Label Description
Far-End Mac Addr Displays the MAC address of the far-end (remote) node.
Duration(sec) Displays the duration that the current test has been running.
Latest Frame
Counters
Indicates that the number of frames counted are the latest values:
• For single-ended tests, the values are for the previous.
• LMR, the current LMR, and the difference between them.
TxLocal Displays the latest number of frames transmitted from the local Router.
RxFarEnd Displays the latest number of frames received at the remote Router.
TxFarEnd Displays the latest number of frames transmitted from the remote Router.
RxLocal Displays the latest number of frames received by the local router.
Accumulated Frames Indicates that the frame counter values under this heading are the accumulated values
for the near-end (local) and far-end (remote) routers.
Total Tx Displays the total number of frames transmitted during the test.
Total Rx Displays the total number of frames received during the test.
Total Loss Displays the total number of frames lost during the test.
Loss Ratio (%) Displays the loss ratio, defined as follows:
Loss Ratio (NE) = Total Loss (NE) ÷ Total Tx (FE) x 100%
Example (single-ended):
• NE loss ratio = (1 ÷ 36) x 100% = 2.78%
• FE loss ratio = (0 ÷ 30) x 100% = 0.00%
