Defining SNMP Settings

Simple Network Management Protocol (SNMP) provides a method for managing network 
devices. Devices supporting SNMP run local software (agent). 

The SNMP agents maintain a list of variables, which are used to manage the device. The 
variables are defined in the Management Information Base (MIB). The MIB presents the 
variables controlled by the agent. The SNMP agent defines the MIB specification format as 
well as the format used to access the information over the network.

Access rights to the SNMP agents are controlled by access strings. To communicate with 
the device, the Embedded Web Server submits a valid community string for 
authentication.

The default community strings for the PowerConnect device are:

•

Public— Allows authorized management stations to retrieve MIB objects.

•

Private—Allows authorized management stations to retrieve and modify MIB objects.

If SNMP is not used:

•

Change the default community strings to prevent unauthorized access to the 
PowerConnect device.

•

Delete both of the default community strings. SNMP management access to the 
PowerConnect device is disabled if no community strings exist. 

To delete the strings:

 NOTE: To use the configure context, users must be assigned a privilege level of 15.
