service-module t1 remote-loopback

[affability]

If I configure the command "service-module t1 remote-loopback" on an MPLS WAN interface remotely will I lose connectivity to the device?

That depends if the device to which the router is connected, obeys to requests for loopback. If it does, yes.

It is not an important test however, mainly there for approval requirements.

Thank you very much for the quick response. It is connected to our ISP. So, if the ISP sends a loop reqeust to my router while "service-module t1 remote-loopback" is configured on the WAN MPLS interface, that will bring down the circuit while in loop/test?

To deny requests:

no service-module t1 remote-loopback full.

Fortunately, SPs don't act to bring their customer down.

Sorry, I'm still failing to understand the configuration.

So, if I configure my interface with "service-module t1 remote-loopback" my device will send out loop requests to the SP. And if their equipment responds and creates the loop, my equipment will not be accessible until the loop is broken? I looked at the command reference and command configuration guidelines but it does not specify whether the circuit will be terminated. can you advise?

No, the request is sent with the "loopback remote" command.

The overall loopback features are configured with the "service-module loopback" command.

During loopback test of any kind, circuits cannot be used.
