Situation :
U2000 Server was deployed to monitor the Access devices MA5603T and corresponding ONTs in order to guarantee the stability of the GPON System.

At Ma5603T, Management IP address through the Meth0/0 was used to connect with the U2000 Server with the specified IP address.

Problem: Customer reported that they cannot achieve the synchronisation of the NE Data on the Ma5603T in order to view the current situation of equipment, including the interface boards panel situations and traffic utilization . Customer also reported that they are unable to receive the alarms on the device. they want to resume the monitoring services on the MA5603T and corresponding devices.

b. Verification of the SNMP Setting
c. Verification of the FTP Server Settings in U2000,including the service testing on FTP and SFTP.
(Service side FTP service Verification )
d. Verification of the FTP client service in MA5603Tby manualy creating a backup task to U2000 server
(Client Side FTP Service Verification)
e. Reset of the FTP service again.
f.Initate the FTP service on both the Ma5603T and U2000 Server.

Root Cause
Abnormality on FTP service in both the U2000 Server and Ma5603T
.FTP service cannot establish the FTP connection successfully. Xftp Watcher should also be reset again.
The FTP service on both the MA5603T and U2000 server have to be reconfigure and initate again .

At U2000 Server, click Service-> FTP Settgin
a. Verificaiton of the Transfer Protocol and File Transfer Service Setting.
b. Configure FTP and SFTP  by default , UserName ftpuser, Password: "Changeme_123". FTP Port is 20 .

At Ma5603T,
a. Activate the FTP
b. Manually start the FTP service by "FTP SET" command. Manually create a ackup task by " Backup cofiguration ftp x.x.x.x ac.cfg"

Check whether the panel from the eqipment can be seen after the synchronisation of the NE data , the alarm should also be displayed accordingly.

our cusotmer can set up routine schedule on backup configuration through snmp and ftp service daily, so that the service can be guarantee to perform normally.
