What is the authentication method for ONU?
In order to prevent illegal ONT online, it is necessary to be authenticated for ONT. Currently, there are total 3 kinds of authentication methods, however, the last method is restricted only for France area.
1. The first method is sn-auth, this is the most popular authentication method currently. If the reported sn is the same as the sn configed offline, this ONT can be online, otherwise, it is forbidden to be online.
2. the second-method is sn+password auth, of course, it is much saver than the first one, except the sn should be consistant with configuration, it is also needs to verify if password is the same, and this method is mainly used to some conditions which need special security.
3. the sn is unique just like as mac address, but it is not very easy to find sn, so the last authentication method is to skip sn-auth, only left password-auth, until now, this method is only applied for France area.
