AL102A Advance Information
AL102A Overview
AL102A provides eight 10/100 Mbit/s Ethernet ports. Each port supports both Mbit/s data rate. operation mode auto-negotiated PHY. ports full-duplex capable. device supports VLAN workgroup segment switching applications. AL102A also supports trunking applications. chip provides optional load balancing schemes, explicit dynamic. With trunking, possible group four full-duplex links together form single Mbit/s link. Data received from interface stored external memory buffer. AL102A utilizes cost effective SGRAM provide 8-Mbit 16-Mbit buffer memory. During transmission, data obtained from buffer memory routed destination port. event collision during half-duplex operations, control will back retransmit accordance IEEE 802.3 specification. AL102A provides flow control methods. half-duplex operations, optional jamming based flow control (also known backpressure) available prevent loss data. With this method flow control, switch will generate signal when receive-buffer full. sending station will transmit until line clear. full-duplex mode, AL102A utilizes IEEE 802.3x flow control mechanism. ports support multiple addresses. switch chip supports addresses internally. These addresses shared among eight ports. initialization configuration switch programmed external EEPROM. unmanaged switch design, required. Field reconfiguration achieved using parallel interface reprogram EEPROM. AL102A supports port-based VLAN. VLAN register used configure destination ports multicast broadcast frames. device also provides levels security intrusion protection. Security implemented port basis. AL102A operates only store forward mode. entire frame checked error. Frames with errors automatically filtered will forwarded destination port. Other features include port monitoring broadcast storm throttling.
