Snmp > Snmp > Snmp Global Settings - D-Link DGS-1210-10 Manual

4 Web-based Switch Configuration
Note: This switch conforms to IEEE 802.3af and 802.3at standards. The IEEE
PoE standard requires a switch to shut off power to a port if the power draw is
less than 10mA within a 400ms time interval. To support some non-standard
devices that may take longer, you may enable this feature to extend the time
interval to 500ms. If the PD is still not powering on, please contact the vendor
of your device for support.
SNMP > SNMP > SNMP Global Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed
specifically for managing and monitoring network devices. SNMP enables network management stations to
read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to
configure system features for proper operation, monitor performance and detect potential problems in the
Switch or LAN.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the
device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage
the device. These objects are defined in a Management Information Base (MIB), which provides a standard
presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the
MIB specifications and the protocol used to access this information over the network.
The default SNMP global state is disabled. Select Enable and click Apply to enable the SNMP function.
Trap Settings: Specifies whether the device can send SNMP notifications.
SNMP Authentication Traps: Specifies the device to send authentication failure notifications.
Device Bootup: System boot-up information.
Illegal Login: Events of incorrect password logins, recording the IP of the originating PC.
Port Link Up / Link Down: Copper port connection information.
RSTP Port State Change: Events of a RSTP port state changes.
Firmware Upgrade State: Information of firmware upgrade - success or failure.
PoE power On / Off: Status of power per port.
PoE Power Error: The four trap events are: power over loading, short circuit, thermal shutdown and
power deny.
PoE over max power budget: When the system supplies power to PDs and hits the max PoE power
budget, the system will send out this trap message.
Loopback Detection occurring / recovery: Specifies the device to send SNMP Trap when
Loopback Detection occurring and recovery.
Note: For the PoE Port Settings table, if the
classification was shown as "Legacy PD", it will be
classified to non-AF PD or Legacy PD.
