Transmitting Periodic Delay-Measure Messages
Use the Administration > CFM (Configure Periodic Delay Measure) pages to configure periodic
transmission of delay-measure messages. These messages can be used to measure frame delay
and frame delay variation between MEPs.
CLI References
• “CFM Commands” on page 517
Command Usage
• Follow these steps to transmit periodic delay-measure messages:
• Use the “Add Group” page to create a messages attribute group which defines the overall
message cycle, the duration of the transmission, the interval between message
transmissions, the message length, and the timeout to wait for a response.
• Use the “Configure” page to specify one-way or two-way delay-message transmissions,
bind a message attribute group to a local MEP, and designate the target MEP.
• Both the source and destination MEP must be configured for the same MA before transmitting
delay-measure messages.
• Results of periodic delay measure testing will be recorded in the system log after completion of
each full cycle.
• The settings of an existing attribute group cannot be modified. First delete the group, and then
redefine the attributes. To delete an attribute group, unbind it from any local MEPs by setting
the Group Index parameter to “none” on the “Configure” page, and then deleting the group
from the “Show Group” page.
• A MEP cannot transmit periodic delay-measure and on-demand delay-measure messages at
the same time.
Parameters
These parameters are displayed:
Add Group
• Group Index – Attribute group index. (Range: 1-200)
• Cycle – The periodic cycle at which delay-measure messages are transmitted.
(Range: 1-24 hours; Default: 4 hours)
• Duration – The duration of each transmission. (Range: 1-60 minutes; Default: 10 minutes)
• Interval – The interval between each transmission. (Range: 1-5 minutes; Default: 1 minute)
