Selecting Overview → Analytics → Insight Analytics Packet → TCP displays the TCP dashboard. The TCP tab is highlighted.


Usage Note: Before any analytics can be collected, a valid license must be installed and activated, and a Packet Engine must be configured in Manage Packet Engine. Please refer to this section to configure Packet Engines, third-party tools, upload and manage PCAP files and to manage Packet Engine configurations.


The TCP dashboard section provides valuable information about TCP traffic flowing to and from the switch. Individual widget types provide valuable data and are used for further data drilldown. The upper area of the dashboard displays widgets and tabular data which include:


        • Top Source Host display of top TCP host sources.
        • Top Destination Host – display of top TCP destination hosts.
        • Total TCP Packet Counts – total number of packets collected in the packet capture sample.


Insight Analytics Packet Protocol TCP Upper Dashboard


The middle area of the dashboard displays widgets and tabular data which include:


  • Top Source Domains – display by domain name or address of TCP connection by source.
  • Top Destination Domain – display by domain name or address of TCP connection by destination.
  • Total Bad TCP Counts – total number of bad packets collected in the packet capture sample.
  • TCP Trace – timestamped trace data of TCP packets (average.tcp.seq and average.tcp.ack).
  • TCP Round-trip Delay Time – length of time for packet to be sent, acknowledged and received back.
  • Bad TCP by Time count of bad TCP transmissions by type.
  • TCP Packet Length Distribution – histogram bins showing distribution length of TCP packets.



Insight Analytics Packet Protocol TCP Middle Dashboard


The bottom area of the dashboard displays widgets and tabular data which include:


  • Packet Count By DSCP Distribution – histogram of packet count by Differentiated Services Code Point.
  • Top TCP Source Port – pie chart of TCP source ports by port number.
  • Top TCP Destination Port – pie chart of TCP destination ports by port number.
  • All Packet Length Distribution – histogram bins showing distribution length of all packets.
  • Top TCP Source Mac – pie chart of source MAC addresses.
  • Top TCP Destination Mac – pie chart of top destination MAC addresses.
