In the example shown in Figure 203, the total length field value is 1500 bytes. Packets have been flagged with TCP issues or notifications (will not work if Analyze TCP Sequence Numbers is disabled in the TCP preferences) Total Length Field This field defines the length of the IP header and any valid data (this does not include any data link padding). ![]() This is how they will keep track of the sequence of data exchanged between them. 32 Initial Sequence Number The SYN packets synchronize the sequence numbers to ensure both sides know each other's starting sequence numbers (the Initial Sequence Number, or ISN). ![]() TCP Stream Index the Stream Index value in TCPĬonversations begins at 0 and counts up by 1 for each TCP conversation seen in the tra Routing Overview Pg. In this mode, the driver doesn't make the adapter a member of any service set. Packet loss and are triggered when the sender's TCP retransmission timeout (RTO) timer expires or a receiver sends Duplicate Acknowledgments to request a missing segment Monitor Mode In order to capture all traffic that the adapter can receive, the adapter must be put into "monitor mode", sometimes called "rfmon mode". TCP Retransmission Timeout Retransmissions are the result of The ARP Proxy is aware of the location of the traffic's destination, and offers its own MAC address as (ostensibly final) destination. IPv4 Data Link Padding Proxy ARP Proxy ARP is a technique by which a device on a given network answers the ARP queries for a network address that is not on that network.
