"媒体独立"表明在不对MAC硬件重新设计或替换的情况下,任何类型的PHY设备都可以正常工作。802.3协议最多支持32个PHY,但有一定的限制:要符合协议要求的connector特性。MII接口如下图所示: 提到MII,就有可能涉及到RS,PLS,STA等名词术语,下面讲一下他们之间对应的关系。 所谓RS即Reconciliation sublayer,它...
以太网帧的格式为:前导符+开始位+目的mac地址+源mac地址+类型/长度+数据+padding(optional)+32bitCRC。如果有vlan,则要在类型/长度后面加上2个字节的vlan tag,其中12bit来表示vlan id,另外4bit表示数据的优先级! GMII(Gigabit MII) GMII是千兆网的MII接口,这个也有相应的RGMII接口,表示简化了的GMII接口...

也就是说这种情况下的PMD是光模块,nPPI就必然是一种chip to module间的接口,这也是IEEE802.3标准与OIF_CEI标准兼容的地方之一。nPPI按照通道数量的不同分成两种。 XLPPI:40 Gigabit Parallel Physcial Interface,4条lane,每条lane的数率是10.3125Gbps; CPPI:100Gigabit Parallel Physcial Interface,10条lane,每条lane...

( why else would you build a 12 port ethernet switch! ) Not sure if it's going to end up cheaper, but you could use a gigabit transformer module for two ports. You'll also be able to use the 4th port on the inner switch by routing it to another connector. (Just leave the spot...
