We enable soft loopback from U2000/CLI for the RFC2544 test, however, we are observing that this soft loopback is normalized by itself after some time (typically 5 – 7 mins). We need to know how can we put permanent soft loopback using U2000/CLI over which we can run the RFC2544 test for at least 2 - 6 hours. We need to test the ATN910, NE20, and NE40 series.

Hi,Steelblue
The default loopback test duration on the device side is 5 minutes.
1. Run the following command to change the default time on devices then test:
[router]system
[router]loopback autoclear period (1-2880 min)
[router]commit
2. Run the following command to enable the loopback test on an interface:
[router]
[router]interface GigabitEthernet 2/0/0
[router-GigabitEthernet2/0/0] loopback local
[router-GigabitEthernet2/0/0]commit
You can also run the u2000 command to enable the loopback test on a specific port.
