Test Ethernet packet errors reported by ODU
To test for Ethernet packet errors, proceed as follows:
Procedure 7-12 Test for Ethernet packet errors
1
Log in to the ODU and select Administration, Statistics, Detailed Counters.
2
Select Reset System Counters at the bottom of the page and wait until
the Ethernet Rx Packets counter has reached 10 million.
NOTE
The count will only update when the page is refreshed.
3
If the counter does not increment or increments too slowly, because for example
the PTP 600 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
7-11.
4
Check the Ethernet Rx Crc And Align counter. The test has passed if this is less
than 10.
Test Ethernet packet errors reported by managed switch or
router
If the PTP 600 is connected directly to a managed LAN device, for example an
Ethernet switch or router, it should be possible to carry out a check on the rate of
errored Ethernet packets monitored by the managed device. Please refer to the user
guide of the managed LAN device.
The test has passed if the rate of packet errors reported by the LAN device is less than
1 in 1 million packets.
