Hi @hamza11,
Thanks for your patient.
After the troubleshooting, we found two error in your project.
1. On the AC, you forgot bind the ap-id 0 to the ap-group huawei.
ap-id 0 type-id 69 ap-mac 00e0-fc7c-6d30 ap-sn 210235448310F4274F27
ap-name AP1
ap-group huawei //The forgotten command.
2. On SW2, VLAN 30 is not created, which will cause the laptop cannot get the IP address from SW1.
After correcting these two errors, the STA could connect to the AP and get the IP address correctly.
