Method used to verify the consistency between physical fiber connections and logical fiber connections on Metro 1000

1. The Metro 1000 V2 does not support query for received J0 bytes. You can change the number of J0 bytes to be transmitted at the local end to be different from the number of J0 bytes to be received at the peer end, and then check whether the J0_MM alarm is reported.
2. You can also insert an MS_AIS alarm and check whether the peer end reports the MS_AIS alarm. Exercise caution because this operation will interrupt services.
