WEB-BASED BROWSER MANAGEMENT
remotely control and centralized the power management simply by using a Cat5
cable to deliver both power and data.
PoE Conguration
PoE Enabled: When enabled (checked), you can use the port to supply power to
the attached — and thus, powered — device (PD), which in turn allows you to
remotely access that device and monitor its status.
PD Class: This indicates the PD’s classication (Class 0-4).
Delivering Power (W): This is the port’s output power.
Current (mA): This is the port current.
Voltage (V): This is the port voltage.
Power Budget (%): This is the percentage of power usage.
Storm Control
Broadcast storms can occur when a device on your network is malfunctioning or
if application programs are not well designed or properly congured. If there is too
much broadcast trafc on your network, performance can be severely degraded —
even to the point where everything comes to a complete halt. You can protect your
network from broadcast storms by setting a threshold for broadcast trafc for each
port. Any broadcast packets exceeding the specied threshold will then be dropped.
Storm Control Conguration
There are three types of trafc that can be rate limited: Broadcast Rate, Multicast
Rate and Flooded Unicast Rate.
The Rate eld (number of frames per second) is
set by a single drop-down list since the same threshold is applied to every port on
the switch. In other words — regardless of the ow-control settings — when the
threshold is exceeded, packets are dropped.
