5.3 Running Diagnostics
When you set up a new connection, you can verify the link connectivity using PING prior to send-
ing data. A Latency and Jitter Test will verify the quality of the link.
5.3.1 PING Testing
You can verify network connectivity with another IP device within the subnet by sending a PING
to the IP address for that device. For PING testing instructions, reference 6913303, 9145E NID
Software Version 1.0 Users Manual.
5.3.2 Latency and Jitter Testing
Latency/Jitter Testing measures and reports performance and quality of the link between the
9145E and another Canoga Perkins capable device. Results reported include the Frame Loss
Ratio (FLR), and the minimums, average, and maximums for latency and jitter. For latency and jit-
ter testing instructions, reference 6913601, 9145E Ethernet Network Interface Device Software
User’s Manual.
