port security
本帖最后由 sdwchow 于 2011-11-27 10:00 编辑（这个命令执行之后）如果帧被收到了，这个帧的mac地址将会被静态的设置保存在运行配置文件里。
实际上这样的话，是叫做动态获取，不是静态设置。 同意无尘1990的说法
Select the action that results from executing these commands.
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security mac-address sticky
A. A dynamically learned MAC address is saved in the startup-configuration file.
B. A dynamically learned MAC address is saved in the running-configuration file.
C. A dynamically learned MAC address is saved in the VLAN database.
D. Statically configured MAC addresses are saved in the startup-configuration file if frames from that
address are received.
E. Statically configured MAC addresses are saved in the running-configuration file if frames from that
address are received.
Answer: B
Explanation/Reference:
考点：考查交换机端口安全。sticky 关键字使静态配置和动态学习的mac方式优势相结合
A：把动态学习的mac保存到startup-config文件中，错误
B：把动态学习的mac保存到running-config文件中，正确
C：把动态学习的mac保存到vlan数据库中。错误。
D：如果接收到数据帧中包含静态配置的MAC地址，它将被保存在startup-config文件，错误
E:如果接收到数据帧中包含静态配置的MAC地址，它将被保存在running-config文件，错误
静态配置的直接保存在running-config里了。
