[trinawong]

Dear all,

Can anyone advise why the ping response is such a different for seg-loopback & end-loopback ping?

Type escape sequence to abort.

Sending 5, 53-byte end-to-end OAM echoes, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 28/28/28 ms

Hello,

End loopback Verifies end-to-end PVC integrity and Segment loopback Verifies PVC integrity to the neighboring ATM device.

So, if I have 4 ms in the seg-loopback and 60 ms in end-loopback, where is the problem?

Thank you
