DHCP配置
DHCP服务器配置:
第一种方法:自动配置
路由上面配置网关,开启dhcp服务
[R1]dhcp enable
[R1-GigabitEthernet0/0/0]dhcp select interface
第二种方法:自定义配置
[R1]dhcp enable
[R1]ip pool ZDYDZCMZ 定义地址池名
[R1-ip-pool-ZDYDZCMZ]network 192.168.2.1 mask 24 宣告地址池网络
[R1-ip-pool-ZDYDZCMZ]gateway-list 192.168.2.1 定义网关
[R1-ip-pool-ZDYDZCMZ]dns-list 8.8.8.8 定义DNS
[R1-ip-pool-ZDYDZCMZ]lease day 3 hour 23 minute 59 租约时间
[R1-ip-pool-ZDYDZCMZ]excluded-ip-address 192.168.2.254 排除IP
[R1-ip-pool-ZDYDZCMZ]domain-name www.baidu.com 设置域名
[R1-ip-pool-ZDYDZCMZ]static-bind ip-address 192.168.2.10 mac-address 5489-98F1-701C IP与MAC绑定
[R1-GigabitEthernet0/0/1]dhcp select global DHCP全局配置模式
DHCP中继
第一步:实现全网互通
第二步:布置DHCP服务器
第三步:在SW1上启用DHCP中继
第四步:在SW2上启用snooping控制非法DHCP2服务器
[DHCP1]dhcp server ping packet 5 //在分配IP前检查是否有人占用IP
DHCP服务器跨网段分配:第三步
[SW1]dhcp enable
[SW1]dhcp server group huawei
[SW1-dhcp-server-group-huawei]dhcp-server 192.168.20.20
[SW1-dhcp-server-group-huawei]dhcp-server 192.168.20.30
[SW1-Vlanif10]dhcp select relay
[SW1-Vlanif10]dhcp relay server-select huawei
[SW1-Vlanif20]dhcp select relay
[SW1-Vlanif20]dhcp relay server-select huawei
[SW1-Vlanif30]dhcp select relay
[SW1-Vlanif30]dhcp relay server-select huawei
第四步
[SW2]dhcp enable
[SW2]dhcp snooping enable
[SW2-GigabitEthernet0/0/2]dhcp option82 insert enable
[SW2-GigabitEthernet0/0/2]dhcp snooping enable
[SW2-GigabitEthernet0/0/2]dhcp snooping trusted
[SW2-GigabitEthernet0/0/1]dhcp option82 insert enable
[SW2-GigabitEthernet0/0/1]dhcp snooping enable
[SW2-GigabitEthernet0/0/3]dhcp option82 insert enable
[SW2-GigabitEthernet0/0/3]dhcp snooping enable
FTP配置
FTP配置方法:
1,配置IP地址
2,AAA模式(认证,授权,//计费,FTP共享文件夹)
[server-aaa] local-user bbb password cipher 123456 //认证
[server-aaa] local-user bbb service-type ftp //ftp协议授权
[server-aaa] local-user bbb password cipher 123456 ftp-directory flash: //ftp的共享文件夹
注:user:bbb password:123456
3,FTP启用
[server]ftp server enable
4,验证
get 下载
put 上传
5,截取FTP用户名和密码
查看网络分层以及相关协议之间的关系(使用抓包工具)
Telnet配置
Telnet配置及登陆认证登陆标语:
[R1]user-interface console 0
[R1-ui-console0]authentication-mode password
提示:Please configure the login password (maximum length 16):mima 输入密码
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode password
Please configure the login password (maximum length 16):huawei
[R1-ui-vty0-4]user privilege level 3 设置访问级别:0-参观;1-监控;2-系统所有配置命令;3-管理员级别
