Cisco ASA syslog 格式说明

在哪里可以找到 Cisco ASA syslog 格式描述？日志示例：

我只找到了这个文档来自思科，其中没有关于“Message_text”字段的解释。

答案1

看一下这个，例如使用 %ASA-4-106023 作为索引： http://www.cisco.com/en/US/docs/security/asa/asa80/system/message/logmsgs.html

错误消息 %PIX|ASA-4-106023：拒绝协议 src [interface_name:source_address/source_port] dst interface_name:dest_address/dest_port [type {string}, code {code}] by access_group acl_ID

解释：ACL 拒绝了一个真实的 IP 数据包。即使您没有为 ACL 启用日志选项，也会显示此消息。

建议的操作：如果消息持续来自同一源地址，则消息可能表明存在足迹或端口扫描尝试。请联系远程主机管理员。

如果你问助记符是什么，这里有一个解释这里。
