NOTICE: While you may request any number, the unit is internally limited to a
maximum report size of 20.
As soon as you initiate generation of a report by pressing the “Enter” key or
selecting the “Start” prompt, the Duration value is copied over to the Time
Remaining field. When the specified Duration for the report has elapsed, the
resulting report-specific information will be displayed on the left side of the
screen.
T im e R em a in in g The amount of time (in seconds) for which the Top Talkers report will
capture IP traffic; typically this value is 900 (15 minutes). As soon as you
initiate generation of the report, the Duration value is copied over to the Time
Remaining field.
R ep ort # 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).
S ize Displays the actual number of IP addresses identified as Top Talkers in the
generated report. The maximum report size is 20.
S tart T im e Displays the time at which the Top Talkers report was initiated (based on
System Up Time).
S ystem U p T im e Displays the amount of time that 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 Screen
The IP Gateway is a feature 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
