PCAP packet flow
By default, PCAP uses port mirroring. If a filter set is applied, flow mirroring is used. If further
filtering is required, PCAP software filters are applied. You can store captured packets in the
PCAP engine DRAM (PCAP00), on a PCMCIA device (or on external flash on the 8895 SF/
CPU), or on the network. You can then use FTP to download the stored packets to an offline
analyzer tool such as EtherReal or Sniffer Pro.
The following figure illustrates how to use the PCAP tool to configure PCAP filters and enable
them on ports.
