INSTALLATION AND OPERATION MANUAL
RLXE4GE24MODMS
TECH SUPPORT: 1.888.678.9427
Ended
Single: Single ended Loss Measurement implemented on LMM/LMR.
Dual: Dual ended Loss Measurement implemented on SW based CCM.
FLR Interval
This is the interval in seconds where the Frame Loss Ratio is calculated.
Flow Counting
Traffic (service frames) are counted per flow - all priority in one.
Oam Counting
Loss Measurement can count OAM frames in different ways.
Y1713: Loss Measurement is counting OAM frames as service frames as described
in Y1731.
None: Loss Measurement is NOT counting OAM frames as service frames.
All: Loss Measurement is counting all OAM frames as service frames.
Loss Measurement State
Near End Loss Count The accumulated near end frame loss count - since last 'clear'.
Far End Loss Count
The accumulated far end frame loss count - since last 'clear'.
Near End Loss Ratio
The near end frame loss ratio calculated based on the near end frame loss count
and far end frame transmitted - in the latest 'FLR Interval'. The result is given in
percent.
Far End Loss Ratio
The far end frame loss ratio calculated based on the far end frame loss count
and near end frame transmitted - in the latest 'FLR Interval'. The result is given in
percent.
Clear
Set of this check and save will clear the accumulated counters and restart ratio
calculation.
Delay Measurement
Enable
Delay Measurement based on transmitting 1DM/DMM PDU can be enabled/
disabled. Delay Measurement based on receiving and handling 1DM/DMR PDU is
always enabled.
Priority
The priority to be inserted as PCP bits in TAG (if any).
Cast
Selection of 1DM/DMM PDU transmitted unicast or multicast. The unicast MAC will
be configured through 'Peer MEP'.
Peer MEP
This is only used if the 'Cast' is configured to Uni. The 1DM/DMR unicast MAC will
be taken from the 'Unicast Peer MAC' configuration of this peer.
Way
One-Way: One-Way Delay Measurement implemented on 1DM.
Two-Way: Two-Way Delay Measurement implemented on DMM/DMR.
Tx Mode
Standardize: Y.1731 standardize way to transmit 1DM/DMR.
Proprietary: Vitesse proprietary way with follow-up packets to transmit 1DM/DMR.
Calc
This is only used if the 'Way' is configured to Two-way.
Round trip: The frame delay calculated by the transmitting and receiving
timestamps of initiators. Frame Delay = RxTimeb-TxTimeStampf
Flow: The frame delay calculated by the transmitting and receiving timestamps of
initiators and remotes. Frame Delay = (RxTimeb-TxTimeStampf)-(TxTimeStampb-
RxTimeStampf)
Gap
The gap between transmitting 1DM/DMM PDU in 10ms. The range is 10 to 65535.
Count
The number of last records to calculate. The range is 10 to 2000.
Unit
The time resolution.
