monitor mpls loss rsvp

Syntax

Description

Perform an on-demand loss measurement and display the measured values for associated bidirectional MPLS ultimate hop popping (UHP) point-to-point label-switched paths (LSPs).

Options

lsp-name

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

detail

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

bytes

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

Note:

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 loss measurements to be carried out for the MPLS UHP LSP. For LSP loss measurement, the number of queries sent is the specified count number plus one additional query, because the LSP loss 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

traffic-class traffic-class

(Optional) Specify the traffic class and enable traffic-class-statistics for the LSP loss measurement.

  • Range: 0 though 7

Field Name

Field Description

Level of Output

Current forward loss

Difference between the current forward transmit count and the current forward receive count.

All Levels

Current forward loss ratio

Total packet loss (current forward loss divided by current forward transmit count).

All Levels

Current forward throughput

Current forward transmit count divided by 1000.

All Levels

Current reverse loss

Difference between the current reverse transmit count and the current reverse receive count.

All Levels

Current reverse loss ratio

Total packet loss (current reverse loss divided by current reverse transmit count).

All Levels

Current reverse throughput

Current reverse transmit count divided by 1000.

All Levels

Cumulative forward transmit count

Cumulative forward transmit counter value at the time the loss measurement message was originated.

All Levels

Cumulative forward loss

Cumulative forward loss counter value at the time the loss measurement message was originated.

All Levels

Average forward loss ratio

Average packet loss (current forward loss divided by current forward transmit count).

All Levels

Average forward throughput

Average forward transmit count divided by 1000.

All Levels

Cumulative reverse transmit count

Cumulative reverse transmit counter value at the time the loss measurement message was originated.

All Levels

Cumulative reverse loss

Difference between the cumulative reverse transmit count and the cumulative reverse receive count.

All Levels

Average reverse loss ratio

Average packet loss (average reverse loss divided by average reverse transmit count).

All Levels

Average reverse throughput

Average reverse transmit count divided by 1000.

All Levels

LM queries sent

Number of queries sent for loss measurement.

All Levels

LM responses received

Number of responses received for loss measurement queries.

All Levels

LM queries timedout

Number of timed out queries sent for loss measurement.

All Levels

All Levels

Response code

Status of the messages used for loss measurement. Response code can be one of the following:

  • Success—Successful response code.

  • Failed—Failed response code.

detail

Origin timestamp

Time and date the loss measurement message is originated without any specific format (NTP and PTP).

detail

Forward transmit count

Forward transmit counter value at the time the loss measurement message was originated.

detail

Forward receive count

Forward receive counter value at the time the loss measurement message was originated.

detail

Reverse transmit count

Reverse transmit counter value at the time the loss measurement message was originated.

detail

Reverse receive count

Reverse receive counter value at the time the loss measurement message was originated.

detail

Current forward transmit count

Difference between the current forward transit count and the previous forward transit count.

detail

Current forward receive count

Difference between the current forward receive count and the previous forward receive count.

detail

Current reverse transmit count

Difference between the current reverse transit count and the previous reverse transit count.

detail

Current reverse receive count

Difference between the current reverse receive count and the previous reverse receive count.
