It can be used to manage 400 clients, it can be more clients or less, depending on the type of configurations the RB4011 has and the bandwidth it is passing. It is recommended to monitor the computer's CPU so that it does not exceed 80%.

General Information

The number of clients that a MikroTik RB4011 device can handle depends on several factors, including the type of traffic, the specific configurations in use (such as firewall rules, quality of service (QoS), VPNs), and the nature of the applications that it supports. customers are using.

Since the RB4011 is a high-performance device designed for enterprise environments, it can handle a significant number of clients and network traffic simultaneously.

However, MikroTik does not provide a specific number of clients that the RB4011 can support, as this varies widely depending on the uses and configurations mentioned above. Generally speaking, the RB4011, with its 1.4 GHz quad-core CPU and 1 GB of RAM, is well equipped to handle:

• LAN connections for small to medium offices: It can work efficiently as the main router in office environments, supporting multiple subnets and VLANs.
• Wi-Fi access points: Although the RB4011 does not have built-in Wi-Fi (except for the RB4011iGS+5HacQ2HnD-IN model which does include Wi-Fi), it can handle traffic from numerous access points connected to it.
• VPN connections: Capable of handling multiple simultaneous VPN connections, although the exact number will depend on the traffic load and the type of VPN used.

For applications that require intensive processing (such as deep packet inspection, advanced content filtering, or high numbers of encrypted VPN connections), performance may be limited by CPU processing power.

Customer Capacity Considerations:

• Traffic and Use: A network with primarily web and email traffic will support more clients than a network with heavy use of video conferencing, VoIP, or large file transfers.
• Advanced Network Settings: Functions such as firewall, mangle, NAT, and QoS require more CPU resources, which can limit the number of clients that can be handled effectively.
• Performance Analysis: To determine actual capacity in a specific environment, consider performing performance tests under load, monitoring CPU usage, memory, and network throughput.

In summary, although the RB4011 is a powerful and capable device, the number of clients it can effectively manage will depend on the specific usage and network configuration.

For typical enterprise environments with moderate usage, the RB4011 can comfortably support tens to hundreds of clients, but planning and monitoring performance is recommended to ensure the device can meet specific network needs.
