asix electronics corporation 6 ax886 55 p 5 - port 10/100/1000base - t ethernet switch 1.0 ax88655 overview 1.1 general description the ax88655 gigabit switch controller supports five 10/100/1000 mbps ports in wire - speed operation. the ax88655 gigabit switch controller provides five 10/100/1000 ethernet ports with gmii/mii interface. for each ports, the ax88655 supports gmii (802.3ab) interface with full - duplex operation at gigabit speed, full - or half - duplex operation at 10/100 mbps speed and polls the status of phys with an embedded mpu. embedded 128k bytes sram as a packet buffer operates with an internal 90 mhz clock. for efficient utilization of the packet buffer, there are 1024 128 - byte page - links totally in the buffer. the device supports 4k internal mac addresses which are shared by all ports with an embedded 32k byte ssram. the learning/routing engine is implemented with a two - way hash/linear algorithm to reduce possibility of routing collision. basically the ax88655 supports non - blocking wire speed forwarding rate and no head - of - line (hol) blocking issue. the ax88655 provi des two flow - control mechanisms to avoid loss of data: an optional jamming based backpressure flow control in the half - duplex operation and ieee 802.3x in the full - duplex mode. to support quality of service (qos), each output port has two priority queues and their assignment can be based on the 802.1p priority field or port - pair setting. each output port retrieves the frames from the shared buffer based on queuing and sends them to the transmitting (tx) fifo. 1.2 ax88655 block diagram fig - 1 ax88655 block diagram 10/100/1000 mac 10/100/1000 mac 10/100/1000 mac high speed switch fabric routing /learning engine buffer manager packe t buffer general purpose i/o interface (gpio) gmii phy address look - up table 10/100/1000 mac 10/100/1000 mac eeprom interface gmii phy gmii phy gmii phy gmii phy gpio configuration logic

asix electronics corporation 12 ax886 55 p 5 - port 10/100/1000base - t ethernet switch 3.0 functional description 3.1 introduction in general, the ax88655 device is a highly integrated layer 2 switch. it supports five 10/100/1000 ports with on - chip macs. it also supports integrated switching logic, packet queuing memory and packet storage memory. the ax88655 is capable of routing - and - forwarding packets at wire spe ed on all ports regardless of packet size. it is a low cost solution for five ports gigabit ethernet backbone switch design. no cpu interface is required; after power on reset, ax88655 provide an auto load configuration setting function through a 2 wire s erial eeprom interface to access external eeprom device, and ax88655 can easily be configured to support trunking, qos, ieee 802.3x flow control threshold setting, broadcast storm control ...etc functions. an overview of ax88658?s major functional blocks is shown in fig - 1 . 3.2 packet filtering and forwarding process the switch use simple store - and - forward algorithm as packet switching method. after receives incoming packets, the packets will be stored to the embedded memory first. the ax88655 searches in the address - lookup table with da of the packet. the packet will be forward to its destination port, if this packet?s da hits; otherwise this packet will be broadcasted. of course, only good packets will be forward. conditions of good packets are below: 1. crc is correct. 2. 64 bytes < packetlength < 1518/1522 bytes 3. not local packets, that is, it is a local packets if its sourceport is its destinatio n port. 4. not pause or other control packets. 5. not the same trunking group. 3.3 mac address routing, learning and aging process the switch supports 4k mac entries for switching. two - way dynamic address learning is performed by each good unicast packet is completely received . a nd linear/xor hash algorithm of the static address learning is achieved by eeprom configuration. o n the other hand, the routing process is performed whenever the packet?s da is captured. if the da can not get a hit result, the packet is going to broadcast. only the learned address entries are scheduled in the aging machine. if one station does not tra nsmit any packet for a period of time, the belonging mac address will be kicked out from the address table. the aging out time can be program automatically through the eeprom configuration. (default value is 300 seconds) 3.4 full duplex 802.3x flow contr ol in full duplex mode, ax88655 supports the standard flow control mechanism defined in ieee 802.3x standard. it enables the stopping of remote node transmissions via a pause frame information interaction. when space of the packet buffer is less than the i nitialization setting threshold value, ax88655 will send out a pause - on packet with pause time equal to ? x fff? to stop the remote node transmission. and then ax88655 will send out a pause - off packet with pause time equal to zero to inform the remote node t o retransmit packet if has enough space to receive packets. 3.5 half duplex back pressure control in half duplex mode, ax88655 provide a backpressure control mechanism to avoid dropping packets during network conjection situation. when space of the packet buffer is less than the initialization setting threshold value, ax88655 will send a jam pattern in the input port when it senses an incoming packet, thus force a collision to make the remote node transmission back off and will effectively avoid dropping p ackets. and then ax88655 will not send out a jam packet any more if has enough space to receive one packet. 3.6 mii polling the ax88655 supports phy management through the serial mdio/mdc interface. that is, the ax88655 access related
asix electronics corporation 13 ax886 55 p 5 - port 10/100/1000base - t ethernet switch register of phys v ia mdio/mdc interface after power on reset. the ax88655 will periodically and continuously poll and update the link status and link partner?s ability which include speed, duplex mode, and 802.3x flow control capable status of the connected phy devices thro ugh mdio/mdc serial interface. 3. 7 port - based qos: port - pair ax88655 provides 4 port - pairs for bandwidth management. users can assign any two ports as one port - pair with internal registers basically. any packets will put the high priority queue of the po rt - pair when send the packets each other. that is, two ports of each port - pair will obtain more bandwidth than other ports when congestion. in addition, one port can be as the highest priority port if one all_bit of a port - pair is active. that is, user ca n assign format of the port - pair as oneport - to - all and every packets of the oneport will put in the high priority transmit queue of other ports.
