求这段配置的详细解释:核心交换机S5560-30C-EI 的一段配置,其中的established,icmp-type echo, icmp-type echo-reply, eq bootps,eq bootpc不清楚含义??

最佳答案
TCP连接建立标识 | 定义对TCP连接报文的处理规则 | TCP协议特有的参数,用于定义TCP报文中ACK或RST标志位为1的报文 |
当protocol为icmpv6(58)时,用户还可配置如表1-14所示的规则信息参数。
表1-14 ICMPv6特有的规则信息参数
ICMPv6报文的消息类型和消息码 | 指定本规则中ICMPv6报文的消息类型和消息码信息 | icmp6-type:ICMPv6消息类型,取值范围为0~255 icmp6-code:ICMPv6消息码,取值范围为0~255 icmp6-message:ICMPv6消息名称。可以输入的ICMPv6消息名称,及其与消息类型和消息码的对应关系如表1-15所示 |
表1-15 ICMPv6消息名称与消息类型和消息码的对应关系
ICMPv6消息名称 | ICMPv6消息类型 | ICMPv6消息码 |
这条rule里匹配去往目的172.16.80.0 0.0.0.255的TCP连接报文
