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