三、算法或核心技术思考体会：
1、当由用户模式进入特权模式时，应该输入的密码是abcde还是edcba？
为什么？
edcba。
因为特权密码是edcba.
2、在配置文件running-config中口令和密码的显示有什么不同？
enablesecret5$sdf$6978yhg$jnb76sd
enablepasswordabcde
一个是控制台口令，一个是远程登陆口令。
3、如果把PC1的IP地址改为192.168.1.21/24，验证它和PC2能否连通，为什么？
不可以ping通，与默认网关不匹配。
4、通过?
命令查看shmac命令的完整写法是什么？
showmacaddress
5、为交换机配置IP地址有什么用途？
使用此IP地址登陆交换机进行管理和设置。
