As soon as the specified Duration for the report has elapsed, the screen will
refresh itself and the resulting report-specific information will be displayed in
the outlined box at the bottom of the screen. This report comprises elements
as defined in the following paragraphs.
Report # This field displays a unique number used to identify the generated report. This
number is generated automatically, is incremented sequentially for each
report, and can be used by management stations for automatic polling (via the
ipadv2.mib).
Size Displays the actual number of IP addresses identified as Top Talkers in the
generated report. The maximum report size is 20.
Start Time Displays the time at which the Top Talkers report was initiated (based on
System Up Time).
System Up Time Displays the amount of time the unit has been operational since it was turned
on or last reset.
The Top Talkers table reports in descending order the IP addresses that have
generated the most traffic during the requested report’s duration. For each IP
address listed, the report displays the number of Rx frames, Rx octets, Tx
frames, and Tx octets that have been passed across it. In addition, the
Timestamp field indicates the time at which a packet was examined for the
specified IP address.
IP Gateway Details Screen
The IP Gateway is a feature of the WANsuite 5165 that allows routing of IP
packets from one network to another using static routes configuration and/or
dynamic routing. The IP Gateway uses Routing Information Protocol (RIP) 1
or RIP 2 or Open Shortest Path First (OSPF) routing.
RIP 1 and RIP 2 are protocols that allow exchange of routing information
between two routers. With that information exchange, a router can build its
own routing tables that later can be used for “routing” IP packets.
OSPF is a shortest path first (SPF) or link-state protocol. OSPF is also an
internal gateway protocol (IGP) that distributes routing information between
routers in a single autonomous system (AS). OSPF chooses the least cost path
as the best path.
While RIP is ideal for small- to medium-sized networks, OSPF is more
suitable for complex networks with a large number of routers. OSPF provides
equal cost multipath routing where packets to a single destination can be sent
via more than one interface simultaneously.
The IP Gateway also supports unnumbered networks. An unnumbered
network is a point-to-point connection without an assigned IP address This
feature reduces the number of IP addresses required.
