The model name of the device is changing from the sysName to the IP address when reconfiguring a device in maintenance mode.
Release : 10.3
Release : 10.4
Component : Spectrum Core / SpectroSERVER
We are deriving model names using the below options in the order (a) sys name (b) IP address and (c) name service . When the device is in maintenance sysname is not accessible and IP address is used.
This is functioning as designed. The SysName is not available when the device is reconfigured while in maintenance mode so the model name is changed to the IP address.
