Test Ethernet packet errors reported by ODU
To test for Ethernet packet errors, proceed as follows:
1
Log in to the unit and select menu option Statistics.
2
Select Reset Counters at the bottom of the page and wait until the Data
Port Rx Packets counter has reached 1 million.
3
If the counter does not increment or increments too slowly, because for
example the link is newly installed and there is no offered Ethernet
traffic, then abandon this procedure and consider using the procedure
Test ping packet loss on
page 8-9.
Test Ethernet packet errors reported by managed switch or
router
If the ODU is connected to a managed Ethernet switch or router, it may be possible to
monitor the error rate of Ethernet packets. Please refer to the user guide of the
managed network equipment.
The test has passed if the rate of packet errors reported by the managed Ethernet
switch or router is less than 10 in 1 million packets.
