请问下工程师有关h3c s5560x-34s-ei 2个问题

以下是SSH配置的参考命令：

1、基础网络配置：

[H3C]vlan 10

[H3C-vlan10]quit

[H3C]int vlan 10

[H3C-Vlan-interface10]ip address 192.168.124.254 24

[H3C-Vlan-interface10]quit

[H3C]int gi 1/0/1

[H3C-GigabitEthernet1/0/1]port link-type access

[H3C-GigabitEthernet1/0/1]port access vlan 10

[H3C-GigabitEthernet1/0/1]quit

2、创建管理员账号，并赋予最高权限，仅允许SSH登录

[H3C]local-user admin

New local user added.

5、在VTY调用本地用户登录

[H3C]line vty 0 4

[H3C-line-vty0-4]authentication-mode scheme

[H3C-line-vty0-4]protocol inbound ssh

[H3C-line-vty0-4]quit
