Release : 10.4.1
Component : Spectrum CORE
Spectrum will bind processd to the physical NIC ip address while Spectrum processes like LocServer will bind to the ip it was installed on. This will create problems and Spectrum will not function properly.

It is not possible or recommended to install Spectrum on a subinterface and should only be installed on a static ip address that is from the NIC.
