Remote Monitoring (RMON) is an industry standard feature for traffic
monitoring and collecting network statistics. The Switch software
continually collects statistics about the LAN segments connected to the
Switch. If you have a management workstation with an RMON
management application, the Switch can transfer these statistics to your
workstation on request or when a pre-defined threshold is exceeded.

Broadcast Storm Control is a system that monitors the level of broadcast
traffic on that port.
number of frames per
is blocked until the broadcast
system prevents the overwhelming broadcast traffic that can result from
network equipment which is faulty or configured incorrectly.
A Virtual LAN (VLAN) is a flexible group of devices that can be located
anywhere in a network, but which communicate as if they are on the
same physical segment. With VLANs, you can segment your network
without being restricted by physical connections — a limitation of
traditional network design. As an example, with VLANs you can segment
your network according to:
Departmental groups
■
Hierarchical groups
■
Usage groups
■

LANs".
Your Switch can have its IP information automatically configured using a
DHCP server. Alternatively, you can manually configure the IP
information.
For more information about how the automatic IP configuration feature
works, see Chapter 9 "Using Automatic IP
Statistics".
If the broadcast traffic level rises to a pre-defined
second (threshold), the broadcast traffic on the port
traffic level drops below the threshold.
