Cisco 9115-AXE web Gui access issue

[d-satbir]

I'm working on configuring the Cisco AP 9115-axe as embedded wireless controller. So far I've changed the AP to EWC mode and configured the hostname, IP and route. AP is connected to Cisco 9200 switch running version 17.9.4a, EWC is running version 17.12.4. The switchport is configured as trunk interface. 

The issues I'm having so far, I can't ping Interface G0 interface IP and neither the gateway. I also can't access the GUI of EWC, getting the error "this site can't be reached". I've tried accessing the EWC Gui from the MGMT vlan and no smoke. 

*** Configuration from the EWC Interface G0 ***
interface GigabitEthernet0
mac-address <Mac address> 
ip dhcp client client-id GigabitEthernet0
ip dhcp client broadcast-flag clear
ip address <IP address from management VLAN> 255.255.255.0
negotiation auto

*** Switch Interface ***

Int g1/0/5

switchport mode trunk

switchport trunk native vlan <VLAN ID>

Please Advise? 

Thank you.

V/R,

Another thing I forgot to mention, I'm seeing unknown protocol drops increment as I've tried pinging or tried to access to GUI.

@d-satbir search around the forums as there are other post with the same type of issue.  This way you can gather some data and see what works. Search Cisco EWC GUI as an example.  You can find some troubleshooting and also steps to actually configure EWC.  Maybe you missed a step, because there is more than what you have to get the GUI working.

@d-satbir did you miss a step, curious on what fixed it.

Initially I was assigning the IP statically to EWC. After going through the link provided gave me an idea to get an IP address through DHCP, so I enabled DHCP on the management VLAN. That gave me an IP address for EWC and an AP which worked just fine. That also resolved my ping issue.

Thanks for providing what fixed your issue.  That helps a lot.
