Networking 使用包跟踪器的ASA配置

我正在尝试配置以下网络

我无法从公用笔记本电脑打开

我能够从VLAN20 laptop0 ping到防火墙192.158.99.1

我有以下关于asa和多交换机的配置。 请让我知道我还需要做什么来完成这个网络

您正在仅管理模式下使用管理界面，因此只能使用此界面管理ASA。正如我所知，您不能从管理界面中删除“仅管理”选项

数据包跟踪器命令示例：

packet-tracer input outside tcp <laptop_ip> 148.12.56.68 80

上述配置将向所有日志消息添加时间戳，日志严重性级别为信息性级别，并缓冲16M日志消息

有关ASA日志记录的更多信息：

您可以找到有关日志严重性级别的更多信息：

要将日志消息发送到中心日志服务器，请执行以下操作：

logging host <asa_interface> <remote_log_server_ip> <protocol/port/>

我认为日志消息是解决问题的最佳朋友之一

我将管理界面从防火墙更改为千兆以太网。我在as上尝试了以下命令以显示跟踪：192.168.20.3是笔记本电脑0数据包跟踪程序输入的IP地址，在tcp 192.168.20.3 148.12.56.68 80之外，但它显示无效命令。数据包跟踪程序命令可以在特权EXEC模式下使用，因此您必须在

数据包跟踪程序

命令之前运行

命令。顺便说一下，我以为是公用笔记本电脑的IP地址，而不是内部地址。哦，好吧，我想我误解了。这是我在数据包追踪中的第一个网络。想学习ASA防火墙，我会用公共笔记本电脑检查。谢谢我在asa上以执行模式尝试了以下命令，但仍然显示无效命令：ciscoasa#tcp 172.16.1.100 148.12.56.68外部的数据包跟踪器输入在“^”标记处检测到80^%无效输入。西斯科阿萨#
