snmp-agent sys-info version v2c v3

6.H3C交换机配置密码复杂度

  1）举例：口令长度不低于12位，为数字、字母、特殊字符混合组合；密码有效期限为90天；输入密码次数过多后锁定。用户成功登录后10分钟内无任何操作，则断开该登录连接 。    

[CN-HBDHY-OA-5-1F407-DSW01]password-control enable  #开启密码策略
[CN-HBDHY-OA-5-1F407-DSW01]password-control length 12  #配置密码长度最短为12位
[CN-HBDHY-OA-5-1F407-DSW01]password-control composition type-number 3 type-length 1  #密码复杂度为包含3种类型
[CN-HBDHY-OA-5-1F407-DSW01]password-control login-attempt 5 exceed lock-time 5  #配置本地帐号连续输入错误密码的限制次数为5次，本地帐号锁定时间为5分钟
[CN-HBDHY-OA-5-1F407-DSW01]password-control aging 90  #配置密码失效时间为90天，默认即90天
[CN-HBDHY-OA-5-1F407-DSW01]password-control alert-before-expire 30  #配置密码过期前30天提醒
[CN-HBDHY-OA-5-1F407-DSW01]password-control history 5  #配置历史密码记录为5条
[CN-HBDHY-OA-5-1F407-DSW01]password-control login idle-time 0  #配置用户帐号的闲置时间为无限制
[CN-HBDHY-OA-5-1F407-DSW01]line vty 0 4
[CN-HBDHY-OA-5-1F407-DSW01-line-vty0-4]idle-timeout 10  #配置远程登录的闲置超时时间为为10分钟，默认为10分钟

  2）登录源IP限制  

[CN-HBDHY-OA-5-1F407-DSW01]acl number 2001 name sourlimit 
[CN-HBDHY-OA-5-1F407-DSW01-acl-basic-2001-sourlimit]rule 11 permit source 10.1.13.100 0
[CN-HBDHY-OA-5-1F407-DSW01-acl-basic-2001-sourlimit]rule 12 permit source 10.1.21.131 0
[CN-HBDHY-OA-5-1F407-DSW01-acl-basic-2001-sourlimit] rule 15 permit source 10.1.41.170 0
[CN-HBDHY-OA-5-1F407-DSW01-acl-basic-2001-sourlimit] rule 21 permit source 10.16.2.100 0

[CN-HBDHY-OA-5-1F407-DSW01]ssh server acl 2001

  3）管理员三权分开  

local-user admin class manage
 service-type ssh terminal
 authorization-attribute user-role level-15  #系统管理员分配管理级权限，即有全部权限
 authorization-attribute user-role network-operator

local-user audit class manage
 service-type ssh terminal
 authorization-attribute user-role level-1  #审计管理员分配监控级权限，只有部门查看权限
 undo authorization-attribute user-role network-operator
 password simple Abc123123#

local-user security class manage
 service-type ssh terminal
 authorization-attribute user-role level-2  #安全管理员分配配置级权限，有日常配置查看和修改的权限，不能进行FTP、文件下载、故障诊断等
 undo authorization-attribute user-role network-operator
 password simple Abc123123#

7.H3C交换机syslog配置

  0-7共八个级别，0最高，7最低

    

  1）保存到buffer 

  info-center logbuffer：开启Log信息向Log缓冲区的发送功能，此功能默认开启

  2）保存到syslog服务器  

[CN-HBDHY-OA-1-1F312-DSW01]info-center loghost source Vlanif348
[CN-HBDHY-OA-1-1F312-DSW01]info-center loghost 10.1.33.10 facility local0
