配置完之后一般退出到特权模式,配置才生效。
1.将ios文件从电脑上拷入到交换机flash
首先要设置交换机的Ip地址,也就是interface vlan 1 之类的,保证这个ip 和你的tftp服务器ip在同一子网内。
Switch#copy tftp: flash:
Address or name of remote host [192.168.0.2]? //不管是拷入还是烤出,填写的都是你电脑的IP,也就是交换机对端(remote 远程)的IPSource filename [config.textx]? c2960s-universalk9-mz.122-56.SE3.binDestination filename [c2960s-universalk9-mz.122-56.SE3.bin]? Accessing tftp://192.168.0.2/c2960s-universalk9-mz.122-56.SE3.bin...Loading c2960s-universalk9-mz.122-56.SE3.bin from 192.168.0.2 (via Vlan1): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK - 10907578 bytes]10907578 bytes copied in 159.064 secs (68574 bytes/sec)
2.配置SSH登录到交换机
①启用aaa new-model 不启用,你试试、、、、、、
②配置hostname和ip domain-name:③ 配置登录用户名和密码(以本地认证为例)④ 配置SSH服务: aaa new-modelhostname Switchip domain-name tomax.comusername xxf password xmhcrypto key generate rsa 选择 ssh v2 atleast 768 bits size
Switch(config)#ip ssh version 2 选择ssh的版本
Switch(config)#ip ssh time-out 120 超时限定为120秒
Switch(config)#ip ssh authentication-retries 5 认证重试次数为5次
设置登录是否telnet 和SSH
Switch(config)#line vty 0 15
Switch(config-line)#transport input telnet ssh 同时支持telnet和 SSHSwitch(config-line)#transport input ssh 只支持SSH
3.设置clock
Switch#clock time GMT +8
Switch#clock set 15:45:00 23 September 2014
Switch#show clock
15:47:21.159 UTC Tue Sep 23 2014Core-Switch-1#conf t
Core-Switch-1(config)# clock timezone GMT +8
Core-Switch-1(config)#service timestamps debug datetime msec localtime show-timezone
Core-Switch-1(config)#service timestamps log datetime msec localtime show-timezone
Core-Switch-1(config)#exit
Core-Switch-1# clock set 13:51:00 Sep 7 2011
或通过NTP服务器时间同步:
Core-Switch-1#ntp server 192.168.0.254 key 8888 注:8888是指ntp服务器的Key值
Core-Switch-1#show ntp status
Core-Switch-1#wr
Core-Switch-1#sh log
Core-Switch-1#show clock
4.设置vty终端输出调试信息。
C3750A#terminal monitor
取消为
C3750A#terminal no monitor
