核心交换机配置 目标：
a、为两个交换机分别设置管理、配置口及TELNET密码100.1和100.2; b、为两个核心交换机分别分配IP地址，即192.168.100.1、192.168.100.2；网关192.168.100.254。
c、在两个核心交换机上部署HSRP冗余网关协议；
d、设置三层交换机VLAN 间的通信，创建VLAN2,VLAN11,VLAN12?的虚接口，并配置虚接口VLAN2,VLAN11、VLAN12?相应的IP地址。
C3750X-24S-S1配置过程：
Switch>en ！进入特权模式命令 Switch#conf t ！进入全局模式命令 Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#enable password 100.1 ！配置特权模式密码为“100.1” Switch (config)#hostname C3750x-24s-s1 ！设置主机名为“C3750x-24s-s1”
22
C3750x-24s-s1(config)#interface vlan 1 ！
C3750x-24s-s1(config-if)#ip address 192.168.100.1 255.255.255.192
！设置交换机IP为192.168.100.1，用来管理交换机 C3750x-24s-s1(config-if)#no shutdown
