BCM5348M
The BCM5348M includes:
Flexible TCAM-based ContentAware™ Classification technology
for affordable security and Access Control List
Double Tagging enables ISP applications.
Enables a new generation of lower cost FE switches with the
highest integration of enhanced L2+ features and maximum
connectivity.
Optimized for WebSuperSmart™ managed switch design.
802.1Q VLAN allows segmentation of network into smaller
broadcast domains to preserve bandwidth and increase network
security.
Four flexible Class of Service (CoS) queues per port ensure the
lowest latency to high-priority traffic. This enables the switch to
support a wide variety of delay-sensitive video and audio multicast
applications.
IEEE 802.3ad link aggregation increases effective bandwidth and
provides redundancy of a link.
IEEE 802.1X Extensive Authentication Protocol over LAN
(EAPOL) plus MAC address locking enhances network port
security.
Storm and Bandwidth/Rate Control provide better traffic profile
management.
Access to all internal registers through EB Bus, SPI, or MDC/
MDIO interfaces.
Hardware support for implementing SNMP and RMON.
Low-power consumption and embedded regulators allow simple
PCB design.
Server
- Twenty-four 10/100 transceivers for TX/FX
- Forty-eight media access controllers
- Five Gigabit media access controllers
- Four megabit total of packet buffer and control memory
- Nonblocking switch fabric supports up to 48 FE + 4 GbE ports

... Rapid STP, and flexible ingress and egress checking rules for VLAN processing. The BCM5348M 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 ...
