Brief
5-PORT GbE SWITCH WITH FIVE INTEGRATED PHYS AND PACKET BUFFER
FEATURES
• Highly integrated, non-blocking, 5-port 10/100/1000 switch
silicon that integrates:
• Five integrated 10/100/1000 PHYs
• One GMII/RGMII interface for an In-band Management Port
(IMP) for glueless connection to a CPU/management entity
• Serial EEPROM, MDC/MDIO, SPI, and Interrupt-to-CPU
Interface
• LoopDTech™ and CableChecker™ reduce network down
time and minimize support effort
• Broadcom’s patented LoopDTech technology for loop
detection without running spanning tree protocol
• Broadcom’s CableChecker enables advanced cable diagnostics
based on Broadcom’s convergence algorithm
• VLAN
• IEEE 802.1Q-based VLAN with 4K entries
• VLAN double-tagging (Q-in-Q)
• QoS
• Four selectable CoS per port: SP and WRR
• Port, MAC, 802.1P, and IPv4/IPv6 DSCP based QoS
• Performance
• 9 KB jumbo frame support—wirespeed performance for all
frame sizes
• 4K MAC addresses with automatic learning and aging
• Security
• IEEE 802.1x support for secure user authentication
• DoS prevention hardware
• Traffic control and network resiliency
• Storm control and port-based ingress/egress rate control
• Spanning tree support (rapid spanning tree and multiple
spanning trees—up to 16)
• BroadSync™ HD (AV bridging)
• Frame timer in MAC
• Real-time clock module for master clock generation and time
sync
• Management
• On-chip MIB counters to collect, receive, and transmit
statistics for each port. Hardware support for SNMP/MIBs and
RMON.
SUMMARY OF BENEFITS
• Provides a flexible solution for the cost-optimized board and
system designs
• Additional interfaces enable efficient designs for the branch
office switch applications. Flexible CPU interface allows the
BCM5395 to work with any CPU.
• Supports all types of client connections, including VoIP,
video, multimedia, and data. Proper priority can be assigned
to each traffic type to ensure guaranteed delivery of time-
sensitive packets and efficient use of network bandwidth.
• Access Control List (ACL) provides the security vehicle for
frame classification and filtering.
• IGMP and MLD snooping enables multicast switching
without expensive L3 multicast routing.
• BroadSync HD provides quality of service for audio-video
packs through Ethernet by adding end-to-end bandwidth
reservation, admission control, timing, and synchronization.
• Switch can be completely managed remotely using SNMP,
RMON, and OAM.
