NINE-PORT MANAGED 10/100 SWITCH WITH IEEE 802.1/P/X/Q VLAN
Sixth-generation L2+ Fast Ethernet switch on a chip
The BCM5338M integrates:
• Eight transceivers (IEEE 802.3u compliant)
• Nine medium access controllers (MACs) (IEEE 802.3x
compliant)
• One port can be assigned as a WAN port
• 256-KB memory for packet buffer and control
• Non-blocking switch fabric supports up to 24 ports
Cascades to 36 ports through a 3.2-Gbps expansion port
Stack to 48 ports with a 200-Mbps turbo MII port
IEEE 802.1p QoS packet classification with four priority
queues
IEEE 802.1Q based VLAN with 512 entries
Supports IEEE 802.1x EAPOL higher layer protocol
MAC based trunking with automatic link failover
Programmable per port storm control and rate control
Port protection allows traffic aggregation to assigned port
4K MAC addresses with automatic learning and aging
Per port programmable MAC address locking
Programmable per port flow control and back pressure
Buffer repeater mode
MII or reversed MII
MDC/MDIO and SPI interfaces
Port mirroring and IGMP layer2/3 snooping
MIB Autocast
® function
DTE (power over Ethernet)
Hardware support for SNMP, RMON, and STP
Internal oscillator simplifies design and reduces cost
JTAG
3.3V and 1.8V, and typical power consumption is less than 2W
BCM5328M pin-to-pin compatible 208-pin MQFP package
Enables a new generation of affordable 10/100 switches with
highest integration of enhanced L2+ features
Uses field-proven industry-standard 10BASE-T/100BASE-TX
(100BASE-FX compatible) Fast Ethernet transceivers—
lowering overall system interoperability and reliability risks
IEEE 802.1Q based VLAN and flexible priority queues
mapped to selectable protocols such as IEEE 802.1p, Diffserv,
ToS, and CoS, enable the switch to be designed to a wide
variety of applications for multimedia and data traffic
Supports port based Extensible Authentication Protocol over
LAN in four application modes; forwards only EAPOL frames
to the CPU for authentication and allows secure mode traffic
filtering
Supports IEEE 802.1ad aggregation/port trunking
Per port storm control of broadcast, multicast, and unlearned
unicast traffic
Flexible per port ingress/egress rate control with minimum
resolution of 48 Kbps for better traffic management
MAC address locking enhances security control
MII port supports additional 100TX/FX
Optional reversed MII port connects directly to an IEEE 802.3
compliant MAC
Access to all internal registers through SPI or MDC/MDIO
interfaces
Low-cost management using the on-chip MIB registers allows
the collection and transmission of basic management statistics
for each port
Switch management features:
• Low-cost MIB Autocast function
• Hardware support for Simple Network Management Protocol
(SNMP), remote network monitoring (RMON), IEEE 802.1d
spanning tree protocol, IEEE 802.1s multiple spanning tree (up
to 32), and IEEE 802.1w rapid spanning tree protocol
