Priority:
Three options are offered for the user to choose, including Normal, Low and High.
Default is Normal. The switch will stop supplying the power to the port based on the
order of the priority LowÆNormalÆHigh in case total power required by all PDs linked to
the switch exceeds the power limit. If the ports have the same priority, the switch will
cease the power supplement from the port with the highest port ID (12Æ1).
Power(W):
The power is consumed by the port.
Current(mA):
The current is supplied to the PD by the port.
Class:
The Class of the PD linked to the port of the switch.
5.10 SNMP Configuration
Any Network Management System (NMS) running the Simple Network Management Protocol
(SNMP) can manage devices equipped with the SNMP agent, provided that the Management
Information Base (MIB) is installed correctly on the managed devices. SNMP is a protocol that is
used to govern the transfer of information between SNMP manager and agent. This protocol
traverses the Object Identity (OID) of the management Information Base (MIB), described in the
form of SMI syntax.
SNMP is passive except for the issuing the trap information. The switch supports a function to
turn on or off the SNMP agent. If you set the field SNMP to Enable, the SNMP agent will be
launched. All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager.
If SNMP is set to Disable, the SNMP agent will not be activated. The related Community Name,
Trap Host IP Address, Trap and all MIB counters will be ignored.
Function name:
SNMP Configuration
Function description:
This function is used to configure SNMP settings, community name, trap host and public traps as
well as the throttle of SNMP. A SNMP manager must pass authentication by identifying both community
names, then it can access the MIB information of the target device. So, both
parties must have the same
community name. Once the setting has been completed, click Apply and the setting will take effect.
Parameters description:
SNMP:
The term SNMP is used for the activation or de-activation of SNMP. Default is Enable.
Get/Set/Trap Community:
Community name is used as the password for authenticating if the requesting network
management unit belongs to the same community group. If they don’t have the same
community name, they don’t belong to the same group. Hence, the requesting network
management unit cannot access a device with a different community name via SNMP protocol;
If they both have the same community name, they can talk each other.
