Overview
– 12 –
◆ Supports IEEE 802.3x flow control for full-duplex mode and backpressure
for half-duplex transfer mode.
◆ Non-blocking switching architecture that forwards and filters packets at full
wire-speed for maximum throughput.
◆ Supports MAC address auto-learning and auto-aging.
◆ The SMCGS1601 supports IEEE P802.3az Energy-Efficient Ethernet, which
can save up to 49% of power consumption.
◆ The SMCGS2401 supports Green Saving, which provides significant power
saving compared to non-green switches.
◆ The SMCGS1601 and SMCGS2401 support IEEE 802.1p QoS.
◆ LED indicators for monitoring power, link, speed and activity.
◆ Desktop and rack-mountable steel case.
◆ Internal power supply.
IEEE 802.1P QOS
The SMCGS1601 and SMCGS2401switches support 802.1p priority queuing
Quality of Service, which is an implementation of the IEEE 802.1p standard.
With the 802.1p QoS function, network traffic that requires high priority, such as
VoIP (Voice-over Internet Protocol), web browsing applications or video
conferencing, can be forwarded before other traffic. The switches have separate
hardware queues for each physical port, when packets are received with an
802.1p priority tag, they are sent to the appropriate output queue.
The illustration below shows how 802.1p priority queuing is implemented on the
switches.
