Synthetic loss measurement
6
• Synthetic loss measurement should not be configured over VLAN untagged ports in the case of
a regular VLAN.
• When COS 8 is used on an initiator and responder, a cos value is randomly chosen between
0-7 before transmission of an Synthetic loss measurement (SLM) packet. On the responder
side, all SLM packets for the target MEP are accounted for session 8 by ignoring the COS.
Similar handling is present for Synthetic Loss Reply (SLR) processing. SLR packet uses the
same cos which was present in the incoming SLM packet.
• When synthetic loss measurement is configured over VPLS untagged end-point, only cos 8 can
be used.
• The initiator and responder for a particular SLM session should have the same cos configured
on both ends.
• Other than an immediate case, the start and stop configuration will always be a part of the
running configuration. It is persistent after a reload.
• The stop now command stops any running session. It cancels the start of any scheduled
session. In addition, it also resets the start/stop time to "00:00:00" and type to “Immediate”
for non-periodic sessions.
• Session configuration cannot be changed when it is running.
• Before configuring any SLM session, ensure the device is configured with the correct date and
time. Use the show clock command to verify. Otherwise bring the clock to present time with the
set clock hh:mm:ss mm-dd-yy command.
• Synthetic loss measurement (SLM) and Synthetic Loss Reply (SLR) packets are not transmitted
or received over blocked ports.
Commands
The following commands are described for the initiator and the responder.
DUT(config-cfm)#loss-measurement slm initiator
Syntax: loss-measurement slm initiator | responder | clear-stat
Initiator - is used configure synthetic loss measurement parameters on Tx side.
Responder - is used to configure synthetic loss measurement parameters on Responder side.
Clear-stat - is used to clear the history logs globally.
DUT(config-cfm)#loss-measurement slm initiator 1
Syntax: loss-measurement slm initiator session_index
Session_index - is used to configure the session index in range. The acceptable range is 1 -
1000.
DUT(config-cfm-loss-measurement-slm-initiator-1)# domain
Syntax: domain
Domain - is used to configure the domain name
DUT(config-cfm-loss-measurement-slm-initiator-1)# cos 1
Syntax: cos cos
Cos- is used to configure the priority value. The acceptable range is 1 - 8. The default is 7.
DUT(config-cfm-loss-measurement-slm-initiator-1)# tx-interval 1
Syntax: tx-interval interval
Interval - is used to configure the Tx interval between SLM packets (default - 1sec).
