华为S5700交换机初始化和配置telnet，ssh用户方法
通过串口线配置S5700 的管理IP地址和网关，串口线接在交换机的console口，ip设置完成后网线接在ETH口：
[Quidway] interface Meth 0/0/1
[Quidway-Meth0/0/1]ip address x.x.x.x 255.255.255.0
[Quidway-Meth0/0/1]quit
[Quidway]ip route-static 0.0.0.0 0.0.0.0 x.x.x.x（gateway）
[Quidway]
设置telnet登录S5700(eg.设置用户名admin密码112233)：
[Quidway] user-interface vty 0 4
[Quidway-ui-vty0-4] authentication-mode aaa
[Quidway-ui-vty0-4]protocal inbound all
[Quidway-ui-vty0-4] user privilege level 15
[Quidway-ui-vty0-4]quit
[Quidway]telnet server enable
[Quidway] aaa
[Quidway-aaa] local-user admin password simple 112233
[Quidway-aaa] local-user admin service-type telnet
[Quidway-aaa] local-user admin privilege level 15
[Quidway-aaa] quit
设置SSH登录5700（eg.设置用户名admin密码112233）:
[Quidway]rsa local-key-pair create
The key name will be: Quidway_Host
% RSA keys defined for Quidway_Host already exist.
Confirm to replace them? [y/n]:y
The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
it will take a few minutes.
Input the bits in the modulus[default = 512]:
