KSZ8999I規(guī)格書詳情
General Description
The KS8999 contains eight 10/100 physical layer transceivers, nine MAC (Media Access Control) units with an integrated layer 2 switch. The device runs in two modes. The first mode is an eight port integrated switch and the second is as a nine port switch with the ninth port available through an MII (Media Independent Interface).
Features

? Advanced Ethernet Switch with internal frame buffer
― 128K Byte of SRAM on chip for frame buffering
― 2.0Gbps high performance memory bandwidth
― Wire speed reception and transmission
― Integrated address look-up engine, supports 1K absolute MAC addresses
― Automatic address learning, address aging and address migration
? Advanced Switch Features
― Supports 802.1p priority and port based priority
― Supports port based VLAN
― Supports 1536 byte frame for VLAN tag
― Supports DiffServ priority, 802.1p based priority or port based priority o broadcast storm protection
? Proven transceiver technology for UTP and fiber operation
