6.1 Password for SNMP access
6.1.1 Description of password for SNMP access
A network management station communicates with the device via the Simple
Network Management Protocol (SNMP).
Every SNMP packet contains the IP address of the sending computer and the
password with which the sender of the packet wants to access the device
MIB.
The device receives the SNMP packet and compares the IP address of the
sending computer and the password with the entries in the device MIB
(see
on page 196 „Management Information Base (MIB)“) .
If the password has the appropriate access right, and if the IP address of the
sending computer has been entered, then the device will allow access.
In the delivery state, the device is accessible via the password "public" (read
only) and "private" (read and write) to every computer.
To protect your device from unwanted access:
First define a new password with which you can access from your com-
puter with all rights.
Treat this password as confidential. Because everyone who knows the
password can access the device MIB with the IP address of your
computer.
Limit the access rights of the known passwords or delete their entries.
