将交换机fa0/1 -48加入vlan168并配置生成树协议

End with CNTL/Z. 3 keasysc2960-00(config)#int ran fa0/1 -48 4 keasysc2960-00(config-if-range)#sw mo acc 5 keasysc2960-00(config-if-range)#sw acc vlan 168 6 % Access VLAN does not exist. Creating vlan 168 7 keasysc2960-00(config-if-range)#spanning-tree portfast 8 %Warning: portfast should only be enabled on ports connected to a single 9 host. Connecting hubs, concentrators, switches, bridges, etc... to this 10 interface when portfast is enabled, can cause temporary bridging loops. 11 Use with CAUTION 12 13 %Portfast will be configured in 48 interfaces due to the range command 14 but will only have effect when the interfaces are in a non-trunking mode. 15 keasysc2960-00(config-if-range)#end
修改交换机千兆口为trunk口用于通信

配置远程telnet访问地址
1 keasysc2960-00#conf t 2 *Mar 1 00:04:27.730: %SYS-5-CONFIG_I: Configured from console by console 3 Enter configuration commands, one per line. End with CNTL/Z. 4 keasysc2960-00(config)#line vty 0 4 5 keasysc2960-00(config-line)#password k1234****(#此处为了保密省略真实密码#) 6 keasysc2960-00(config-line)#end
密码以明文显示
（Tips：enable password是明文保存， enable secret是密文保存 showrun中， enable password可以看到密码k12345678，enable secret 看到的是MD5加密后的密码）
1 keasysc2960-00#conf t 2 *Mar 1 00:04:49.281: %SYS-5-CONFIG_I: Configured from console by console 3 Enter configuration commands, one per line. End with CNTL/Z. 4 keasysc2960-00(config)#enable password k12345678 5 keasysc2960-00(config)#end
