DES-1218/DES-1226 10/100/1000 Mbps Ethernet Switch User’s Guide
The modules that can be installed include: the DES-122G 2 port 1000BASE-SX (SC type connector), DES-122GL 2 port 1000BASE-LX, DES-122GB 2 port GBIC, DES-122T 2 port 1000BASE-T, and DES-122GM 2 port 1000BASE-SX (MT-RJ type connector) modules.
This stand-alone Switch enables the network to use some of the most demanding multimedia and imaging applications concurrently with other user applications without creating bottlenecks. The built-in console interface can be used to configure the Switch’s settings for Priority Queuing, VLAN, and Port Trunk Groups, Port Monitoring and Port Speed.
Performance features
♦IEEE802.3 compliant
♦IEEE802.3u compliant
♦IEEE802.3z compliant
♦IEEE802.3ab compliant
♦IEEE802.1p Priority Queues
♦IEEE802.3x flow control in full duplex mode
♦NWay Auto-negotiation
♦Full and half-duplex for both 10Mbps and 100Mbps connections. The Gigabit Ethernet extension 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
♦Supports single-mode and multi-mode connections
♦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: 8 Megabytes (DES-1218 ) | 10 Megabytes (DES-1226) |
♦ | Broadcast storm control | |
♦ Supports 9 Port-based VLAN Groups | |
♦ | Port Trunking | |
♦ Back pressure in half-duplex | |
