The supported Delay Measurement tool parameters are as described in Table 3-7, Delay Measurement Tool parameters:

Table 3-7: Delay Measurement Tool parameters

Parameter

Description

Resource AID

Indicates the AID of the Terminated TMPLS facility where the DM-Tool has to be configured.

The supported values are:

  • MPLSIF-1-1-2-{7-10} (MPLS Interface)

  • MPLSIF-1-1-{3-4}-1000 (MPLS Interface)

  • TUSEG-1-1-{1-1024} (Tunnel Segment)

Note:

  • The default is that a value is required and the field cannot be left blank.

  • The MPLSIF involved must have MEP=ENABLED

  • The TUSEG involved must have DIR=BIDIR

  • The TUSEG involved must have TYPE=TERMINATED

  • The TUSEG involved must have MEP=ENABLED

PHB

Indicates the PHB value associated to DMM packets.

The supported PHB values in range 1 are{EF, HIGH2, AF21, AF22, AF41, AF42, DE-G, DE-Y}

The supported PHB values in range 2 are {EF, HIGH2, AF1, AF2, AF3, AF4, DE, LOW2}

The default PHB value is EH.

Note:DM-PHB is not supported for on-demand 2-way delay measurement over TMPLS interface The chosen DM-PHB must be present in the PHB profile used by the Terminated TMPLS Tunnel/PW referenced by AID parameter.

Sender DM Tool

MEP point that sends DMM packets and make measurement when receives back DMR packets received from the symmetrical tool RDMT.

Period

Indicates the period for the transmission of DMM packets. The supported values are 1s, 10s, 1m, 10m. The default value is 1m.

Send Packet Number

Indicates the number of DMM packets to send. The Integer value is 32. The default value is 1.

Note: The system can send a maximum of 100 DMM packets for this DM-Tool.

Packet Length

Indicates Length in byte of DMM packet to send.

Packet length 0 indicates a random length between 64 and 9600 bytes. The default value is 64.

Note:The packet length supported on one MPLF interface will be subject to the MTU/MRU configured on the Ethernet port.

4

Click to select the Resource as either Tunnel Segment (TUSEG) or MPLS Port.

5

If TUSEG is selected, a dialog is displayed where the Tunnel Segment can be located and selected. Click to select the TUSEG From and To range and click Search.

6

If MPLS Port is selected, the MPLS dialog is displayed. Click to select the Board and click search for the port listing.

7

Click to select the port as resource.

8

Select the PHB profile as applicable from the drop-down.

9

Select the number of samples for the Sender DM Tool.

10

Select the Sender period.

11

Select the Frame length in bytes or the random range from bytes to MTU.

12

Click Save to save the configuration or click Cancel to return to the previous screen without saving.

End of steps

Modifying Delay Measurement

Use the following procedure to modify the Sender Delay Measurement tool parameters.

 
1

Navigate to the Delay Measurement Tool screen. Under the Active DM Sessions Retrieval, specify a DM Tool value between 1 and 100.

2

Click Search/Refresh to locate the DM tool to modify and select.

3

Modify the DM tool parameters as required. Refer Table 3-7, Delay Measurement Tool parameters for parameter descriptions.

4

Click Save to save the modifications or click Cancel to return to the previous screen without saving.

End of steps

Deleting a Delay Measurement
 
1

Navigate to the Delay Measurement tool.

2

Enter the From and To DM Tool values and click Search/Refresh.

3

Click to select the DM tool to be removed and click Delete.
