One device always keeps in On_Pending status in the device window. How 
can I do?

A device in the On_Pending status means there are some pending tasks the Vantage CNM 
should set but has not been set on the device. If the device keeps in the status for a long time 
(for example, over 30 minutes), this may cause the inconsistency between the Vantage CNM 
and the device. Try to do the following.

1 Refresh the device window to get the latest device status. Make sure the connection 

between the device and the Vantage CNM is ok.

2 Make sure the Vantage CNM’s public IP address is properly configured. (For example, 

you can not use 127.0.0.1.). And this IP address should match the one configured in the 
managed devices. If you need to change the Vantage CNM’s public IP address, you have 
to restart the managed devices or Vantage CNM server to reset the connections. See the 
procedure to change this IP address in the 

. 

3 Device firmware backup/restore or configuration file backup/restore on the Vantage 

CNM has upload/download files on the FTP server. Make sure the FTP server is 
properly configured, the connection and the FTP account’s permission are ok. See 

V

Why do I always fail to upload a firmware file to the Vantage CNM?

1 Make sure if you have configured the FTP information properly in the CNM System 

Setting > Configuration > Servers > Configuration. You can use the CNM System 
Setting > Configuration > Servers > Configuration > Status screen to check if the 
connection is ok between the Vantage CNM and the FTP server.

2 Vantage CNM uses the FTP account you provided to ftp the server. And create a /

vantage folder for the file upload/download under the account’s directory. Therefore, 
make sure the FTP account’s permission includes Files (read/write/delete), Directories 
(list/create/delete) and Sub-directories (inherit).
