如何控制vty访问 0 1 2 3 4 Virtual ports (vty 0 through 4) Physical port (e0) (Telnet) 使用标准访问列表语句 用 access-class 命令应用访问列表 在所有vty通道上设置相同的限制条件 Router# e0 * Slide 1 of 1 Purpose: Emphasize: To filter incoming and outgoing telnet sessions to and from the router’s vty ports, standard access-list is used. If this is to block incoming telnet sessions into a router’s vty port, the standard access-list is used to match the source address of the host trying to telnet into the router’s vty port. If this is to block outgoing telnet sessions from the router’s vty ports to a host, the standard access-list is used to match the destination address of the host the router is trying to telnet into from its vty ports.
