Statistics

8.4. Endpoints

Statistics of the endpoints captured.

Tip!

If you are looking for a feature other network tools call a hostlist, here is the right place to look. The list of Ethernet or IP endpoints is usually what you're looking for.

8.4.1. What is an Endpoint?

A network endpoint is the logical endpoint of separate protocol traffic of a specific protocol layer. The endpoint statistics of Ethereal will take the following endpoints into account:

Ethernet an Ethernet endpoint is identical to the Ethernet's MAC address.

Fibre Channel XXX - insert info here.

FDDI a FDDI endpoint is identical to the FDDI MAC address.

IPv4 an IP endpoint is identical to its IP address.

IPX XXX - insert info here.

TCP a TCP endpoint is a combination of the IP address and the TCP port used, so different TCP ports on the same IP address are different TCP endpoints.

Token Ring a Token Ring endpoint is identical to the Token Ring MAC address.

UDP a UDP endpoint is a combination of the IP address and the UDP port used, so different UDP ports on the same IP address are different UDP endpoints.

Broadcast / multicast endpoints

Broadcast / multicast traffic will be shown separately as additional endpoints. Of course, as these endpoints are virtual endpoints, the real traffic will be received by all (multicast: some) of the listed unicast endpoints.
