20 CHAPTER 1: SWITCH FEATURES OVERVIEW
RMON 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.
Event Notification
You can configure your Switch to send you notification when certain
events occur. You can receive notification via email, SMS (Short Message
Server), or pager.
For more information about RMON and Event Notification, see Chapter 7
“Status Monitoring and Statistics”.
Broadcast Storm
Control
Broadcast Storm Control is a system that monitors the level of broadcast
traffic on that port.
If the broadcast traffic level rises to a pre-defined
number of frames per
second (threshold), the broadcast traffic on the port
is blocked until the broadcast
traffic level drops below the threshold. This
system prevents the overwhelming broadcast traffic that can result from
network equipment which is faulty or configured incorrectly.
VLANs 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
For more information about VLANs, see Chapter 8
“Setting Up Virtual
LANs”.
Configuration Save
and Restore
Configuration Save and Restore allows the configuration of your Switch
to be saved as a file on a remote server, or to be restored onto the Switch
from a remote file.
