Initiating Frame Delay Measurement

This article describes the intiation of frame delay measurement.

CLI Configurations

At CUST1

• Initiate a two-way frame delay measurement from MEP at CUST1 to MEP at CUST3.
  your product# ethernet cfm frame delay start type two-way level 5 vlan 2 mac 00:03:02:03:04:02 count 5

• Wait for 5 seconds and view the frame delay buffer to see the result.
  your product# show ethernet cfm frame delay buffer detail

SNMP Configurations

At CUST1

• Initiate two-way frame delay measurement from MEP at CUST1 to MEP at CUST3. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 10]
  % snmp0 set {{fsMIY1731MepTransmitDmInterval.0.1.1.10 100 }}
  % snmp0 set {{fsMIY1731MepTransmitDmType.0.1.1.10 twoWay }}

  % snmp0 set {{fsMIY1731MepTransmitDmStatus.0.1.1.10 start }}

• Verify whether the delay measurement message counter is incremented for the delay measurement messages sent.
