UI: Guest physical networks with VXLAN doesn't accept VNI ranges > 4095 during zone creation

[zap51]

ISSUE TYPE

• Bug Report

COMPONENT NAME

UI, API

CLOUDSTACK VERSION

Tested v4.16.1.0 onwards

CONFIGURATION

Advanced networking

OS / ENVIRONMENT

Ubuntu 20.04 and later

SUMMARY

On adding a new zone from the WebUI and when the Physical Network for Guest traffic is specifically chosen as VXLAN, zone creation fails as the VNIs can not be set greater than 4095

STEPS TO REPRODUCE

1. Use the wizard on WebUI to create a new zone.
2. Choose Advanced Networking.
3. Add details of the zone and choose KVM.
4. Create physical networks as follows

5. Add Public and System VM networks.
6. Add the VNI ranges greater than 4095

7. During the final addition, an exception is thrown saying VLAN or VNI ranges should be in range 0 - 4095.

EXPECTED RESULTS

The zone addition with VXLAN isolation should go through when the VNI ranges are greater than 4095 for Guest Network. 

ACTUAL RESULTS

During the final addition, an exception is thrown saying VLAN or VNI ranges should be in range 0 - 4095. Also, let's say we input 3701 - 3702 as the dummy ranges during addition, the range "3701 - 3702" actually gets applied on "Public Network" as dynamic range of VLANs. The Physical Network for "Guest" still doesn't have any dynamic VLAN IDs or VNIs hence manual addition is required.
