本文档介绍NCS55xx(Fretta)框中的ICMP回应请求/应答数据包采用的路径。
IRPP
在接口上接收数据包,并将其传送到IRPP,在IRPP中将提取和处理前128个字节。因此,内部系统报头被预置。
ITM
数据包存储在DRAM/OCB中
ITPP
如果需要,重写系统报头(组播复制、端口镜像等)
数据包被拆分为信元,并负载均衡到交换矩阵
ERPP
接收信元并重组。前128个字节被提取并应用所有链路层过滤器、出口ACL、出口复制(组播)
ETPP/ETM
整个数据包存储在缓冲区中,直到数据包被调度出去。系统信头已删除。
端口终止:从网络接口/CPU/Recriculation接收的数据包
解析器:提取Ethertype、MAC地址,确定管道中后一阶段的偏移。
IRPP(线路层、VLAN传输)
链路层:过滤L2和源地址身份验证。
VLAN转换:我们映射数据包的逻辑接口。
NPU上复制RX Forus数据包。一个发送到活动RP,另一个发送到Stby RP
如果前缀邻接关系完成或是预路由数据包,则L3数据包会直接注入NPU
L3数据包会注入LC CPU,以防出现以下情况:
这些数据包从LC CPU注入到NPU:
