WEB OPERATION & CONFIGURATION
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.
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 Ration:
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:
Select the checkbox to enable Delay Measurement based on transmitting 1DM/DMM PDU. 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 or Two-Way Delay Measurement implemented on 1DM or DMM/DMR, respectively.
Tx Mode:
Standardize:
Y.1731 standardize way to transmit 1DM/DMR.
Proprietary:
The 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.
