Static IP address provide to client device can't networking

[eeebbunee]

Hello Professionals,

I'm wondering my curiosity can be resolved from Wireless topic or Switch topic.
For the beginning, I would like to share that I'm having WLC9800-L-K9 with 17.13 version and C9300L switch(17.06) as a DHCP server.

 - Client PC connects to WiFi (SSID-A): Success, getting IP address from Core switch. (10.100.100.30/24)
 - I manually provide IP address to Client PC which is in SSID-A's IP subnet(10.100.100.31/24) : Seems wifi connected, but can't talk with my IP address. (Can't ping to gateway, can't reach to internet/server) - IP address is not duplicated with other devices

Static binding from Core switch is working, but manual IP binding to client PC can't.

Is this happened due to WLC's configure or Core switch config?
I believe Clients should have all IP address from centrally, not by themselves so this result is good to me in management terms but still want to know why.

Thank you for giving your precious time.

Try disable option

Dhcp assignments in wlan advance.

If this op. Is enable wlc not allow client to finish auth.

If you are giving static IP address to the PC, you need to enable Passive Client inside the Policy Profile and try to test by disabling IP-MAC binding.

Hello @Saikat Nandy 

I appreciate your response. 
SSID-A has enabled 'IP-MAC binding' unlike other SSIDs I made.
When I disable this feature, I was able to manually provide IP address.

However, I remember enabling IP-MAC binding caused issue to get IP address from DHCP server. I couldn't get IP address from the DHCP server until I disable this feature. 
Could you teach me on how this feature works? I would like to keep this enabled, but still worried that client can't get IP address correctly like before.

Thank you very much.

well I would expect endpoint to get an ip from dhcp server while ip-mac binding is enabled. I would suggest you to have a look into the config of 9800 and if possible share 'show tech wireless' from WLC, so that we can have a look too. Here are couple of docs you can refer for passive client and IP-MAC binding -

You should not be using 17.13 because it's a limited support, feature only, release which will never get any bug fixes!
Refer to the TAC Recommended link below - you should either be using 17.12 or 17.15 - which are the recommended Extended Support releases with regular bug fix maintenance releases for up to 2 years.
