虚拟终端行 ACL

要限制 Telnet 和 SSH 到交换机的连接，请在虚拟终端线路上应用访问列表 (VTY)。

  1. 使用 permit 或 deny 筛选器创建 IPv4 或 IPv6 访问列表；例如：
    OS10(config)# ip access-list permit10
OS10(config-ipv4-acl)# permit ip 172.16.0.0 255.255.0.0 any
OS10(config-ipv4-acl)# exit
OS10(config)#
  2. 在 CONFIGURATION 模式下使用 line vty 命令进入 VTY 模式。
    OS10(config)# line vty
OS10(config-line-vty)#
  3. 在 LINE-VTY 模式下使用 {ip | ipv6} access-class access-list-name 命令将访问列表应用到 VTY 行。
    OS10(config-line-vty)# ip access-class permit10
查看 VTY ACL 配置
OS10(config-line-vty)# show configuration
!
line vty
 ip access-class permit10
 ipv6 access-class deny10
OS10(config-line-vty)#
