay measurement. When the traffic-class value is not specified, the default traffic-class code-point of 111 is used.

  • Range: 0 though 7
