Yes, in a topology that includes a RouterBOARD RB3011 and a MikroTik CRS125 switch, it is possible to manage access points (APs) from the RB3011 using CAPsMAN (Controlled Access Point system Manager), which is MikroTik's solution for centralized management of multiple Wi-Fi APs.

CAPsMAN allows you to configure, control and monitor all your APs from a single device, in this case, the RB3011, which significantly simplifies the management of a wireless network.

For this to work, you will need:

1. Configure CAPsMAN on the RB3011: This involves enabling the CAPsMAN package if it is not enabled, creating a configuration for channels, security settings, and any other specific settings your APs will need to use.
2. Configure APs to be managed by CAPsMAN: The APs must be configured to operate in CAP (Controlled Access Point) mode. This can be done by accessing each AP and changing their configuration so that they register with the CAPsMAN on the RB3011. You will need to specify the IP address of the RB3011 as the manager to which the APs should connect.
3. Connect the RB3011 and the APs through the CRS125: Make sure that both the RB3011 and all APs are connected correctly through the CRS125 switch and can communicate with each other. The CRS125 simply acts as a switch in this configuration, passing traffic between the RB3011 and the APs.
4. Verification and management: Once the APs are configured as CAPs and the RB3011 is configured as CAPsMAN, you should be able to see all registered APs in the RB3011's CAPsMAN interface. From here, you can manage the configuration of the APs, update them and monitor their status.

Remember that CAPsMAN is a powerful solution that requires careful configuration to function correctly.

Be sure to review MikroTik's documentation and follow best practices for configuring your CAPsMAN network, especially as it relates to Wi-Fi network security, to protect your network and your users' data.
