Configuring a remote loop back on an interface.

Hello All,

I've been trying to create a remote loop back on a 10G interface on an EX4550. The 4550 is in a remote location and I'm connected it to it via leased 10g ethernet circuit. I want to create a remote loop back so I can attach a JDSU 5812p tester on the circuit and run a bert test on the circuit.

I looked in the tech library and there's an article about setting up the remote loopback like this:

set protocol oam ethernet link-fault-management interface xe-0/0/2 remote-loopback

But the JDSU unit does not detect the loop when I run the 2544 test on it. 

I even added: 

set protocols oam ethernet link-fault-management interface xe-0/0/2 negotiation-options allow-remote-loopback

But that didn't seem to help either.

Any help would greatly be apprecaited.

Thanks

Ben
