monitor mpls delay rsvp
Syntax
monitor mpls delay rsvp lsp-name <detail> <count count> <interval seconds> <padding-size padding-size> <traffic-class traffic-class>
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.
|
| interval seconds | (Optional) Specify in seconds the interval between two successive query messages.
|
| padding-size padding-size | (Optional) Specify the length of padding TLV to be included in the query message.
|
| 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.

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.
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:
|
|
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. |
|
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. |
|
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. |
|
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. |
