Issue:
Been receiving multiple false alert from spectrum saying " IP address can not be reached by Spectrum at particular time ".
The device is up and pingable.
Cause:
Spectrum relies on the devices and networks ability to respond to packets in a very specific time frame.
Default is 3 seconds.  

In some cases there are high network latencies that can cause this to exceed 3 seconds or more.
Resolution:
Increase the DCM Timeout value for that device.

Navigate to the device in OneClick.
Go to Information tab.
Expand CA Spectrum Modeling Information
Find DCM Timeout

Default is 3000 (ms)
Max value is 60000 (ms), or 1 minute.

Increase this value as required.
