An L2/L3 switching architecture with BGP and OSPF routing capabilities determines this platform's role in modern enterprise data center and campus networks. The MikroTik CRS328-4C-20S-4S+RM is a 28-port Cloud Router Switch engineered for network engineers and IT infrastructure teams deploying scalable, high-density Ethernet switching with integrated routing intelligence. Built on the Marvell Prestera 98DX8212 switch chip and powered by a Marvell 88F7040 quad-core ARM Cortex-A72 processor running at 1.0 GHz, this 1U rackmount unit delivers 336 Gbps switching capacity and 250 Mpps forwarding performance across its full port complement.
Port density and uplink flexibility define the CRS328-4C-20S-4S+RM specification: 20 dedicated 1G SFP ports provide high-speed fiber connectivity, complemented by 4 combo ports supporting either 1G SFP or RJ45 operation, and 4 × 10G SFP+ uplink ports for tier-to-tier interconnect. The unit runs MikroTik RouterOS with support for SwOS for pure switching deployments, offers 1 GB DDR4 RAM and 16 MB NAND flash, and supports IEEE 802.1Q VLAN tagging up to 4096 VLANs, STP/RSTP/MSTP resilience, and IEEE 802.3ad LACP link aggregation. Management options include serial console, out-of-band RJ45 management, SSH, Telnet, Winbox, WebFig, REST API, and SNMP—enabling seamless integration into enterprise monitoring and orchestration frameworks.
