I have a single stack of 3850 switches to which my APs are directly connected.
My APs are registered and I have created 2 WLANs to which I can authenticate, associate and pickup an IP address just fine.
VLAN 53 - Wireless APs (no WLAN configured) 10.33.53.1 /24
VLAN 54 - Corporate-Wifi 10.33.54.1 /24
VLAN 56 - Testing-Wifi 10.33.56.1 /24
When connected to either of my WLAN networks I can ping it's on default gateway SVI (VLAN Interface) on the switch but am unable to ping any other device on the network whether on a wired or wireless VLAN.
If I configure a wired client on any of the above VLANs I am able to ping everything (servers and VLAN interfaces)
Has anyone else come across this issue before or am I missing something!
Best Regards
Mark

Hi Mark,
What is the IOS-XE you are running on your 3850 ?

Hi Rasika,
Thanks for your response. I am currently running 03.06.00E but have also tried 03.02.03 with the same results.
Thanks

Hi Mark,
I am running 3850 in 3.6 code, but my SVIs are not in 3850. Set up is working fine.
I will give it a try your setup in one of my test 3850 to see if I can recreate your issue.
For the time being I would suggest reach TAC as issue looks weird.

Hi Rasika
Thanks very much, appreciated.
I will get onto TAC and if you could let me know what you find that would be great.
I have to say, I have been reading your blog a lot recently! Great work.
Thanks

Hi Mark,
I have tested in my lab environment & no problem of inter-valn routing.
Here what I have done
Vlan40 192.168.40.1 <- wireless user vlan map to SSID
Vlan41 192.168.41.1 <- AP management vlan
Vlan42 192.168.42.1 <- Wired vlan
Here is the SSID configuration
wlan OPEN 20 OPEN
no broadcast-ssid
client vlan 40
no security wpa
no security wpa akm dot1x
no security wpa wpa2
no security wpa wpa2 ciphers aes
no shutdown
Once I connect to this SSID, my laptop got 192.168.40.51. I have connected wired device to vlan 42 switchport & that got IP 192.168.42.52. As you can see below I was able to ping wired client from wireless client.

Mark,
Did you ever find a solution to your problem? I am seeing the same issue, except it is intermittent. It occurs every few days, and rebooting the 3850 fixes the problem. I haven't been able to figure out what exactly rebooting the switch clears.
