IP1717 16+1 ports Ethernet Switch Co*oller with Octal-PHYs   General Description : The IP1717 is a cost effective and fully integrated single chip. It integrates a 17-port switch co*oller, an octal PHY transceiver and SSRAM. Each of PHY transceiver complies with 802.3u specification and HP-license Auto MDI/MDIX.                                The IP1717 also provides a 3S-MII interface to connect an octal PHY for a 16-port dumb switch application and a MII interface for a smart/management switch application. In addition, it supports full smart switch functions, including IGMP snooping, 4 priority queues, TOS, TCP/UDP port number priority, 802.1Q VLAN, port security, protocol filter/forwarding and bandwidth co*ol.
