• To allow port redundancy that mean if an
operational port fails, then one of the “standby
ports” becomes operational without user
intervention.

116. SNMP SNMP Basic Commands
• Read: It's used by an NMS to monitor managed
devices.
• Write: It's used by an NMS to control managed
devices.
• Trap: It's used by managed devices to
asynchronously report events to the NMS.

• Definition:
A trap manager is a management station that
receives traps, the system alerts generated by
the switch.

129. PoE Product Line Introduction
Managed PoE Switch (PoE Software settings)
 Maximum Power Available: Displays the maximum power supply in watts.
 Actual Power Consumption: This column shows the real-time total power consumption
 System Power Limit: User can modify the value to this column field to limit the total output power for the system
 Main Supply Voltage: This column shows the output voltage of the system for PoE ports
 Firmware Version: This column shows the PoE chip’s firmware version
 Port Knockoff Disabled: Power Management state where one or more PDs have been powered down so that a higher
priority PD may be powered up and yet not exceed the maximum total power available for PDs
 AC Disconnect: Tick this checkbox to monitor the AC impedance on the port terminals and removes power when the
impedance rises above a certain value, for a certain period
 Capacitive Detection: If the port and capacitive detection are enabled, the capacitances state reads in the voltage result
from the constant current. This is then subtracted from the pre-capacitance voltage to get a charge rate. If this charge rate
is within the window of the PD signatures, the device is considered to be discovered.
 Start: Showing with a tick symbol, the system initializes and resets successfully

130. PoE Product Line Introduction
Managed PoE Switch (PoE Software settings)
 Port: The index of PoE ports.
 Enable State: Check it to enable the PoE function to the port.
 Power Limit From Classification : Check it to decide the power limit method; when this check box is ticked, the system will
limit the power supply to the powered device in accordance with the related class
 Legacy: Check it to support the legacy power devices. (PDs may not have IEEE802.3 standard detection signature)
 Priority: Pull down the selection menu item to choose the priority of power supplying.
 Port Limit (<15400) mW: User can key in the power limit value which is under 15.4 Watts.
 Mode: Displays the operating mode of the port.
 Current (mA): Displays the operating current of the port.
 Voltage (V): Displays the operating voltage of the port.
 Power (mW): Displays the power consumption of the port.
 Determined Class: Displays the PD’s class.
