其中说道: The QSFP28 port 接口?啥意思?
The Cisco Nexus 3232C has 32 QSFP28 ports. 有32 个QSFP28接口?为什么叫 QSFP28?
只好Google 呗。

the alphabet soup --->以字母简称命名
The [CFP]- "C" for 100, and FP for "Form factor, Pluggable." , 当年我考了很多人C是什么意思。呵呵。应该是罗马数字。有兴趣的读者自己谷歌吧。
The QSFP28 module has an upgraded electrical interface to support signaling up to 28 Gbps signals, yet keeps all of the physical dimensions of its predecessor.
