I am able to telnet and manage the NE80E Router from my U2000 and do see all the alarms that can happen but the issue that I am not able to backup the configration for all the NE80E Routers in the network .
on U2000 while try to back up the configuration of the NE80E Router , I receive alarm that backup operation failed for all of the NE80E Routers.
I checked the Whole configration file of the NE80E Router and I found that the customer has added the U2000 IP address under VPN instance and use command of " set net-manager vpn-instance " .
after checking the command reference for the current version ( V300R002 ) , this command is not supported .
The solution is tp upgrade from V3R2 to V600R001C00 , where the new version support this command otherwise the customer has not to insert the U2000 under the VPN Instance
1) check the SNMP configuration on the NE80E and found the configration is ok .
2) try to ping the NE80E fron the U2000 server ( not from U2000 program ) the ping was ok.
3) check the FTP services on the U2000 SUN Server , the FTP is ok.
4) Use the U2000 SUN Server as FTP server and FTP the NE80E configuration file , the FTP is not working .
the recommended version for the upgrade is V600R001C00SPC800 on the time of submitting this case.
