Configuring and Enabling Test Messages

This article describes the steps to configure and enable the transmission and reception of TST PDU by an MEP.

CLI Configurations

To configure and enable test messages

1. Execute the steps given in CLI Configurations to configure MEP before sending the test messages.

2. Execute the steps given in section CLI Configurations to enable ECFM and Y.1731 for Y.1731 test message feature.

3. Send the TST message to an MEP using destination’s MAC address.
   your product# ethernet cfm test mac 00:02:02:03:04:03 level 7 vlan 101 count 5

TST to 00:02:02:03:04:03 from 00:01:02:03:04:03 with 33(64) bytes of data.
60 bytes to 00:02:02:03:04:03: seq_no=0
60 bytes to 00:02:02:03:04:03: seq_no=1
60 bytes to 00:02:02:03:04:03: seq_no=2
60 bytes to 00:02:02:03:04:03: seq_no=3
60 bytes to 00:02:02:03:04:03: seq_no=4

For sending a Test message to an MEP using destination’s MEPID

Example: ethernet cfm test mpid 2 level 6 vlan 5 count 5

1. If the user does not provide target MPID and MAC Address, it will be treated as multicast TST messages.

2. For a VLAN-UnAware MEP, vlan keyword must not be provided with the command.

3. ECFM and Y.1731 should be enabled for the successful Test message transmission.

4. count and deadline keyword, if not provided, assumes infinite number of test messages to send.

SNMP Configurations

To configure and enable test messages

1. Execute the steps given in SNMP Configurations to configure MEP before sending the test messages.

2. Execute the steps given in SNMP Configurations to enable ECFM and Y.1731 for Y.1731 test message feature.

3. Send the TST message to an MEP using destination MAC address. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-Index = 5]
   %snmp0 set {{fsMIY1731MepTransmitTstDestMacAddress.0.1.1.5 00:02:02:03:04:03 }}
   %snmp0 set {{fsMIY1731MepTransmitTstMessages.0.1.1.5 5 }}
   %snmp0 set {{fsMIY1731MepTransmitTstStatus.0.1.1.5 start }}

[Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-Index = 5]
% snmp0 set {{fsMIY1731MepRowStatus.0.1.1.5 notInService }}
% snmp0 set {{fsMIY1731MepTstCapability.0.1.1.5 enabled }}
% snmp0 set {{fsMIY1731MepRowStatus.0.1.1.5 active }}
