Switch Features Explained
17
This system is compatible with the relevant sections of the IEEE
802.1D/D17 standard (incorporating IEEE 802.1p).
For more information about 802.1D and traffic prioritization, see
Chapter
6 “Using Traffic Prioritization”
.
Quality of Service
Traffic prioritization can be taken one step further by using the Quality of
Service (QoS) feature. Quality of Service (QoS) enables you to specify
service levels for different traffic classifications. This enables you to
prioritize particular applications or traffic types.
The Switch uses a policy-based QoS mechanism. By default, all traffic is
assigned the "normal" QoS policy profile. If needed, you can create other
QoS policy profiles and apply them to different traffic types so that they
have different priorities across the network.

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.

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.
