Enabling Jitter Monitoring
The
jitter
command, in Specific Maintenance Association mode, enables jitter monitoring. The

Argument Description
bucket-size <10-20>
Number of CCM packets used to calculate performance
parameters (one-way jitter calculation). Range is <10-20> packets.
The default value is 10.
threshold-error
<
1-
10000
>
One way jitter threshold value for which an error message is sent.
The default value is 350ms.
threshold-warning <1-
10000>
One way jitter threshold value for which a warning message is
sent. The default value is 300ms. If the specified value is greater
than the jitter-error, the warning will be disabled.
