Cisco 9130X not getting IP Address from DHCP server running on switch

[pgill.uwo@gmail.com]

Hello All
Looking for help on troubleshooting access point 9130X. I have DHCP server/scope running on Cisco 9200 ( switch 1 ) and can see it is handing IP address to AP but I am not able to ping/reach Access point. I have switchport setup to access port ( switch 2 ) but when doing cdp neighbor detail I am not seeing any IP address on Access point. Not sure what is wrong. Is leasing expiring ? ( odd ) Here is my config

Switch 1 configuration : Running DHCP
ip dhcp pool WirelessMgt_DHCP
network 192.168.11.0 255.255.255.128
default-router 192.168.11.1
service dhcp
output of ip dhcp binding:
192.168.11.62 01xx.11xx.623a.dx Oct 03 2022 04:18 PM Automatic Selecting Vlan710
( not correct MAC I changed some characters)

Switch 2 configuration:
switchport mode access
switchport access vlan 710
cdp neighbor detail shows AP MAC which is same as one in dhcp binding but without IP address.

Appreciate everyone's help.

Agreed with @Arshad Safrulla - update WLC to latest 17.3 as per TAC recommended (currently 17.3.5b) if you need to use 17.3 otherwise consider upgrading to 17.6.4.

CAPWAP protocol was tweaked in 17.6 which caused incompatibilities with older AireOS (https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx98176) but might also be the cause of what you're seeing.

Did you save the config before you upgraded the controller?
What do the logs on the controller show?
Do you have a backup of the controller config?
If for some reason you lost the config during upgrade (unlikely but not impossible - we've only seen that happen on a HA pair when one of them crashed and they then synced a blank config - Cisco TAC couldn't work out why) then you can simply paste the config back in.
