BCM5324M SINGLE-CHIP L2+ MANAGED SWITCH WITH 24 10/100 PORTS + 2 GbE PORTS FEATURES SUMMARY OF BENEFITS Seventh-generation ROBO L2+ 24FE + 2GE switch with two The BCM5324M includes: GMII/RGMII/TBI interfaces - 24 10/100 transceivers for TX/FX - 24 media access controllers Twenty-four fully integrated 10/100 PHYs with support of Advanced Cable Diagnostics in the Broadcom PHY technology - Two Gigabit media access controllers - 3 Mb total of packet buffer and control memory QoS packet classification supports four priority queues - Non-blocking switch fabric supports up to 24 FE+2 GE Port-based VLAN and 802.1Q VLAN with 4k entries ports Supports traffic aggregation via double tagging Advanced Cable Diagnostics minimize the need for expensive cable troubleshooting equipment. Spanning Tree (IEEE 802.1D/1s/1w) Enables a new generation of lower cost FE switches with the MAC-based trunking with automatic link failover highest integration of enhanced L2+ features and maximum connectivity. Port mirroring Optimized for WebSmart managed switch design. IGMP snooping Layer2/3 802.1Q VLAN allows segmentation of network into smaller Over 70 MIB counters for per port management statistics broadcast domains to preserve bandwidth and increase network security. Up to 24 Static Secure MAC addresses per port Four flexible Class of Service (CoS) queues per port assures the lowest latency to high-priority traffic. This enables the Programmable Broadcast, Multicast, and Unknown Unicast switch to support a wide variety of delay sensitive video and storm control audio multicast applications. Per port bandwidth/rate control IEEE 802.3ad link aggregation increases effective bandwidth 8K MAC addresses with automatic learning and aging and provides redundancy of a link. IEEE 802.1X Extensive Authentication Protocol over LAN Protected port (EAPOL) plus MAC address locking enhances network port security. Multicast address table for 256 entries th Storm and bandwidth/rate control provide better traffic 25 FE port via MII or reversed MII mode for management profile management. MDC/MDIO and SPI interfaces Access to all internal registers through SPI or MDC/MDIO interfaces. Internal oscillator simplifies design and reduces cost Hardware support for implementing SNMP and RMON.

Circuit Rate Control MII / RvMII Interface MAC SPI / CPU CPU Interface Interface BCM5324M Block Diagram BCM5324M is designed based on the field-proven industry leader CoS queues based on the Port ID, the MAC address, the 802.1p priority ROBOSwitch. This device combines all the functions of a high-speed field in layer 2, the TOS field in IPv4 or the DiffServ field in IPv6 switch system including packet buffers, PHY transceivers, media access headers. Together with other advanced features, such as 802.1x EAPOL controllers, address management, and a non-blocking switch fabric into protocol filtering, Port bandwidth/rate control, MAC address locking a single 0.13 m CMOS device. It complies with IEEE 802.3 and IGMP snooping at Layer2 and Layer3 allow system vendors to build specifications, including the MAC control PAUSE frame and auto- advanced L2+ switch systems for the multitenant/multidweller unit negotiation subsections, providing interoperability with all industry- (MDU/MTU) markets. standard Ethernet, Fast Ethernet and Gigabit Ethernet devices. The BCM5324M family of switches is optimized for WebSmart and L2 BCM5324M is the industry first Ethernet to integrate twenty-four full- managed designs. The new level of integration brings L2 manageable to duplex 10BASE-T/100BASE-TX/FX Fast Ethernet transceivers. Each SMB switches at an affordable price. Single chip replaces the typical 3- transceiver incorporates the Broadcom PHY Advance Cable Diagnostic or 4 chip solutions in the market today. technology, which can detect cable shorts as well as open and measure For Network Management, the BCM5324M includes 70+ on-chip MIB the cable length. BCM5324M also supports two GMII/RGMII/TBI counters to collect receive and transmit statistics from each port for interfaces, providing flexible 10/100/1000BASE-TX and fiber supporting the Etherlike MIB, Bridge MIB, MIB II (interfaces) and the connectivity. RMON MIB (Groups 1, 2, 3, 9). BCM5324M supports 8K MAC addresses, 4K VLAN addresses and Product ordering information: stores up to 256 multicast addresses including IP multicast. BCM5324M BCM5324M (24FE+2G) also supports 802.1d Spanning Tree, 802.1s Multiple STP, 802.1w Rapid BCM5322M (24FE+2MII) STP, and flexible ingress and egress checking rules for VLAN BCM5321M (16FE+2G) processing. BCM5320M (8FE+2G) BCM5324M supports up to four CoS queues per egress port, ideal for delay sensitive multimedia applications.
