Clients stuck on IP Learn

Odd functioning. We have some clients that have no issues with connecting and showing Run, while getting proper IP. Some clients just stagnate and drop. No MAC filtering, and clients all on same VLAN.

 

Here is a log of one of those...any ideas why? I saw a bug issues in the past on this, but we are running 17.3.3 on 9800 LC

I did see this bug report: Client stuck in IP learn state with FlexConnect local switching + central DHCP + DHCP required

I assume this issue solve with config ip address with SVI?

Still stuck in ip learn ?

Made no difference, tried removing the SVI for the client VLAN 

DHCP for Wifi Client with WLC 
THIS IS REMOVE SINCE it WLC9800
1-config the SVI with IP address "same subnet of VLAN use under WLAN" in both Peer
2-remove the secondary <-secondary IP under the SVI 
3-config the IP helper in both HSRP Peer
here you must check reachability by 
in L3SW
ping DHCP Server IP address Source SVI ip address

two way to config the DHCP external

1. Which setting in the 9800 WLC is this under?

Can you post the policy profile and Flex profile?

Since you have helper configured directly under the SVI, I would suggest to remove the central dhcp under the policy profile if enabled, you may keep the "ip dhcp required" option enabled once the central dhcp option is removed.

wireless profile policy <Name>
no central association
no central dhcp
no central switching
ipv4 arp-proxy
ipv4 dhcp required
no shutdown

Central DHCP is used only in very unique scenarios such as where the DCHP server is not reachable from the branch, but users must get dhcp from a central server.

In facing a similar issue with some clients under the same site that are stuck on IP Learn when they roam on a C9800 runing 17.3.4. The site has AP4800. Another site with C9120 running 17.3.3 has same issue, but this time clients never pass IP Learn status.

This is happening until next Windows re-auth timer, or after manually bouncing Wi-Fi interface.

My scenario is Flex mode, local forwarding and local DHCP. 2 out of 350 sites impacted by this issue.

I have 2 TAC cases open becuase of this.

 

Upgrading to 17.4.3c helped it seemed!

Were you able to resolve this issue?

Thanks!

Upgrading helped. Also ensuring proper SVI and VLAN config. DHCP is usually the cause of concern as well
