IP address does not change on ISE after changing ssid

Leftz — Wed, 15 Sep 2021 19:47:15 GMT

Hi We have catalyst 9800 wlc with Corp, and Guest ssid. When client is connected to ssid Guest, on ISE, we can see ip address (192.168.1.10) which is from Guest ssid subnet dhcp. However, client changed ssid from Guest ssid to Corp ssid, we still can see Guest ip address 192.168.10 on ISE, and Corp ip address does not show up though we can see Corp ip address at PC. How can we explain it? Is this normal? Thank you

when you change the client from One SSID to another ? did he get new IP address from CORP ?

where is your DHCP ? VLAN DHCP Release option in ISE ?

Yes, when change the client from one SSID to another, the client get a new ip address from CORP. I can see the ip from PC via ipconfig

DHCP server is located at the WLC for CORP without DHCP option, and DHCP server for Guest ssid is located at firewall
