Performance features
♦ 1000BASE-SX Gigabit Ethernet ports
♦ IEEE 802.3 compliant
♦ IEEE802.3u compliant
♦ IEEE802.3z compliant
♦ IEEE802.1p Priority Queues
♦ IEEE802.3x flow control in full duplex mode
♦ Full and half-duplex for both 10Mbps and 100Mbps connections. The 1000BASE-SX
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 a hub must take
place at half-duplex
♦ Store and forward switching scheme capability to support rate adaptation and
protocol conversion
♦ Auto-polarity detection and correction of incorrect polarity on the 10/100Mbps TX
ports
♦ Data forwarding rate 14,880 pps per port at 100% of wire-speed for 10Mbps speed
♦ Data forwarding rate 148,810 pps per port at 100% of wire-speed for 100Mbps
speed
♦ Data forwarding rate 1,488,100 pps per port at 100% of wire-speed for 1000Mbps
speed
♦ Data filtering rate eliminates all error packets, runts, etc. at 14,880 pps per port at
100% of wire-speed for 10Mbps speed
♦ Data filtering rate eliminates all error packets, runts, etc. at 148,810 pps per port
at 100% of wire-speed for 100Mbps speed
♦ Data filtering rate eliminates all error packets, runts, etc. at 1,488,100 pps per port
at 100% of wire-speed for 1000Mbps speed
♦ Forwarding 64 to1536 byte frames with correct CRC checksum
♦ Layer 2 switching based on MAC address
♦ Address handling : auto-learning , auto-aging
♦ Address table : Support addresses up to 17K
♦ Buffer size: 6 Megabytes
♦ Broadcast storm control
♦ Supports up to 9 Port-based VLAN Groups
♦ Port Trunking
♦ Back pressure in half-duplex
♦ Auto-negotiation (NWay) between 10Mbps/ 100Mbps, half-duplex or full duplex and
flow control for 10/100BASE-T ports.
♦ RS-232 DCE console port for setting port speed, duplex mode, and flow control of
the Switch via a connection to a console terminal.
Supports multimode fiber connections
