What is CAPsMAN?
CAPsMAN is a feature of MikroTik RouterOS that allows you to centralize the configuration and management of wireless access points (CAPs) in a network.
Instead of configuring and maintaining each access point individually, CAPsMAN allows administrators to manage all CAPs from a single point of control.
CAPsMAN Key Features
- Configuration Centralization: With CAPsMAN, you can define centralized configuration policies that will apply to all CAPs on the network. This makes it easy to implement security policies, channel assignment, quality of service (QoS), and other parameters uniformly across all access points.
- Authentication Management: CAPsMAN supports various authentication options, including WPA2, WPA3, and RADIUS-based authentication. This ensures that only authorized devices can connect to the wireless network.
- Seamless Roaming: CAPsMAN enables smooth transition between access points as devices move within the network. This is especially beneficial in environments where mobility is essential, such as offices or hospitality environments.
- Dynamic Channel Management: CAPsMAN can automatically manage wireless channel assignment to optimize performance and minimize interference. This is essential in environments with multiple access points.
- Monitoring and Diagnosis: CAPsMAN's monitoring tool enables real-time tracking of wireless network performance, making it easy to detect and resolve issues.
Benefits of Using CAPsMAN
- Greater Efficiency in Administration: Centralized management simplifies wireless network setup and maintenance, reducing the time and resources required to manage multiple access points.
- Performance improvement: CAPsMAN ensures equal distribution of wireless channels and minimizes interference, resulting in improved Wi-Fi network performance.
- Greater security: Centralized management of authentication and security policies helps protect the network against unauthorized access and security threats.
- Better User Experience: Users experience more stable connectivity and smooth transition between access points, improving their overall experience.
CAPsMAN Basic Configuration
CAPsMAN configuration may vary depending on network topology and specific requirements, but here is an overview of the basic steps:
- Enable CAPsMAN: Activate the CAPsMAN feature on your MikroTik RouterOS router.
- Configure Controllers (Controlled Interfaces): Define the interfaces that will serve as CAPsMAN controllers, typically the Ethernet interfaces connected to the CAPs.
- Define CAPs: Configure the access points (CAPs) you want to manage with CAPsMAN. Assign the corresponding WLAN interfaces and define configuration policies.
- Configure Rules and Profiles: Set rules and profiles to define security policies, channel assignment, QoS, and other parameters.
- Enable CAPsMAN in CAPs: Finally, enable CAPsMAN on the CAPs and set the CAPsMAN controller address.
Example 1: CAPsMAN Basic Configuration
- Enable CAPsMAN Service
/caps-man manager set enabled=yes
- Set up a Channel
/caps-man channel add name=channel-1 frequency=2412 band=2ghz-b/g/n
- Create a Configuration Profile
/caps-man configuration add name=cfg1 ssid=myNetwork mode=ap channel=channel-1 datapath.bridge=local
- Apply Configuration to CAPs
/caps-man interface add configuration=cfg1 name=caps1
/interface wireless cap set caps-man-addresses=192.168.88.1 discovery-interfaces=ether1
In this example, CAPsMAN is enabled, a channel is configured, and a configuration profile is created with a specific SSID. This configuration is then applied to the CAPs.
Example 2: Advanced Configuration with Authentication and Security
- Enable CAPsMAN
/caps-man manager set enabled=yes
- Configure Channel with Enhanced Security
/caps-man channel add name=channel-2 frequency=5180 band=5ghz-a/n/ac
- Establish a Configuration Profile with WPA2
/caps-man configuration add name=cfg2 ssid=mySecureNetwork mode=ap channel=channel-2 security.authentication-types=wpa2-psk security.encryption=aes-ccm security.passphrase=MyStrongPassword
- Apply Configuration to CAPs
/caps-man interface add configuration=cfg2 name=caps2
/interface wireless cap set caps-man-addresses=192.168.88.1 discovery-interfaces=ether1
In this second example, a channel in the 5 GHz band is configured with WPA2 security, including a strong password for the network. The created configuration profile is then applied to the CAPs.
Conclusion
CAPsMAN by MikroTik RouterOS is an essential tool for efficient management of wireless networks, whether in commercial or residential environments.
It offers configuration centralization, improved security, optimized performance, and a more satisfying user experience.
By leveraging the capabilities of CAPsMAN, administrators can simplify wireless network management and ensure optimal performance of their Wi-Fi infrastructures.
