RvMII, MII, or GMII additional port for management
EEPROM, SPI, MDC/MDIO, or EB Bus Interfaces
Hardware and software reset
Provides per port 70+ MIB counters with MIB Snapshot capability
Jumbo frame support up to 2048 bytes
JTAG
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.
Embedded 1.8V and 1.2V regulators, typical power consumption:
5W
