This article shares with you a case about Huawei MA5800 X7 can not synchronize with NCE through the VPN instance. I hope you like it!
Issue description
The NCE can not manage the MA5800 X7, the synchronization by ftp/sftp or tftp is not successful. The NE backup can not be done.
Handling Process
1. The NCE can ping OLT, but OLT can not ping NE directly.
2. The OLT has inband management, VLAN interface uses a VPN Instance.
Root cause
The VPN instance corresponding to the xFTP server is not configured. The xFTP Server is the NCE. For this reason is not possible to synchronize the NE or backup the data configuration.
Solution
The VPN instance assigned to the xFTP Serverv(NCE) should be specified according to the following command:
sysman sftp vpn-instance 192.**.**.10 VPN_NAME
Summary
The sysman vpn-instance(xFTP) command is used to configure the VPN instance corresponding to an xFTP server. You can select a VPN instance as the one corresponding to the IP address of an xFTP server by running this command. After this command is executed successfully, when a device communicates with the user-specified xFTP server, it processes only requests on the corresponding VPN but not requests from other VPNs or public networks.
