Source Endpoints – shows the IP addresses and corresponding applications that
were the source of most traffic or packets. The top source endpoints inwards on a
link are the remote services using your bandwidth.
• Destination Endpoints – shows the IP addresses and corresponding applications
that were the destination of most traffic or packets.
• Server-Client Sessions – shows the pairs of connected source endpoints and
destination addresses that exchanged most traffic or packets. A session might
represent, for example, a web browser downloading several web pages with
images from a web server.
• Client-Server Sessions – shows the pairs of connected source addresses and
destination endpoints that exchanged the most traffic or packets. A session could
represent a client’s requests to a web server for several pages and images.
QoS Reports
• Types of Service – shows the ToS levels with most traffic or packets.
• Differentiated Services – shows the DiffServ code points with most traffic or
packets.
Network Reports
• Source ASs – shows the autonomous systems that were the source of most traffic
or packets. Note that a switch does not know anything about ASs.
• Destination ASs – shows the autonomous systems that were the destination of
most traffic or packets.
• AS Pairs – shows the pairs of connected ASs that exchanged most traffic or
packets.
• Bi-directional AS Pairs – adds extra columns showing the traffic and packets sent
from destination to source for each AS pair.
• Source Networks – shows the IP subnets that were the source of most traffic or
packets. Note that a router may not know the subnet of a particular address, and
a switch never knows it.
• Destination Networks – shows the IP subnets that were the destination of most
traffic or packets.
• Network Pairs – shows the pairs of connected IP subnets that exchanged most
traffic or packets.
• Bi-directional Network Pairs – adds extra columns showing the traffic and packets
sent from destination to source for each network pair.
Interface Reports
• In Interfaces – shows the router interfaces or switch ports that were the arrival
point of most traffic or packets. Note that this is only meaningful for the outwards
direction.
• Out Interfaces – shows the router interfaces or switch ports that were the
departure point of most traffic or packets. Note that this is only meaningful for the
inwards direction.
