It belongs to the RB3011 series, which is known for its ARM-based architecture, enhanced processing capabilities, and broad feature set via RouterOS.The RB3011UiAS-RM comes equipped with two groups of five Gigabit Ethernet ports, one SFP cage for fiber connectivity, and a USB 3.0 port for external storage or 4G modem use. Housed in a 1U rackmount case, it is tailored for environments that demand high uptime, efficient throughput, and advanced configuration options.Key Features of MikroTik RB3011UiAS-RM10x Gigabit Ethernet Ports: Split into two switch groups for flexibility and segmentation.SFP Port: For fiber uplinks or additional network interface options.USB 3.0 Port: Enables you to connect external storage, 3G/4G modems, or other peripherals.1U Rackmount Case: Ideal for data centers and server rooms with standard rack infrastructure.LCD Display: Allows quick monitoring of device status directly from the unit.RouterOS Level 5 License: Grants access to advanced routing, firewall, and VPN capabilities.1.4 GHz Dual-Core ARM CPU: Provides strong performance for routing, firewall, and traffic management tasks.1 GB RAM: Ensures smooth operation under heavy loads or with multiple active services.Benefits of Using RB3011UiAS-RMHigh Performance for SMBsWith its powerful dual-core ARM CPU and 1GB of RAM, the RB3011 is more than capable of handling complex routing scenarios, including VPN, NAT, and firewall rules for dozens or even hundreds of users.Versatile Port ConfigurationTen Gigabit Ethernet ports give you the flexibility to manage different LAN segments, VLANs, or network zones without additional hardware.Fiber ReadyThe built-in SFP port supports fiber connectivity for high-speed uplinks or WAN redundancy.Advanced OS FeaturesThanks to RouterOS, you get enterprise-grade features such as traffic shaping, hotspot functionality, PPPoE server, firewall, and more.Cost-Effective UpgradeCompared to other enterprise routers, the MikroTik RB3011UiAS-RM Ethernet Router delivers great value for money.Use Cases of the MikroTik RB3011UiAS-RMOffices with Multiple DepartmentsSegment the internal network by department using port-based VLANs and firewall policies.Data Centers and Server RoomsTake advantage of rackmount form factor, SFP port for fiber uplinks, and remote management via RouterOS.Hotels and HospitalityUse MikroTik’s built-in hotspot manager to deliver Wi-Fi with user authentication and bandwidth control.Retail NetworksCombine wired terminals and wireless networks using RB3011’s high port count and integrated management.How to Optimize RouterOS on RB30111. Upgrade to the Latest Stable VersionAlways start by updating your device to the latest RouterOS stable release:Go to System > PackagesClick Check for UpdatesChoose the Stable channel and apply the updateReboot the router2. Enable FastTrack for NATFastTrack drastically improves throughput for normal internet traffic:Go to IP > Firewall > Filter RulesAdd a rule at the top of your list:Chain: forwardConnection state: established, relatedAction: fasttrack connection⚠️ Don’t use FastTrack if you need detailed traffic accounting or QoS.3. Use Bridge Filtering WiselyIf you’re using a bridge with multiple ports:Use hardware offloading where available (check with /interface bridge port print)Avoid complex filtering in the bridge to reduce CPU load4. Disable Unused ServicesTurn off services you don’t use to reduce attack surface and free resources:Go to IP > ServicesDisable: FTP, Telnet, and other unused servicesOnly keep Winbox and SSH (with strong passwords)5. Tune Connection TrackingIf you’re not using firewall tracking for certain traffic types:Go to IP > Firewall > ConnectionsAdjust timeout values or disable tracking on specific interfaces (use mangle rules with connection tracking disabled)6. Limit Logging OutputExcessive logging can slow down the system:Go to System > LoggingDisable or reduce info, debug, or firewall logs unless necessary7. Monitor ResourcesUse System > Resources and Tools > Profile to identify bottlenecks:Look for high CPU loadsIf a specific process (like firewall or dns) consumes too much, optimize related rules or configurations8. Use Address Lists for Efficient Firewall RulesInstead of many rules with single IPs:Group IPs in Address ListsReference the list in a single rule to reduce processing time9. Optimize Queues (Optional)For traffic shaping:Use Simple Queues only for basic needsFor better control, set up Queue Trees but avoid using them if you’re relying on FastTrack10. Secure Remote AccessChange the default Winbox portLimit access to trusted IP rangesEnable 2FA on Winbox (optional via external tools)Bonus: Use MikroTik ToolsTorch: For live traffic analysisPing & Traceroute: To test connectivityNetwatch: To trigger scripts on interface status changesThis setup ensures the RB3011UiAS-RM runs efficiently, securely, and performs optimally for both basic and advanced network environments.Managing Redundant Internet LinksWith RB3011, you can configure multiple WAN uplinks using ECMP or scripting for failover. Assign the primary link to port 1 and the secondary link to port 2, then use recursive routing checks to automatically switch if the main ISP fails.Comparison with Similar MikroTik RoutersFeatureRB3011UiAS-RMRB2011UiAS-RMRB5009UG S INCCR1009-7G-1C-1S CPU1.4 GHz Dual-Core ARM600 MHz MIPSQuad-Core ARM 1.4 GHzTilera 9-Core 1.2 GHzRAM1 GB128 MB1 GB2 GBEthernet Ports10x Gigabit5x Fast 5x Gigabit7x Gigabit7x GigabitSFP1x SFP1x SFP1x SFP 1x SFP USBUSB 3.0USB 2.0USB 3.0microUSBRackmountYesYesNoYesRouterOS LicenseLevel 5Level 5Level 5Level 6Price (Approx)Mid-rangeEntry-levelHigh-performanceHigher-endBest Use CaseSMB, Branch OfficesSmall OfficesISPs, Power UsersEnterprises, Data CentersTechnical Specifications TableSpecificationDetailsProduct NameMikroTik RB3011UiAS-RM Ethernet RouterCPUIPQ-8064 1.4 GHz dual-core ARMRAM1 GBStorage128 MB NANDEthernet Ports10 x 10/100/1000 Gigabit EthernetSFP Port1 x SFPUSB1 x USB 3.0LCD DisplayYesPower Input1x DC jack, 1x PoE-in (Passive)Power OutputPort 10 supports PoE-outMax Power ConsumptionUp to 30 WOperating SystemMikroTik RouterOS (Level 5)Dimensions443 x 92 x 44 mm (1U Rackmount)Operating Temperature-20°C to 60°CWeight1.1 kgFAQ – Frequently Asked QuestionsIs the RB3011UiAS-RM suitable for gigabit internet?Yes, it supports full Gigabit throughput and can handle high-speed plans with proper RouterOS configuration.Can I use this router with a fiber internet connection?Yes, via the SFP port, you can connect it directly to fiber modems or switches.What is the maximum number of users it can support?Depending on the configuration and traffic type, it can handle networks with 100 users.Is the RouterOS license upgradable?It comes with a Level 5 license, which covers most advanced features; Level 6 is optional but rarely needed.Can I mount the RB3011 in a 19-inch rack?Yes, it includes rack ears and is 1U rackmount ready.Does it support VPN services?Yes, it supports IPsec, PPTP, L2TP, SSTP, and OpenVPN.Can I manage the router remotely?Yes, through Winbox, WebFig, SSH, or API.What makes this router better than RB2011?It has a faster CPU, more RAM, USB 3.0, and better overall throughput.Is it compatible with MikroTik CAPsMAN for wireless control?Yes, it can act as a CAPsMAN controller for managing access points.ConclusionIf you’re searching for a powerful, flexible, and affordable router that fits seamlessly into your network rack and scales with your growing business, the MikroTik RB3011UiAS-RM Ethernet Router is a smart choice.
