38.2 Device Management

One device always keeps in On_Pending status in the device window. How can I
do?
A devices with the On_Pending status means there are some pending tasks the
Vantage CNM should set but has not set to the device. If the device keeps in the
status for a long time (for example, over 30 minutes), this may cause
inconsistency between the Vantage CNM and the device. Try to do the following.
Refresh the device window to get the latest device status. Make sure the
1
connection between the device and the Vantage CNM is ok.
Make sure the Vantage CNM's public IP address is properly configured. (For
2
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 Section 30.1.1 on page
