After digging deeper I found that its similar issue mentioned in:
---
https://bugs.launchpad.net/horizon/+bug/1349841
---

As mentioned in comment #11, I updated "/usr/share/openstack-dashboard/openstack_dashboard/api/neutron.py" file and the error went away. I will report this issue to engineering team. 

So, for time-being we can follow below workaround:
----
- take backup of "/usr/share/openstack-dashboard/openstack_dashboard/api/neutron.py"
- Replace:
[...]
         fips = FloatingIpManager(request)
         if fips.is_supported():<===
[...]

 with:
[...]
         fips = FloatingIpManager(request)
         if True:
[...]


- restart httpd service.
