Description

Perform an on-demand delay 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 delay measurement is performed.
detail	(Optional) Display detailed output of the LSP delay measurement.
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

Output Fields

Table 1 describes the output fields for the monitor mpls delay rsvp command. Output fields are listed in the approximate order in which they appear.

Table 1: monitor mpls delay rsvp Output Fields
Field Name	Field Description	Level of Output
Current two-way channel delay	Sum of packet delays, excluding the processing time of the remote provider edge (PE) router.	All Levels
Current round-trip-time	Total time taken for completing round-trip of packet.	All Levels
Best two-way channel delay	Best available two-way channel delay count.	All Levels
Worst two-way channel delay	Worst available two-way channel delay count.	All Levels
Average two-way channel delay	Average of the available two-way channel delay counts.	All Levels
Best round-trip-time	Best available round-trip-time count.	All Levels
Worst round-trip-time	Worst available round-trip-time count.	All Levels
Average round-trip-time	Average of the available round-trip-time counts.	All Levels
Average forward delay variation	Average of the variation in forward delay.	All Levels
Average reverse delay variation	Average of the variation in reverse delay.	All Levels
DM queries sent	Number of queries sent for delay measurement.	All Levels
DM responses received	Number of responses received for delay measurement queries.	All Levels
DM queries timedout	Number of timed out queries sent for delay measurement.	All Levels
DM responses dropped due to errors	Number of loss measurement responses dropped due to errors.	All Levels
Response code	Status of the messages used for delay measurement. Response code can be one of the following: `Success`—Successful response code. `Failed`—Failed response code.	`detail`
Querier transmit timestamp	Timestamp on the query message when the message is sent out the ingress PE router (querier). This is done in the hardware before packet is sent out of an interface.	`detail`
Responder receive timestamp	Timestamp on the response message when the message is received by the egress PE router (responder). This is done in the hardware before packet is received by an interface.	`detail`
Responder transmit timestamp	Timestamp on the query message when the message is sent out the egress PE router (responder). This is done in the hardware before packet is sent out of an interface.	`detail`
Querier receive timestamp	Timestamp on the response message when the message is received by the ingress PE router (querier). This is done in the hardware before packet is received by an interface.	`detail`
