Q:关于802.1q描述正确的3项
A：正确,native vlan默认是不打标的,这就是规定
B：错误,port-security只能用在access端口,如果在trunk上尝试的话会收到"you cannot enable port security on a trunk"的错误信息
C：正确,看链接,部分支持
D：错误,与双工、速度设置无关
E：正确,802.1q trunk链路的两端都必须拥有相同的native vlan(本征vlan),如果强制设置成不相同也可以,但是会报错,而且安全性和一些features会出现不正常的现象
sorry,我不是翻译,我只是将答案分析解释给你听,因为做这一行,英文是必须的
