Hello Peter,
not all fields are described in OER command reference
http://www.cisco.com/en/US/docs/ios/oer/command/reference/oer_03.html#wp1065811
but you can find there some explanations
Los = Loss
MOS : indicates packets containing MOS payload in order to perform VoIP quality test
so LoMOSCnt should be number of MOS packets lost
MOSCnt : total number of MOS packets
Ibytes = ingress bytes
Ebytes= egress bytes
OOP/Rtechg = second part should stay for route change, first part could mean out of path packets that have travelled on other paths rather then on monitored /expected ones
Dsum could be the sum of delays (750) to be used to calculate average delay and jitter (delay variation)
if so Comps could mean compliant samples (with delay in SLA)
Hope to help

Hi Giuseppe,
Thanks for the tip! I wonder why Cisco doesn't document this information. These statistics seem meaningless if you don't know what they are. Oh well.
Do you mind taking a quick glance at the below; I've tried to expressly document every stat. In particular, I'm still confused about "Samples," "Attempts," "Comps," and "Jitter." (I know what jitter is, but don't see how it is calculated here.)

Sorry, for some reason the rest of my email was chopped off. Here's what should have appeared after the above text:
---------------------------------------------------------------------------
Age Timestamp marking the end of a monitoring period
Border IP of Border Router
Interface Int on Border Router
OOP/RteChg Reasons Number of packets which have traveled on Out Of Path (OOP) routes than over monitored ones.
Pas:DSum Sum of packet delays to be used to calculate average delay and jitter
Pas:Samples ???
Pas:DAvg Average Delay per packet (Pas:Dsum/Pas:Pkts)
Pas:PktLoss Number of packets lost
Pas:Unreach Number of packets sent to an unreachable prefix
Pas:Ebytes Number of bytes egressing the router
Pas:Ibytes Number of bytes ingressing the router
Pas:Pkts Total number of packets seen on this interface
Pas:Flows Total number of flows seen on this interface
Act:Dsum Sum of packet delays to be used to calculate average delay and jitter
Act:Attempts ???
Act:DAvg Average Delay per packet (Act:Dsum/Act:Pkts)
Act:Comps Compliant samples (???)
Act:Unreach Number of packets sent to an unreachable prefix
Act:Jitter ???
Act:LoMOSCnt Number of MOS packets lost
Act:MOSCnt Total number of MOS packets
---------------------------------------------------------------------------
Thanks!

Hello Pete,
I tried to look for MOS test description.
There are a number of qualifiers frequently appended to MOS, including MOS-CQS, MOS-LQS, etc. Refer to ITU-T Recommendation P.800.1 for a description of those.
Resources: ITU-T Recommendations P.10, P.800, and P.800.1
http://www.itu.int/itudoc/itu-t/aap/sg12aap/history/p800.1/p800.1.html
this should give you hopefully a background to understand all the terms
Hope to help

Great, thanks Giuseppe!
I'm surprised Cisco doesn't have some official documentation, but oh well. The link you've found looks very promising, though. I think it will do.
Many thanks!
