It sounds like either the configuration change is not being pushed to the
sensor, or there is a mis-configuration somewhere.
To determine what the problem is we would need the following:
1) the file /usr/nr/etc/managed.conf on the sensor
2) the file /usr/nr/etc/daemons on the sensor
3) the output of nrvers executed on the sensor
4) any /usr/nr/var/errors.managed.### that are on the sensor
5) the output of show run from the router.
Pls. open a TAC case and provide these files and we'll prceed from there.
Thanks,
