Scenario There is a problem with the East-WLC-2504A. When configuration changes are made to the Employees-East-Wing AP Group that covers the East-Wing, none of the APs receive the updates. Referto…

Replacing the AP in the group is not required because the problem lies in interface and group parameter misconfigurations, not in which physical AP is assigned.

The east-wing interface IP address is not identified as a misconfiguration contributing to the AP group update failure in this scenario.

Changing the VLAN Identifier on the east-wing interface is not one of the four misconfigurations causing APs to miss group updates.

Dynamic AP Management must be enabled on the east-wing interface so the WLC uses that interface to exchange management and configuration traffic with associated APs. Without it, the controller cannot deliver AP group updates through that interface, which is the root cause of the described failure.

The port number assignment is not the source of the AP group failure and changing it is not among the required fixes identified in this scenario.

The 3700-East-Wing AP must have the Primary Controller name and IP address explicitly configured so it can locate and join the correct WLC. Without this setting, the AP may not associate to East-WLC-2504A at all and therefore never receives group configuration updates.

The SSID configured in the Employees-East-Wing AP Group must exactly match the WLAN SSID defined on the controller. A mismatch causes the AP group to reference a non-existent or wrong WLAN profile, preventing proper updates from propagating to member APs.

The Interface or Interface Group assignment in the Employees-East-Wing AP Group must be mapped to the correct dynamic interface. Without the correct interface binding, client traffic cannot be bridged to the right VLAN and the AP group configuration is effectively broken.
