DES-3326S Layer 3 Fast Ethernet Switch User’s Guide
17
• Store and forward switching scheme.
• Full and half-duplex for both 10Mbps and 100Mbps
connections. The front-port Gigabit Ethernet module
operates at full-duplex only. Full-duplex allows the
switch port to simultaneously transmit and receive data,
and only works with connections to full-duplex capable
end stations and switches. Connections to hubs must
take place at half-duplex.
• Supports IEEE 802.3x flow control for full-duplex mode
ports.
• Supports Back-pressure flow control for half-duplex
mode ports.
• Auto-polarity detection and correction of incorrect
polarity on the transmit and receive twisted-pair at each
port.
• IEEE 802.3z compliant for all Gigabit ports (optional
module).
• IEEE 802.3x compliant Flow Control support for all
Gigabit ports (optional module).
• IEEE 802.3ab compliant for 1000BASE-T (Copper)
Gigabit ports (optional module).
• Data forwarding rate 14,880 pps per port at 100% of
wire-speed for 10Mbps speed.
• Data forwarding rate 148,800 pps per port at 100% of
wire-speed for 100Mbps speed.
• Data filtering rate eliminates all error packets, runts, etc.
at 14,880 pps per port at 100% of wire-speed for
10Mbps speed.
