I was working on a GE interface and needed to do some loop testing. I can't use BERT because it is GE, so my next option is to send pings over the loop.
Traffic to the local IP address is not send out the interface by default, so my search for the correct format led me to here:
http://www.juniper.net/techpubs/software/nog/nog-interfaces/html/atm-loopback9.htmlThe syntax for the command is "ping interface at-fpc/pic/port-IP-address bypass-routing count 1000 rapid"
I mirrored this with my 10G interface "ping interface ge-1/0/0.0 10.10.1.1 bypass-routing count 1000 rapid"
The command seemed to complete, but my response times were in the 0.02 ms range when I was expecting something closer to 5 or 6 ms indicating that the traffic was not being transmitted out the physical interface. (the response times were the same as a standard ping to a local address)
Does this functionality not exist for GE?
This was using JUNOS 7.x on a T series router.
