上周四，我给合作伙伴培训，问到谁玩儿过思科设备40G的以太网接口？回答是，没有。
只好自己上网找找。
发现了这篇文章：
How 40 Gigabit Ethernet on Cisco Catalyst 6500 Series Switches works?
https://www.slideshare.net/irisdan/how-40-gigabit-ethernet-on-cisco-catalyst-6500-series-switches-works
题外话，Slideshare 也是不错的共享文档平台，而且有字幕，说明等。不错。

所以40G以太网的接口名称是： FortyGigabitEthernet
TenGigabitEthernet 是10G以太网的接口名字。
FourX ， 是英文+罗马数字吗？想起当年的CFP，的C！
FourX converter for 10 Gigabit Ethernet SFP+， 40G的接口和10G接口的转换卡。 不错。1分4 ，4合一。

To configure 40-G port 4 on a standalone device, enter this command:
Device(config)# interface fortygigabitethernet1/0/4

以太网接口是: Fo1/1/1
而且在Catalyst 9300 上面还可以执行python 命令：

在Catalyst 9300 的 IOS XE上还可以运行 Linux 虚机。
