Great clarity on that topic - but, I wonder how round-trip violations are
"established" - It suggests to me that you have to have "management" packets
sent out for the express purpose of creating that awareness - as opposed to
normal production traffic being used to identify those round-trip violations...
(?!?)
I'll look into it.
In the meanwhile, thank you for attaching that reference!

Here is a quote from the DOC-CD for you that does an excellent job of
explaining this:
"IP SLAs includes the capability for triggering SNMP notifications based on
defined thresholds. This allows for proactive monitoring in an environment
where IT departments can be alerted to potential network problems, rather than
having to manually examine data.
IP SLAs supports threshold monitoring for performance parameters such as
average jitter, unidirectional latency and bidirectional round trip time and
connectivity. This proactive monitoring capability provides options for
configuring reaction thresholds for important VoIP related parameters including
unidirectional jitter, unidirectional packet loss, and unidirectional VoIP
voice quality scoring (MOS scores).
IP SLAs can generate system logging (syslog) messages when the reaction
threshold increases or decreases beyond the configured values for packet loss,
average jitter, or MOS. These system logging messages can then be sent as SNMP
notifications (traps) using the CISCO-SYSLOG-MIB.
For packet loss and jitter, notifications can be generated for violations in
either direction (source to destination and destination to source) or for round
trip values. Packet loss, jitter and MOS statistics are specific to IP SLAs
Jitter operations. Notifications can also be triggered for other events, such
as round-trip-time violations, for most IP SLAs monitoring operations."
